Inferential Statistics to Evaluate Sample Data Inferential

inferential statistics to evaluate sample data.

Inferential tatistics are used to determine whether one can make statements where the results reflect that would happen if we were to conduct the experiment again with multiple samples. With inferential statistics, you are trying to reach conclusions that extend beyond the immediate data alone via inference. For instance, inferential statistics infer from the sample data what the population might think. Another example, inferential statistics can be used to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in this study. Thus, inferential statistics make inferences from data to more general conditions; whereas descriptive statistics simply describe what's in the data.

When conducting research, inferential statistics that are useful in experimental research design or in program outcome evaluation. The simplest inferential test is used when comparing the average performance of…… [Read More]

Inferential Statistics What Are the

In this way, true experimental research attempts to control for all confounding variables, or at least consider their impact, while attempting to determine if the treatment is what truly caused the change. Note that individual background variables such as sex and ethnicity do not satisfy the requirements of true experimental design since they cannot be purposively manipulated in this way (Practical assessment research and evaluation).

True experiments are different from experimental design in that they are the only experiments that allow researchers to make causal conclusions based on study results and, therefore, provide greater internal validity (True experiments). It is only through random assignment that researchers can be assured that groups are truly comparable and that observed differences in outcomes are not the result of extraneous factors or pre-existing differences (Practical assessment research and evaluation). This means that the researcher needs so have control of the situation to have a…… [Read More]

Analysis of Inferential Statistics and Discontents

Inferential Statistics and Their Discontents

The notion of conducting statistical testing is increasingly important because of the significance testing is the basis of statistics. Inferential statistics is an important part of this process despite the necessity of descriptive statistics, which help in data exploration and interpretation. Actually, one of the most important aspects of inferential statistics is significance testing largely because this is what statistics are centered on. Generally, inferential statistics mainly focus on statistical concepts and thinking. There are several components to consider when examining inferential statistics including degrees of freedom, what to infer, General Linear Model, parametric and non-parametric statistics, and assumptions of the statistical test.

Degrees of Freedom and How they are Calculated

Degree of freedom is a term that is commonly used to refer to mathematical equation utilized in statistics as well as other fields like chemistry, physics, and mechanics. However, many researchers seemingly struggle to…… [Read More]

Decision Modeling Inferential Statistics

Inferential Statistics: Decision Modeling

Decision Modeling: Inferential Statistics

Decision models are important components of inferential statistics. They are crucial in helping researchers choose the most appropriate statistical test to use for their study. This text presents the various steps involved in decision modeling, and uses two studies to demonstrate how such models can be used to guide the decision on what test to use.

Decision Models in Inferential Statistics

Decision models play a crucial role in inferential statistics; particularly in assisting researchers identify the most appropriate statistical test to use for their study. The decision about what statistical test to use for a study is made in a series of steps laid out in the decision tree or decision model. Each stage requires the researcher to answer a simple question about the investigation. This text summarizes the basic steps of a decision model, and provides a demonstration of how such…… [Read More]

Descriptive and Inferential Statistics

Descriptive statistics is an style of analysis that is used when wanting to describe the entire population under study. But the population studied must be small enough to include every case, or each subject. ("Definition") On the other hand, inferential statistics also studies a population, but the purpose is to expand the results to include a much larger population in general. (Healey) In descriptive statistics, the results can be used to make conclusions about the population studied, and only that particular population. While inferential statistics allows a researcher to make conclusions about larger groups based on the results of the study of one particular group.

Descriptive statistics can be used when studying a population, such as one particular class in a school, or one group of workers, and the results are to be used to draw conclusions from only that group. For example, the…… [Read More]

Inferential Statistic Tests Used in Study What

inferential statistic tests used in study. What were these tests typically used for? Why were they chosen here?

The objective of the study was to analyze the true costs of hypertensions. The researchers did this by analyzing the data of four patient groups using propensity score matching to control for possible bias in cost estimates. The regression model that followed estimated for costs of hypertension by controlling for sex, length of hospital stay, Charlson comorbidity index, region of residence, and urbanization of residence.

Researchers used the 2005 MarketScan CCAE database, that contained information about hospitalized patients who belong to more than 100 health insurance plans offered by about 40 employers, in order to estimate hypertension associated hospitalization costs for patients with hypertension as a secondary diagnosis.

The problem was that since more than 95% of the hypertensive patients in the CCAE study had hypertension as secondary rather than primary diagnosis,…… [Read More]

Statistics the Intent of This

There are also ethical issues pertaining to the observational method that will be discussed later in this paper.

