SPSS Data Analysis
Does the number of average study hours per week during the semester accurately predict final exam grades?
Independent variable: average number of study hours per week.
Hours is continuous data because it can take on any value below 168 hours, which is the number of hours in a week. Even though the data is reported in integer form the 'hours' data is continuous.
Hours data is quantitative, since it can be summed, divided, and multiplied.
Hours data is ratio data because it has a natural zero point. For example, the range of hours that a student can theoretically study per week is between zero and 168 hours.
Hours is a predictor variable, because it is believed/assumed to influence the outcome of the study.
Dependent variable: Final exam score.
Final exam scores is a discrete variable as reported, although it could be a continuous variable with a value…… [Read More]
List the research question for the study. The researcher is interested in looking at whether or not an appraisal from a person's manager regarding their job performance affects the person's self-esteem as measures on a self-esteem appraisal survey (SEM). According to the vignette while the researcher has managers give either a positive rating or a negative rating; he/she has no pre-experimental hypotheses regarding of how these specific appraisals will affect self-esteem (other than appraisals may affect self-esteem) and therefore the directionality of positive or negative ratings does not appear to be important in terms of the hypothesis.
Ma = Mb (Here the researcher is interested in the change on a measure of self-esteem from pre-to post intervention). Note to Customer: I'm using M. To represent mean here; it would also be correct to use the variance of the groups).

Number of Siblings
The histogram for the number of siblings shows a negatively skewed data set, with more participants reporting fewer siblings. However, the range in this variable was quite high, ranging from 0 to 22 siblings. The mean response was 3.71 siblings, the median response was 3 siblings and the mode of the sample was 2, indicating that the most frequent response was 2 siblings. In this case the mode would likely be a good representation of this sample, as it represents the majority. The mean could also be used as a way of representing the number of participants who did have more than 2 participants, but outliers, such as the individuals reporting more than 15 siblings, heavily influence the mean. After the scale reaches approximately 10 siblings, very few individuals endorse responses higher,…… [Read More]

In the first and second years of the study, students in all three groups are monitored to assess the number…… [Read More]
1. What are the null and alternative hypotheses?
Null Hypothesis: Volume has no relation to defect rate (the slope is equal to 0).
Alternative Hypothesis: As volume increase, defect rate increases. (the slope is not equal to 0).
2. What is the population of interest? What is the sample?
All shifts at the plant in question make up the population of interest.
160 randomly selected shifts make up the sample.
3. On the basis of the output, what can you conclude about the null hypothesis?
The null hypothesis can be rejected. There is a significant linear regression between volume and defect rate and the slope is not equal to 0.

H1: Females are more likely than males to have ever smoked a cigarette.
This hypothesis is not supported by the data. In this sample, 34.7% of those who had ever tried a cigarette were male, while 32.3% of those who had ever tried a cigarette were female.
H2: Males are more likely than females to have ever used cocaine.
This hypothesis is supported by the data. Of those who had ever tried cocaine, 13.9% were male and 8.6% were female.
For all of the drugs included in this survey, males made up a larger percentage than females in the group that reported having used each drug. Given that the sample has slightly more females than males overall, this finding emphasizes that men are more likely than women to have tried a wide range…… [Read More]

During the training, participants learned various techniques for decreasing their stress levels. All participants were given a life stress test to determine their current level of life stress. Scores on the test were labeled as either high or low. After a week, all participants were given a puzzle to put together in a stressful environment (e.g., loud noises, bright lights, etc.). The amount of the puzzle completed in the time frame of 5 minutes was measured according to the number of pieces completed (there were 10 pieces to the puzzle).