Experience surveys are widely used throughout qualitative research studies, due to their focus on bringing greater insights into the study through the interviewing of experts in chosen fields. There is also a strong focus on how to gain insights of experts in the future definition of the methodology being created, and how the research objectives can be more effectively accomplished as well. Experience surveys also are often used in the first stages of a research project. Another qualitative research technique, the case study, takes the concept of gaining insight and applies it to an organization and its dynamics. A case study seeks to define and complete a thorough analysis of one or more specific circumstances within institution of interest. The goal of case studies is to measure the relationships, inter-dependencies and cause-and-effect…… [Read More]

Statistics in the Hospital Setting

During the course of performing my professional duties at College Hospital, which is a psychiatric facility located in Cerritos, California, I encounter patients who are struggling to maintain some semblance of a normal life despite struggling with one or more mental illnesses or psychological impairments. College Hospital is a 187-bed, free-standing psychiatric care unit which is accredited by The Joint Commission and licensed by the California Department of Health Services, and part of my job is assist in providing a wide range of psychiatric services for a wide range of patient demographics. As the leader in Partial Hospitalization Programs throughout the greater Los Angeles and Orange County metropolitan areas, College Hospital relies on the accurate and efficient use of statistics to ensure positive patient outcomes.

Healing With Statistics There Are Numerous Ways

Healing with Statistics

There are numerous ways in which statistics are used in a standard healthcare organization. Statistical measurements and analyses are used to track patient costs and hospital/healthcare organization expenses, to determine appropriate medication levels, to assign work staff and maintain proper human resource levels, and for a wide variety of other applications and areas of concern. In many ways, the quality and the cost-effectiveness of care provided by a typical healthcare organization is directly related to the quality of the statistical data the organization collects and assesses. Without such statistical analysis and manipulation, direct healthcare providers as well as administrators within the healthcare organizations would be left with little more than anecdotal evidence and subjective perceptions and judgments when it came to making decisions for patient health and/or organizational fitness, thus the importance of statistics in such organizations is difficult to overstate.

The most basic level of analysis…… [Read More]

Hear the Word Statistics the

Being able to express statistical results in ways non-statisticians can understand, and explaining those results correctly in language that does not mislead or confuse is becoming a lost art, if the popular media are any indication. Entrepreneurs will use these visual display techniques to increase productivity, notice patterns that may go unrecognized in tabular or numerical reporting, and communicate results quickly without requiring extensive and subjective verbal explanation.

Inferential statistics will become increasingly useful even before graduating college, if peer-reviewed studies in consumer psychology, economics and marketing become more rather than less proportional in coursework on the way through graduate school. Some of the coursework I read for other classes contains statistical procedures I am unfamiliar with even after this course, and thus learning more statistics should explain a significant improvement in grades in my other classes, hopefully with a strong (? = .001) effect size! Knowing how likely flaws…… [Read More]

Role of Research and Statistics

Assessing descriptive statistics in the form of raw data is often a critical component of primary research when constructing an experiment, where the experimenter then can have control over the various variables affecting the specific phenomena that is being studied. the, in the actual experiment, the tendency of other information to influence statistical results can be restricted or taken into consideration, and a control, or unaffected group can be included to see what the population resembles without the experimental variable. Descriptive statistics, in short, can be useful, but many variables can affect their results, so they cannot always be relied upon.

In contrast, "inferential statistics are used to help psychologists draw inferences, or conclusions, from the data obtained from their research" ("Statistics in psychology," 2008, Encyclopedia of Psychology). For example, inferential statistics are collected when researchers test if watching a particularly violent film makes a group of subjects more apt…… [Read More]

Business Statistics Is the Study

Therefore to form a basis of good decision making business people should be able to understand how statistics can be applied in the description of markets, advertising development, price setting and how they can best respond to the consumer demands that are often changing (Petryni, 2010).

Statistics can be used in various situations within a business for instances; incase a business wants to venture into new markets statistics can be used to inform the business decisions in the definition of target consumers. The statistical analysis of the trends of consumers, purchasing powers and preferences can be useful in making decisions before venturing into a particular business.

Another situation can be where decisions on the branding and advertising products or services the statistical analysis may aid in the definition of the consumers who are targeted, provide information about the industry one wants to venture in and description of the buying trends.…… [Read More]

Online Statistics and Probability Theory

Online Statistics
Part 1
Probability theory is an aspect that is applicable on an everyday basis. A particular situation in which I may use probability theory to reach a decision in public management is to investigate equal employment prospects within the organization. For instance, there is a need to assess whether the organization hires women in the same manner as men, especially in positions that do not necessitate certain gender traits. Therefore, in this case, probability theory can be beneficial in probability theory, specifically Bernoulli process. That is, a process can either generate two possible outcomes, which are male or female. Probability plays a pivotal part in this regard because the probability of a certain results is the proportion of times that outcome would take place in a long and extensive run of repeated observations. In this instance if men and women are equally represented in the labor force, then…… [Read More]

Organization Dynamics Basic Statistics

Organizational Dynamics

L. Jones

In my job as a Health Readiness Coordinator, I am required to exercise a high level of skill in communication, leadership, organization, as well as basic statistical analysis. In specific, I have found the following principles of group and organizational dynamics, leadership styles, and basic statistics to be invaluable.

One of the first ways in which a Health Readiness Coordinator begins his or her relationship with a client is by helping them to make relevant decisions. Of course, the best way to begin this process is by utilizing a "break down" method that separates the decision into defined components. Specifically, these include defining the problem, collecting the relevant data on all possible choices, evaluating present alternatives, and finally, making an informed decision (Amos, 2004). Additionally, I have also found it useful to add a final reflection step in which I evaluate the success of the decision,…… [Read More]

Science if Conducting an Experiment

It is often easier to impose this sort of control in a laboratory setting. Thus, true experiments have often been erroneously identified as laboratory studies" (Woolf, 2012). True experiments rigidly control for validity by attempting to isolate variables so that only a single independent variable is studies. The independent variable "is the variable that the experimenter manipulates in a study. It can be any aspect of the environment that is empirically investigated for the purpose of examining its influence on the dependent variable" (Woolf, 2012). Furthermore in true experiments, the subjects are randomly assigned to the experimental and control groups. Finally, true experiments are double blind, which means that neither the experimenter nor the subjects know whether the subjects are in the experimental or control groups (Woolf, 2012).

True experiments differ from experimental designs in the level of control that exists in each different type of research. An experimental design,…… [Read More]

Psychological Research It Is Difficult

We have also talked about the "blue print" of a study, or the logical model of proof which guides the researcher throughout the entire study -- i.e. The research design. It is by which the investigator determines the relationships between variables being tested. We have discussed true experiments, its nature and validity issues as well as quasi-experimental designs. We also provided a discussion of the difference between these two designs.

What is worth nothing, I believe, is the importance of a good research design. A good research design theoretically leads to good data. Hence, during the conceptualization of research design, careful thought needs to be employed.

Lastly, our research considerations, on which kind of statistical tool to use, whether to use sample or population, and/or which research design to employ, should always be anchored in our research objectives, on the things that we aim to know through the study.

Figure 1 shows that the majority of readings surrounded this mean and median cluster on both sides to symmetrical degree, as opposed to appearing grouped highly above or below. The result of this all is a relatively high value for the first standard deviation, which corresponds to meaningful Kurtosis but very little skew -- Table 1 reveals less than .01 skewness, which means the results are highly symmetric (Brown, 2008-2012, n.p.). Negative Kurtosis reflects the concentration of data in these shoulders (DeCarlo, 1997, p. 294), which is supported by two modes one either side of the mean-median (Figure 2, Appendix IV shows this bimodality, not revealed in Figure 1). While this indicates less than normality and warns that parametric inferential statistics should be scrutinized carefully and non-parametrics (CHI-Squared; rank-sum; Wilcoxon's, etc.) run for corroboration in case the 100 value turns out to be an outlier, these results show more symmetry…… [Read More]

Larger Population of Cases Term

Part 2

One of the important issues that this type of statistical sampling conducted by the substitute teacher was her choice of students to inquire about their test results. In a class size of 30, 5 students hardly represent the whole class; in fact, in order to accurately determine the performance of the class as a whole, it is recommended that all students be asked of their test results. The sub-teacher can also generate a sample, group of students who will represent the total population, which is the whole class. The sample should be objectively chosen, and since the method of choosing the students to report on their exam performance was based only on the fact that they all belonged to the front row of the class, then the sample generated by the teacher is biased. An alternative to this problematic method of sampling would be to choose one student…… [Read More]

Statistical Analysis of Restaurant Patrons

Many patrons tip based on how quickly their food is delivered, and if it is hot or not, how it tastes, did it meet the patrons' expectations or not for this specific type of food, what is the frequency of the patrons' dining on this specific type of food.