How did you treat missing or oddly coded data, and outliers?
The SPSS function for Missing Data was used to identify any outliers or oddly coded data. The percent of missing data is high at 47.2% or 1063 potential responses to the question. The number of extremes or outliers in the high range is 220. Because the numbers are high, it would be useful to look at the raw data to determine how these answers were coded. This question is an interesting one and the pattern of responses suggests that additional analysis with this variable could reveal relationships with other factors.

statistical test (SPSS Output) is effective as far as it goes in this particular case, but the results are not as clear as what they could be. A number of variables were used to generate results that on the surface were easily defined but a more analytical approach shows that the results could be much more comprehensive. The variables included three groups; low, medium and high scores depending on the respondent's answers to 10 questions. Additional variables included the gender of the respondent as well as the number of respondents in each category. Other variables could include the questions themselves and how the questions were written. Since there were only ten total questions, the validity and reliability of the questionnaire are two unspoken variables that should have been addressed.

GPA is interval level data one can report all measures of central tendency and dispersion (Creswell, 2012). In the original data case 38 had a GPA reported as 9.00. This value is of course impossible and since there were no missing values defined in the data set this case was treated as missing data. If used as reported it would have resulted in a much larger standard deviation and slightly larger mean for the calculations. The mean GPA of the sample was 3.2941. The median GPA was 3.2750 with a mode of 4.00. The standard deviation was .50644 (with the miscoded value the standard deviation would be .82215). The range for GPA in the sample was 2.00 with a minimum value of 2.00 and a maximum value of 4.00 (including the miscoded value would inflate the range to seven).

Correlation & Regression
A fifth grade science teacher wants to know if there is a relationship between final exam scores and overall coursepoints after adjusting for a quiz score.
In order to determine whether there was a significant relationship between overall coursepoints and final exam scores, after controlling for quiz scores, a hierarchical regression was run. All assumptions were assessed using SPSS. There was independences of residuals, as assessed by a Durbin-Watson statistic of 1.08. An examination of various scatterplots indicated a general linear relationship between variables of interest, although perfect linearity was not observed.

*Two literature searches were conducted in order to generate conditions of nurse satisfaction. One search centered on variables of work satisfaction described in relevant job satisfaction theories. The other search probed applicable reviews and meta-analysis for factors of job satisfaction relevant to the nurse profession.
The literature, in the first case, was plumbed for studies that provided theoretical insight into the concept of job satisfaction. Terms such as 'job satisfaction' and 'theory' were used to aid the research.
In the second case, research was conducted by using terms such as 'nursing', 'job satisfaction' and 'factors'. The resulting Meta analyses and literature reviews were thoroughly analyzed and only those relevant to the intent of the study retained. They had to, in other words, be congruent to the nursing profession and related to satisfaction that the employee gained from his or her job.
'Nurse satisfaction' as a result was,…… [Read More]

colloquially individuals may think that some people are smarter than others, the more scientific term for the concept of being smart is intelligence. The notion of measuring a person's intelligence was first pursued in the early 1900s by Alfred Binet (Kamin, 1995). The French government was looking for a way in which to help predict which students would have the most difficulty in school (Kamin, 1995), so they hired Alfred Binet, who was a psychologist, to develop a test. Binet developed the first intelligence test, a version of which is still used today (Kamin, 1995). Intelligence testing really took off during World War I, when the U.S. army wanted a way to screen a high number of army recruits. This lead to the development of new forms of intelligence tests in order to determine which army recruits were of a higher intelligence and would be successfully in leadership roles (McGuire,…… [Read More]

The role of leadership styles and their applicability to the success or failure of mergers, acquisitions and alliances is the focus of this research. Any leadership study, to be relevant, must also focus on the needs of those served by the organizations studies. That is why in the proposed Change Management Equilibrium Model have customer-driven processes at their center or core. The focus of the research to either validate or refute the model is based on consistency and collaboration as two factors that also serve to create greater levels of integration between the two or more healthcare providers merging or changing their organizational structures to better serve the market. This market orientation is what many public-ally-owned and operated healthcare providers struggle with, as often the source of funding becomes their "customer" or whom they serve (Brinkmann, O'Brien, 2010).

Figure 6 represents the cross-tabulation of religious service attendance with x-rated movie viewing. In this analysis, it is interesting to observe that weekly church attendance may "inoculate" respondents against watching an x-rated movie, but that no other level of religious involvement has a particular influence on porn consumption. Of the respondents who have seen an x-rated motive in the past year, their religious service attendance patterns follow the same trend as respondents who claim not to have seen an x-rated movie in the past year, with the glaring exception of those who report weekly attendance. This seems to be another case of regression to the mean, in which a socially normative response (weekly church or temple attendance) overwhelms useful data and obscures a potentially interesting correlation.

Differences in opinions between various study groups are expected to become apparent. These differences will help to determine the amount of bias present in opinions regarding housing discrimination among non-Irish nationals. Interpretation of these hypotheses will depend on the consistencies in opinion found between various groups.
The hypotheses will help to determine if the opinions of various groups in Dublin are biased. However, in order to gain a deeper understanding of the concepts being examined, the following research questions will also be explored, in addition to the hypotheses. These research questions will be addressed through specific sets of survey questions.
1. Are there differences in opinion regarding the quality of housing between Irish and non-Irish nationals living in Dublin?
2. Are non-Irish nationals well educated, at least as much as the Irish national population in Ireland?

Some researchers have suggested that there are two main types of personality: Type A and Type B. Individuals with Type A personality are characterized as being conscientious and competitive. They strongly desire success and typically present with higher levels of stress. Conversely, individuals with Type B personality are typically less stressed and tend to be more laconic, relaxed and less concerned with competition.
Due to the higher levels of stress experienced by those with Type A personality, health insurance risk evaluators are interested in knowing whether individuals with Type A personality are at greater risk of having a heart attack.

egression vs. correlation?
Correlation is used to test whether two variables covary, the strength of the relationship, and the direction of the association. A correlation calculation will generate a P-value and a correlation coefficient (r). By comparison, regression will generate the slope and intercept for a best-fit line that can be used to predict unknown values for the dependent variable.

Walker & Staton also stress that all of the aspects of cultural competency that are understood, should be applied through systems that are sensitive to such needs.
As a quality of empathy, cultural sensitivity is not testable as content, but it can be an expectation of practice in the same sense that integrity or justice can be. The desirable posture for the social worker is one of cultural agnosticism -- not trusting in any particular cultural mold (the social worker's or the client's) to determine what is right, wrong, or ultimately meaningful (Sue, 1998). (Walker & Staton, 2000, p. 449)

The dependent variables in this study will be the scope of wife beating and the causal factors that contribute to it. Questions five through nine on the survey address these variables. In order to evaluate perceptions of scope, the author asks participants to estimate the prevalence of domestic violence in the U.S. population. Four options are provided for how many men beat their wives in the aforementioned population: 1/10, 1/50, 1/100 and 1/500. The participant is asked to check one.
The causal factors for domestic violence listed in the survey (questions 6-9) are drug and alcohol use, mental or personality issues, and cultural differences. These factors emerged as the most influential in predicting the prevalence of domestic violence in the reviewed literature. The survey addresses cultural, socioeconomic and behavioral characteristics of relationships that were repeatedly shown to influence the scope of domestic violence (see literature review). The participants are asked…… [Read More]
In other words, when the total number of people characterized by each variable (or stratum) oscillates within the population, to the researcher would choose the size of each sample for each stratum according to the research requirements. uch a choice is prejudiced by the probability of obtaining an adequate number of sampling units from each stratum within the final sample. As a rule, disproportionate stratified samples are used either to compare two or more particular strata or to analyze one stratum intensively (Creswell, 1994). Therefore, when researchers use a disproportionate stratified sample, we have to weight the estimates of the population's parameters by the number of units belonging to each stratum. In this sample, weighting strategies were not performed in the original data.
Once researchers have defined the population of interest, they draw a sample that adequately represents that population. The actual procedure involves selecting a sample from a sampling…… [Read More]
Employment Discrimination at Wal-Mart
Foundation of the Study
This study examines the legislative and judicial climate that enables corporations like Wal-Mart to engage in practices that violate workers' rights. The popular consensus is that Wal-Mart, the largest retail store in the United States, displays an inordinate disregard for the human dignity and morale of its employees and, despite continual litigation, continues to blatantly violate the legal rights of its employees. Wal-Mart faces charges of violating The Federal Fair Labor Standards Act (2011) by asking management to adjust time sheets so that overtime will not need to be paid, and so that all employees will work under the hourly limit required by the union in order to obtain membership. Employees were insured, without their knowledge, against their death by Wal-Mart. The company was named beneficiary; following death of an employee, the entire benefit amount was retained by the corporation. Not a…… [Read More]
Social Anxiety Questionnaire: A New Scale to Measure Social Phobia
Social anxiety or social phobia is the most common anxiety disorder and affects millions of Americans. The effects of social anxiety can be quite devastating. There are several scales that have been developed to assess social anxiety in people, but there are few scales that consist of less than 20 items. The Social Anxiety Questionnaire, a 14-item scale to measure social anxiety, was tested on 89 college students and compared to the Social Interaction Anxiety Scale (Mattick & Clarke, 1998) and Eysenck's Introversion Scale (Eysenck. 1970; 1971) for validity. The psychometric properties of the scale, future directions for research, and practical applications of the scale are discussed.