There are also an entire series of attitudinal questions regarding why this specific restaurant was chosen, and these could range from convenience for a family meal together, or for a special occasion. Clearly expectations are significantly higher for those respondents going out to dinner for an anniversary, birthday, or significant family event - all instances were respondents would be going to more upscale restaurants.

Conselling Master Questionnaire

Describe the Boolean Approach (Hauser, 2009 p. 18)

In order to use counseling databases to search for information, it is important to develop appropriate search practices. The terms one types when searching will most likely provide the results owing to their meaning. Therefore, it is up to an individual to come up with a search strategy and learn the tips of using counseling databases. The tips will assist an individual in acquiring high quality information in the required amount. Additionally, an individual is likely to add intelligence to their search strategies, the more one knows the tips of searching, and they are likely to obtain better results.

The Boolean approach is among the techniques that will generate useful results when using counseling databases, and it aims at supporting scholarly research. On the other hand, Boolean operators are words, which have unique meanings that instruct the database to…… [Read More]

Healthcare Environment Palese Et Al 2011 Argue

healthcare environment, Palese et al. (2011) argue there is no effective data to support that patients' satisfaction is correlated with a nursing care. Moreover, there is evidence revealing uncertainty in the nursing care environment since there is lack of identification of caring consequences. While the patient's satisfaction has been linked with nurses' caring behaviors, however, there is no empirical evidence to support "the effect of caring on patient's satisfaction." (Palese, Tomietto, Suhonen et al. 2011 p 342). Moreover, there is ongoing scientific debate to ascertain the meaning of caring with reference to a caring context, and working environment to support nurse is caring. Palese et al. (2011) also reveal that there is scanty of studies that focus on the "international cross-cultural nursing studies" (p 342) despite that the European Union has opened its border for free movement of nursing professional to enhance common base and safeguard equal opportunity that will…… [Read More]

Caring Nurses

Palese et al. (2011). According to Wood & Haber (2014) " the critique is process of critical appraisal that objectively and critically evaluates a research report's content for scientific merit and application to practice." Using the text's understanding of this examination this essay will explore the article and examine it for practical use and valid argument.

The problem that this research is premised upon is the idea that nurse's caring has gone mostly under examined in relation to patient's view of quality of care. The role of caring within the nursing profession is described as the factor which inspired this research. The variables within this examination are the patients' satisfaction measured against the practice of caring executed by nurses in their professional duties.

This problem is clearly identified and can be empirically tested as the article revealed in its conclusions. To help lessen the distortion of the ideas and values…… [Read More]

Epidemiological Data and Then Exploring Possibility of

epidemiological data, and then exploring possibility of a causal connection between lack of government funding for community-based treatments and increase in HIV incidence in queer male communities.

Both statistical descriptive and inferential tests will be employed.

The descriptive tests summarize and describe the data. These would include frequency analysis e.g. Of the amount of men diagnosed as queer, and frequency that the participants experienced homophobia. Univariate analysis would focus on one variable, e.g. frequency of homophobia, by analyzing the mean, the distribution, the central tendency, and the dispersion of the occurrence.

The distribution would provide some assumption of the pattern of the range: whether normal or skewed.

The central tendency would, in this case, measure the mean of the data, i.e. average number of males that experienced discriminatory treatment. Dispersion would be another descriptive tool that measures the spread of values around the central tendency, i.e. range and standard deviation.…… [Read More]

Females in Military

Should females in military be allowed to lead combat units?

Gender discrimination is a wide exercised practice that is witnessed in the military organization as well. Women in the current times are equally challenging and capable of being a significant part of combat units. However, this subject matter has come under numerous arguments and disagreements with controversial results. In this regard, this study aims and intends to carry out a profound study that can determine whether females in military should be allowed to lead in combat unit or not. The study is a synthesis of both primary and secondary research that can aid the researcher to conclude with meaningful information.

Neuman 2003 Researchers Frequently Need

The median is the middle point in a series and represents the 50th percentile, meaning about half the cases are above it and half below it. The easiest application of this technique is to organize the scores from highest to lowest, and then count to the middle. Therefore, in those cases where there is an odd number of scores, the calculation is straightforward; even numbers require some extra analysis to identify the median (Neuman, 2003).

This measures if the easiest to use (Lomax, 2001) and can be used with nominal, ordinal, interval or ratio data (Neuman, 2003). The mode is simply the most common or frequently occurring number in such a series, but a distribution can have more than one mode (Neuman, 2003).

Sources: As indicated.

Conclusion

The research showed that the three common measures of central tendency are mean, median and mode, although other indexes also exist. The research…… [Read More]

Conducting Analysis in Research Studies

statistics statistics and inferential statistics.