Conversely, the Jordan tourism industry has demonstrated poor performance in past few years relative to the volatile political situation in the region.
Analyzing both the natural potential for success and the historical evidence for failure within Jordan's tourism industry through scientific research methodology may well provide viable alternatives to current widely held practices and beliefs.
This study will delve into the specific revenue producing areas of developing conferences in Jordan, how to conduct them, facility use and maximization, and the issues that surround successful delivery of this medium. This thesis will also provide data on the means of offering the world a safe, beautiful, and…… [Read More]
complexities of doing business in our virtual age, looking in particular at e-commerce but also asking how the presence of e-commerce on the market has affected traditional businesses as well. Once upon a time - that golden age - things were simple. You decided you wanted to grow up to be a bookstore owner. Or a hardware store manager. Or a florist. So you leased a store, bought some books, and lovingly hand-sold them to each customer who flocked to your door and then went home at night to count your money.
Of course, owning a bookstore or a hardware store or a flower shop was actually never that simple. But the picture now is even more complicated as virtual stores have entered the picture. Part of what makes engaging in e-commerce so difficult is that there are no paths that others have trod before one. And the costs of…… [Read More]
ole in the group
Working with other people can often present its own share of challenges. Thus, far in doing this social sciences research, I have indeed found this to be true. My previous experience working with this group has been an experience of growth and development, though not without its share of challenges. These challenges have only succeeded in making me stronger and more communicative with others. This paper represents a reflection on the latest experience I have had collaborating with the other members of my group and what I learned.
For this group, I participated in assisting with the questions used for the survey and the use of the spss program to construct the survey. The process was largely extremely satisfying for me, and as I gathered, for nearly all members of the group at large.
I felt that I was able to effectively motivate others. Whenever we…… [Read More]
Good researchers tend to pull methods out of a tool kit as they are needed" (2006, p. 54). Notwithstanding these criticisms and constraints, though, most social researchers seem to agree that classification by some type of research paradigm is a useful approach based on the need to determine which approach is best suited for a given research enterprise. In this regard, Corby concludes that, "The contested nature of research makes it impossible and unhelpful to ignore the different aims and purposes of various research projects and the methods and approaches being used to carry them out" (2006, p. 54). Therefore, the different aims and purposes of the positivist research paradigm, the constructivist research paradigm and the pragmatic research paradigm are discussed further below.
Positivist Research Paradigm
The positivist research paradigm is a quantitative-based approach that generally seeks to identify trends and patterns that can be used to formulate predictions concerning…… [Read More]
web-based surveys and their usefulness in reducing the cost of business research. The writer explores several aspects of web-based surveys including performance and comparison to traditional type surveys. There were 10 sources used to complete this paper.
There are many reasons that people gather information today. ealth professionals gather information to help determine health trends, needs and problems. Marketing professionals gather information so that the consumer can be better served. Churches gather information to better provide for the spiritual needs of the public. Law enforcement officials gather information to ascertain crime trends as well as other information that is useful for predictions and budgeting needs. Different sized governments gather information for the purpose of providing public services to those who live within their geographic area as well as estimations and predictions about the future of the area. There are many reasons to gather information and there are very few instances…… [Read More]

Types of Hotels
The U.S. Department of Labour (2004) denotes five basic types of hotels:
Commercial - These hotels operate year round and are primarily located in cities or suburban places. The larger properties offer an assortment of services for their guests, such as coffee shops, restaurants, cocktail lounges, gift shops, newsstands, theatre, health spas, swimming pools, etc.. Even larger hotels offer banquet rooms, ballrooms to accommodate wedding receptions; business meetings. Convention and business meetings provide major sources of revenue for larger hotels
esort - These hotels are primarily located in vacation destinations near mountains, the seashore, or other attractions. Nowadays, some resorts provide additional convention and conference facilities to stimulate their customers to combine business with pleasure. (U.S. Department of Labour, 2004)
esidential - These establishments provide a…… [Read More]
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.

Measurement and Instruments for a Quantitative Research Plan: Human Trafficking
For a study into human trafficking and how many people end up being trafficked every year, quantitative measurement is necessary. Qualitative methods could be used, but they would be better suited toward providing insight into the feelings of those who were trafficked, as opposed to the prevalence of the trafficking problem itself (Creswell, 2003; Given, 2008). Since there are several options and ways this issue can be measured, it is important to decide not only what type of measuring instrument will be used but the level of measurement that is really important for the study (Bales, 2004).
Human trafficking can be very difficult to measure, based on the secretive nature of much of it and the unwillingness of traffickers (and many victims) to talk about the issue (Bales, 2004; Berger, 2012). However, that does not mean there is no way…… [Read More]

Describe ways in which MS Excel can be used by a manager of an organization as a tool for interpreting data
There are different ways in which a manager of an organization can employ MS Excel as a tool for data interpretation. One of the uses of MS Excel is collating, which encompasses collecting associated data items into a single item. The layout and formatting of the worksheet can enable the managers to perceive data sets in a structured and organized formation, which augments clarity of the data. The second benefit is processing. Excel cells can include functions, formulas as well as references to other excel cells, that permit one to glean information in prevailing data sets. Therefore, excel functions can facilitate the process of interpreting a data set in a manner that is suitable to the data itself and the system in position.…… [Read More]

The main feature of my viewpoint concerning the importance of being an IT manager that has been changed following the readings and interactions with others has been just how essential the IT manager position is to the success of companies of all types and sizes. An army may move on its stomach, but it is reasonable to suggest that many companies today move on their information technology resources. In this regard, Jia, eich and Pearson emphasize that, "The role of the IT function within the organization has expanded considerably in recent years, driven by changing expectations from business and the evolving technological environment" (2008, p. 294). Therefore, a responsive and well informed information technology manager can therefore contribute to the difference between success (and failure) of their enterprises in ways that have never been possible in the past (Desai, Hart & ichards, 2009). In fact, Jia and her associates (2008)…… [Read More]