Descriptive statistics and inferential statistics are used for different types of designs. For example, correlational studies will utilize descriptive statistics to measure a set of data's central tendency along with the way variables vary and relate to one another. A Pearson r would be a type of descriptive statistics test conducted to evaluate the strength of the relationship or if there relation goes in any one direction but descriptive statistics can also be used in causal-comparative design studies to measure data variability (Statistics for the non-statistician, n.d., p. 70). Inferential statistics on the other hand are used to compare means (typically a t-test is conducted) and statistical significance is determined by whether the p value is > or < than alpha (commonly .05) (Statistics for the non-statistician, n.d., p. 61).

Another way to think of descriptive statistics is that they are "used to synthesize and…… [Read More]

Criminal Justice and Criminology Interpreting

This result is somewhat different from that of a colleague which found that teenagers who are more likely to be at the high school level of education responded in higher numbers. This difference can be attributed to the differences existing in the posts. The other post was on the use of the GPS feature on smart phones. Teenagers are more likely to engage in tech talk compared to other age groups.

Conclusion that can be drawn about interpreting data

ata interpretation is an important exercise that comes after the data is analyzed. It helps to draw conclusions from the data itself. In the data interpretation process, it is possible to tell whether the hypothesis has been accepted or not. It is also possible to know how the sampling or data collection methods affected the results that have been collected. ata interpretation also helps to provide the answer to the research…… [Read More]

During the research, there was data that was collected and having been plotted on the histogram and the appropriate scatter plots, the obtained results gave a descriptive portrayal of the finding from the variables. The histogram and the scatter plot gave the pictorial correlation between the time spent and the frequency of the attendance of the gym session with the audio and visual aids and on the other hand without the aids. The descriptive approach enabled the clear display of the findings such that the correlations were seen clearly hence giving a descriptive statistics at the end of the collection of the data. This descriptive data hence has the potential of giving the researcher easy time in explaining the correlation between the variables involved. The descriptive data also gives the researcher the basic information about the variables that are in a dataset for…… [Read More]

Bmx Racers Research Whether it Is Qualitative

BMX Racers

Research, whether it is qualitative or quantitative in design, must be succinct, thorough, and best fit in order to achieve the intended results. Without proper controls, definition, and well-defined objectives the research endeavor is simply an ad hoc attempt to gather data and explain a particular phenomenon. Research must also command interest, enthusiasm, and passionate commitment to that which is being investigated. The purpose of the proposed research is to determine the differences that possibly exist in and amongst BMX (Bicycle Motocross Racing) racers with respect to the effect this extreme sport has on those who participate.

In order to accomplish the goals of the intended research project data will be collected by way of a short survey questionnaire wherein participants will be asked four (4) questions relative to the following:

The number of body scars received while participating in the sport.

This project is a quantitative study involving descriptive statistics. Descriptive statistics allow for summations about objects (FAQs-Descriptive & Inferential Statistics), in this case m&ms. With the exception of measurement error, descriptive statistics can clarify large volumes of data with no uncertainties about the values. Each descriptive statistic reduces lots of data into a simpler summary (Trachim, 2006). The sample was collected by purchasing 1.67 oz. bags from different retailers from around the U.S. The colors were individually counted with the total number of candies per bag. Statistical analyses were conducted to determine whether the distributions were as the targets required, including the mean, standard deviation, and 95% confidence intervals. Half of the colors of the m&ms were off target, which indicates problems in the manufacturing and packaging processes. The blue, yellow, and brown did not show sufficient evidence, meaning they were off target for the target distributions.…… [Read More]

Normal Distribution

Probability and Normal Distribution

In the study of statistics, probability is a key concept that illustrates and describes the randomness and likelihood of an event from happening given the number of ways it can happen and the number of outcomes that this event could probably happen. That is, probability in statistics helps determine how likely an event is going to happen, as the certainty of the event happening cannot be determined specifically and how many times, but the likelihood of it happening can be determined. Using probability for the researcher, statistician or business decision-maker would mean going through all possible outcomes for an event or outcome to happen. andomness and probability makes it possible for an event to not happen at all; or there is an even chance that the event may or may not happen; but there is also a likelihood that the event could happen after all. These…… [Read More]

Coleman et. al., (2009) Patient Perceptions of Obstetrician-gynecologists' Practices elated to HIV Testing. Maternal Child Health Journal 13: 355-363.

What were the objectives and hypothesis of the study?

The Coleman and colleagues (2009) study had four main objectives. The researchers sought to determine (1) the number of patients who were tested for HIV by their obstetrician-gynecologist (OBGYN); (2) investigate the attitudes of knowledge of patients concerning HIV testing and their personal risk status; (3) elucidate the key reasons that lead to declining an HIV test; and (4) examine how patients recall their OBGYN's approach to HIV testing.

The researchers hypothesized that women in their sample who were pregnant, seeking preconception care or who were women with risk factors for HIV infection would demonstrate recall for their OBGYN recommending an HIV test.

What was the overall goal/recommendation of the study?

The studying was predominantly seeking to determine whether or not female…… [Read More]

Americans and Canadians Differ in Their Online

Americans and Canadians Differ in their Online Spending Habits?

It is no secret that the economies of most industrialized nations have been sluggish over the first part of the 21st century. However, consumer confidence in North America may be on the rise. For instance, according to a March 2012 euter report consumer confidence for Americans and Canadians remained stable as 26% of Americans (the highest level in over a year) and 28% of Canadians believed that their economies would improve over the next year. These figures are taken from the BC U.S. Consumer Outlook Index and the BC Canadian Consumer Outlook (BC COI and BC CCO respectively; euter, 2012). Of course this is really not as optimistic as the researchers depict it, because 26 or 28% does not represent a majority. Therefore, the real news is that the majority of citizens in these countries DO NOT believe there economy will…… [Read More]

structure the research, to show how all of the major parts of the research project -- the samples or groups, measures, treatments or programs, and methods of assignment -- work together to try to address the central research. Creating an effective research design is likely to be one of the most difficult and eminently useful tasks in drafting a proposal. An effective research design links abstract and stylized concepts and questions with the empirical world's complexities and challenges.

A research design must at once be specific and highly flexible. It must be expansive enough to adapt these very complexities while still pointing you towards relevant data. The methods you use should be extensions of your substantive question and epistemological orientation. Contrary to some disciplinarians' claims, there is no single research model that one can or should follow. Numerous alternatives must always be considered and choices made.

By the time you…… [Read More]

chronic pain

diagnoses, pain is a common complaint among inpatients. In the U.S. alone, approximately 100 million patients experience chronic pain (Alaloul et al., 2015). Pain negatively affects numerous aspects of an individual's life, such as sleep, quality of life, and physical functioning. Pain is also associated with negative psychological outcomes like depression, extended hospitalization, and a huge economic burden. In the U.S., for instance, pain imposes an estimated cost of $635 billion on patients and the healthcare system as a whole (Alaloul et al., 2015). Ineffective management of pain can have a negative impact on patient satisfaction, underscoring the need for more effective interventions.

Effective pain management is particularly important in postpartum care, where the experience of pain is common (Eshkevari, Trout & Damore, 2013). However, the management of pain in postpartum care remains quite ineffective, with up to 20% of postpartum patients reporting dissatisfaction with pain management (Niemi-Murola et al.,…… [Read More]

Technology on Personal Relationships the

In many ways, students live both in the land-based or physical world as well as in the virtual world; leading what some considers parallel lives.

Helliwell & Putman (2004) posit that social networking sites may offer an avenue for the development of greater social capital which may serve to further reinforce students' likelihood of integrating Facebook and other social media sites into their regular routines. A suggestion made as to the possible reason for the purported decline in mature interpersonal relationships is social media and advances in technology Helliwell & Putnam, 2004.

The following study will build a base of knowledge regarding several popular social media sites including Facebook, and examine the role social media plays in a college students' development and interpersonal relationships.

Technology has revolutionized and transformed the way in which people relate in one another and in this way it has greatly impacted the communication between people.…… [Read More]

Workers With in Small Firms Chapter I

Workers With in Small Firms

Chapter I outlines the problems this research aims to address, namely an information gap that may, if filled, enhance employment for potential and existing workers with disabilities. This chapter defines the problem background, purpose of research, theoretical framework through which conclusions will be drawn from survey data gathered in the field, the research questions the survey instrument seeks to answer, the definition of terms those questions employ and limits and delimitations of the intended research. Once those parameters are outlined, the claim this argument attempts to support, that closing a gap in information describing satisfaction and productivity for workers with disability in small firms below conventional definitions of 500 workers or less may improve employment for a historically marginalized population, leads to conclusions that thus inform the subsequent methodological and analytical chapters.