Health Care Improvements
The health care industry is one that is much criticized in the United States. Many consumers look at this industry as one big giant industry that is only concerned about profitability, not about the health and safety of its customers. The health care industry must make many changes to change their image and provide better service to its customers. Medicare is a government health care insurance that covers 80% of the medical cost for individuals over the age of 65 years. Medicare currently has a bad reputation with its customers and with doctors. It is important for Medicare to change its reputation and build better relationship with customers and with doctors. By changing their image, Medicare will attract more doctors to become participants and this will be a better service for the customers. In this paper I will address some important steps that Medicare could take to…… [Read More]
T-tests in Quantitative Doctoral Business Research
Quantitative research is one of the methodologies that is commonly used in doctoral business research. The use of this approach is attributable to the availability of more data that requires analysis to help generate competitive advantage in the business field. The use of quantitative research entails conducting statistical analysis, which involves the use of different methods such as t-tests and ANOVA. T-test is used in hypothesis testing in quantitative studies to determine whether variations between the averages of two groups is unlikely to have emerged because of a random chance in selection of a sample. In essence, t-tests help to compare whether two groups have varying average values. In light of the role and significance of the assumptions underlying each parametric test, this paper provides a comparison of one-sample, paired-samples, and independent-sample t-tests within the context of quantitative doctoral business research. The comparison is…… [Read More]
tests (CTs) and scales vs. norm-eferenced
Criterion-referenced tests (CTs) are often the preferred method of assessing the performance of many practitioners in the healthcare and 'helping' professions such as nursing. An example of a criterion-based objective is that a student mastered 90% of the terms on a particular test (McDonald 2002). The NCLEX (National Council Licensure Examination) for nurses is an example of such a test: all nurses that pass the test can obtain licensure. The test is deemed to be both reliable and valid. "The reliability of the NCLEX examination is assessed via a decision consistency statistic. This statistic is used instead of a traditional reliability statistic such as Cronbach's alpha because it captures the reliability of dichotomous pass/fail decisions rather than the reliability of continuous scores or ability estimates" (eliability of NCLEX, 2013, NCSBN: 2).
In terms of the NCLE, the exam attempts to ensure content validity; face…… [Read More]
Thirty undergraduate students will be recruited to participate in this study. At least one student will represent each of the University academic departments. They will be recruited via Ashford University Facebook group. Most of the students are active Facebook users. So, a post inviting volunteers to participate in this study will be read by majority of the students. Each participant will be compensated because they are expected to attend two different sessions. The study will be carried out according to the ethical standards set by Ashford University.
All the participants will fill an informed consent form. The form will tell participants that they are participating in a study about temperament and creativity and their responses will not be used for any other purposes apart from this study.
Torrance Tests of Creative Thinking (TTCT) and Formal Characteristics of Behavior - Temperament Inventory (FCB-TI) questionnaire will be administered…… [Read More]
Humans faces numerous challenges arising from majorly stress and conflicts in life that interferes with them in one way or the other. These daily predicaments cause one to be temperamental. Temperament is a state where an individual’s behavior and emotions show anger (Drabick and Ribanowitz, 2017). Such altered emotions and actions deprive one sense of focus, reasoning rationally and even having a decorum behavior. Researchers notes that temper is on the rise among children and adolescent individuals and as such it is becoming a major problem (Schimmel and Jacobs, 2011).Anger at time becomes chronic that one destroys things ,physical and verbal abuse ensues, unruly behavior and sometimes leads to suicide or homicide .For instance, Robin Williams, the famous Hollywood actor ,committed suicide out of depression.
In as much as there is considerable level of negative effect of anger, there is certain degree of anger that can…… [Read More]
Once this data is captured, the third objective of building an equilibrium-based model that conceptually defines the relationship of companies who chose to invest from a strategy standpoint over those that were functionally-driven and the differences in profitability as a result. This model will also be used as the basis of creating a four-step maturity model that will attempt to show how over time strategy-based implementations are more effective at creating collaboration within and between firms choosing this approach.
The most significant benefit of this study is determining what factors contribute to the success or failure of CM systems, taking into account implementation planning and strategies to mitigate resistance to change. The success or failure of CM system implementations is often with the area of change management and alignment of these systems to business strategies (Foss, Stone, Ekinci, 2008). The proposed research will show through an equilibrium model and…… [Read More]