The problem with using this approach is that anomalies could occur, which will make the figures incorrect. To avoid these kinds of oversights, descriptive statistics is looking at a wide variety of numbers. This allows researchers to corroborate the underlying trends with one another. (Descriptive Statistics 2006)

Inferential data is when you are trying to determine what the respondents of the sample are thinking by looking beyond the data. This is accomplished by using probability to make judgments about what the data means by: looking at the differences between the control group and the independent variable. Two types of tests that are appropriate include: the t test and analysis of variance. (Inferential Statistics 2006)

Effective Nursing Handoffs in Nursing Practice

Nursing Handoff Communication esearch

Nursing handoffs are important components in the modern health care setting given their role in transfer of the responsibility and authority of care from one practitioner to another during shifts. Generally, nurses work in different shifts when providing patient care in order to reduce their work burdens and potential stressful moments. Therefore, nursing handoffs help ensure continuity of care during a patient's stay in the health care facility. Despite the significance of nursing handoff in continuity of care, this process has been characterized by numerous communication problems. In most cases, nursing handoffs are substandard and contribute to several challenges in enhancing patient outcomes and satisfaction. This study seeks to examine communication problems in nursing handoffs with a view of identifying effective strategies towards enhancing this process. This issue is important in current nursing practice with regards to enhancing patient outcomes and satisfaction. Effective nursing handoffs are…… [Read More]

Richmond VA Been Impacted by

Dropping the interest rates and doing other things to make consumers breathe a little easier when they make a purchase shows that the country is pulling together, which is something that the recession is teaching almost everyone in America - that people are all alike in many ways, and they need to help each other out as much as possible.

Is the fiscal policy maneuvering a good idea? Many people think that using fiscal policy is not a good idea to try to stimulate the economy. The reason for this is that fiscal policy has a built-in system of checks and balances. For example, when the unemployment rate rises, the amount paid out in unemployment benefits also rises. It is just the way the system works. Many think that people mess with that system at their own peril. The concern is that the whole thing will get out of balance…… [Read More]

Military Retirees Are Entitled to

First of all only a scant few of these Veterans groups will acknowledge the "promise" of free health care; for the most part these groups will tout the benefits already promised by the Veterans Administration and assert that cuts in these benefits are the same a broken promise-or contractual breach in legal terms. The idea of the United States military making a "promise" or forging a legally binding agreement between individual veterans or groups of veterans is barred by the United States Constitution. As will be demonstrated in the Literature eview, specific Constitutional language from Article I give Congress and only Congress the express authority to make laws and regulations pertaining to the armed forces. Therefore, the idea the military breached a contract with service members is, ultimately, inherently inaccurate. Combining the lack of specific language within the materials provided by any governmental agency with the clear language of the…… [Read More]

Analysis of Null Hypothesis Significance Testing

Nhst

Compare and Contrast Null Hypothesis Significance Testing (NHST)

The most commonly used statistical technique for testing the impact of the factor being discussed on observations is Null Hypothesis Significance Testing (NHST). Consequently, NHST is the famous approach to inferential statistics, especially when conducting quantitative research. Despite being the dominant approach, NHST has also become increasingly controversial given the belief by a considerable number of people that it is a flawed statistical method. The controversy and consideration of Null Hypothesis Significance Testing as a flawed statistical approach has contributed to the development of alternatives whose proponents consider more beneficial or advantageous unlike NHST. However, an understanding of Null Hypothesis Significance Testing requires correct interpretation of p values.

Meaning of p = .05

P value is commonly used across statistical approaches including regression analysis and t-tests because it determines the statistical importance or significance in testing a hypothesis. According to Frost…… [Read More]

Multivariable Statistical Control Charts

Hoteling T^2 Control Charts

Multivariable statistics is an aspect of statistics that involves analysis of more than one variables. In other words, the multivariable analysis is concerned with the statistical analysis of more than one variables how they are related to one another. Some problems involve using the multivariable data using multiple regression or linear regression, and one of the aspects of the multivariable analysis is an area that involves analysis of quality control using the linear regression. Contrary to the univariable analysis that uses two variables, the multivariable analysis uses two or more independent variables or dependent variables. The concept independent variables are the variables manipulated by the researcher to carry out the analysis. With this control, the researcher will be able to correlate the dependent and independent variables. However, the manufacturing companies are increasingly using the multivariable statistics to enhance product quality. In the contemporary manufacturing environment, increasing…… [Read More]

Compliance of the Sarbanes-Oxley Act

Pattern of inductive reasoning is as follows: Theory ?Tentative Hypothesis ?Pattern ?Observation. While inductive approach is concerned with the open-ended explanatory, deductive reasoning chooses a narrow perspective by testing or confirming the hypothesis. (Trochim, & Donnelly 2007). Typically, inductive reasoning chooses qualitative approach to test the hypothesis. However, the deductive approach employs quantitative method to test hypothesis before arriving at confirmation. In qualitative research, it is not necessary to generate hypothesis to begin research, however quantitative studies make use of hypothesis to begin research. One of the advantages of deductive approach is that the researcher is able to test the hypothesis by using data. The limitation of quantitative approach is that the hypothesis could only be tested when there is enough data. (Ali, & Birley, 1998).

In accounting research, testing the hypothesis with the use of the statistical analysis is the common method to arrive at confirmation. The validity of…… [Read More]

Nurses Preparedness to Care for Women Exposed to IPV

Sundborg et al. (2012) conducted a quantitative study, which examined the preparedness of nurses to provide care for women who are exposed to intimate partner violence (p.1). The study was carried out on the premise that intimate partner violence (IPV) has significant effect on women's health. Therefore, nurses need adequate preparations to identify such victims and provide suitable interventions. While the study provides significant insights relating to nurses' preparedness in handling such patients, there are some drawbacks associated with it as demonstrated in this critique.

The sample for this study was randomly selected from the 174 primary health care centers that employ approximately 1,200 active nurses in Stockholm County (Sundborg et al., 2012, p.3). Since the sample was selected randomly, a probability sampling method was utilized by the researchers. Every individual in the sampling population had equal chance of being included in the study. The results from this sampling method…… [Read More]

Discussion Board Questions

size is an important step in the sample selection process. In Negarandeh, Bahabadi & Mamaghani's (2014) study, the procedure used to determine the sample size is clearly described. Following a pilot study, using the sample size formula, and based on the population of the hospital in which the trial was carried out, the authors estimated the sample size at 100 participants (50 participants in each group). evealing how the sample size was determined enables readers to ascertain the extent to which the sample selected is representative of the larger population (Thomas, 2009). In quantitative research, a representative sample is important for improving the generalizability of findings (Bryman, 2008). In this case, the sample was quite representative of the study population. The study setting was a 530-bed hospital. The trial was specifically conducted in the medical surgical ward, which had 40 active beds, meaning the findings can readily be generalized to…… [Read More]

Why is it important to acquire necessary skills in research for a counselor?

Clinical counselors are doctoral-level providers of health services skilled in counseling clients while evaluating and treating emotional and mental disorders utilizing scientific theories and methods. Adequate interpersonal correspondence skills are imperative. A clinical counselor must have the ability to listen eagerly and understand what customers communicate with them, and have the capacity to talk clearly with customers about sensitive issues. This occupation also requires basic thinking skills, as clinical therapists must have the capacity to utilize logic and reason to solve and interpret complex issues. Houser writes: "… but I believe acquiring the skill to evaluate how knowledge was generated is a key skill in functioning as a professional and dissociates those with advanced graduate degrees…… [Read More]

Effects of Video Games on Short Term Memory

video games have on short-term memory. esearchers normally study action games, but quest/puzzle games were also included in this study, to allow for direct comparison of different game types along with a control group. In this research, we looked at three different types of short-term memory, the visual-spatial dimension, verbal and numerical. We examined some correlations between improved memory and video game usage. However, not all of the null hypotheses were confirmed in this study, meaning that there is room for future study. In particular, it has been established that quest/puzzle games are correlated with higher visual-spatial and verbal short-term memory, but it has not been determined if differences between baseline abilities amount the study participants might have influenced this result. This, therefore, would be one avenue for future study that has been opened up. This study contributes to the growing body of knowledge with respect to the influence that…… [Read More]

One of the questions may, for instance, be "ow secure do you think your company's computer…… [Read More]

Statistical Information the Role of

Another statistical measure that should be implemented is the use of statistical techniques to measure the side effects of certain drugs and medications given to patients.

Possibly one of the most important statistical aspects that should be applied to modern nursing is the creation of clinical pathways in hospitals. The development of clinical pathways are related to "…attempts to reduce hospital utilization" and "cost-containment initiatives" ( Lagoe, 1998) There are many variables that have to be statistically considered in this regard and statistical analysis of data provides insight into the clinical pathway; for example, an analysis of the variables relating to the hospital population.

While data and information collection processes are important, they are dependent on accurate and dependable analysis techniques to be effective and of use in nursing. While nursing is known as a profession that stresses qualitative aspects, there is an increasing emphasis on the accurate quantitative side…… [Read More]
