Treatment of Data and Hypothesis in esearch
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…

A null hypothesis is what is being tested. Essentially, when one runs a statistical test, the objective of the test is to prove the null hypothesis. If the null hypothesis is not proved, then the alternative hypothesis is proved. A good example of this would be trying to test drinking water from a well to prove that it is safe. Let's say that the cutoff for safety is 100 parts per million of a specific element. We cannot tell by looking at it whether or not the water is safe, so we must test it. The null hypothesis is that the water is safe; in other words the null hypothesis is that the water will have under 100 ppm of the element. We run the test on the water and it shows 140 ppm.
This means that the null hypothesis was not proven -- the 140 ppm is higher…
What types of research question(s) can best be addressed through the use of case studies? What are the advantages and disadvantages of the case study approach?
The case study approach is favored in many research studies in the social sciences, particularly sociology and anthropology. Case studies are useful in examining questions about a particular social group, and also explain phenomena with multiple causes, such as 'juvenile delinquency.' Finding ways to treat this sociological problem requires viewing particular types of juvenile delinquency in a sociological context, examining familial and social data as it relates to the behavior, and assessing how, for example, urban delinquency is different from 'small town' delinquency or how delinquency is practiced or viewed differently by various ethnic, racial, and religious subgroups. The question 'do female gang members in urban locations exhibit less violent criminal behavior than their male counterparts' might be a useful case…
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…

If they can bench-press heavy weights, they may emphasize athletics at the expense of academics, in terms of how they prioritize their time. However, it is equally possible that in some schools, high-achieving students also use athletics as a way of bolstering their college resume. Factors such as the school, the degree to which athletics makes demands upon student athletes within the particular environment, and the intelligence of the players may indicate there is no correlation.
Daily air temperature & the average weight of clothing worn
H1: There is a negative correlation between temperature and weight of clothing -- in other words, greater the air temperature, the lighter the clothing.
H0: There is no correlation between temperature and weight of clothing.
Estimate: Negative correlation -1
Analysis: The research hypothesis is likely to be proven, with only small variations for such factors as rain and humidity.

The author of this report has been asked to answer three broad questions about certain statistical terms and concepts. The first one of those will be standard deviation. The second of the three will be hypothesis testing. The final question will center on standard error and what it means. While statistics may be daunting and intimidating, the concepts and terms used in statistics parlance are not hard to understand or comprehend so long as they are explained and quantified carefully.
The first overall question is what precisely standard deviation happens to be. To put it simply, standard deviation is how dispersed a set of numbers are. For example, the numbers 1, 2 and 3 are very close together so the standard deviation value would be rather small. However, the numbers 1, 1000 and 1,000,000 would have a very large standard deviation because the overall range of the numbers…

To test whether the research results are statistically significant an appropriate test of statistical significance should be run. A chi-square "goodness-of-fit test is used to determine whether a set of proportions have specified numerical values" (Hypothesis testing, 2009, Quick MBA). However, in this specific instance, since it is likely that multiple batch tests for defects will be run, an ANOVA test would be more appropriate: "The primary purpose of ANOVA is to test for differences between multiple means. Whereas the t-test can be used to compare two means, ANOVA is needed to compare three or more means. If multiple t-tests were applied, the probability of a TYPE I error (rejecting a true null hypothesis) increases as the number of comparisons increases" (Hypothesis testing, 2009, Quick MBA). A one-way ANOVA examines whether multiple means differ. "ANOVA calculates the ratio of the variation between groups to the variation within groups" (Hypothesis testing,…

Efficient Market Hypothesis
As previously discussed, the weak form efficiency suggests that share prices should follow a random walk, in that each change in share price is unpredictable based on past information. Formally, this is expressed in the following relationship:
where the variables are independent and identically distributed random variables representing equity prices at times 1,2,3…,k. So X is the equity price, the equity price at a point in time n and the change in equity price at any given time is not explained by the past equity price.
The augmented Dickey-Fuller test considers the following model:
where p is the lag order of the process which can be determined by the examination of autocorrelation and autocorrelation plots, and are the factors determined by the regression. The unit root test has the null hypothesis, and the rejection of the null hypothesis implies that the time series is stationary. The variable…

Technical Analysis in the Implication of Efficient Market Hypothesis on Silver Market
The thesis is for the study of simple commonly used technical trading rules, which are applied on silver market. It covers years 1989 to 2005. A famous study carried out by Lakonishok, Lebaon and in year, 1992 has clearly shown that technical analysis can lead to abnormal prices when compared with buy-and-hold strategy. Other studies have been carried out and found out that technical trading rules cannot over-rule passive investment management strategy. The study uses Brock et al.'s methodology. Several trading rules are discussed (Dawson & Steeley 2003).
In financial theory, efficiency of financial silver market is highly disputed. This has led to many attempts to explain efficiency of silver markets. Eugene.F.

Ultra violet light affects many people, and several experiments may be done to either support or disapprove the hypothesis. Approval of the hypothesis forms a theory that people who are highly exposed to ultra violet light have higher chances of getting skin cancer. Theories on some scientific approach may serve as sources for theories. Observation of people's behavior may lead to development of hypothesis. This includes looking at how people dress during certain times or what they do at certain times of the year. esults obtained over a research or experiment may lead to development of a theory. Experience of the scientists in their work may be a source of hypothesis and theory. Many things happen around that nobody can explain them scientifically.

Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability
This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be the best solution to climate change. Given the threat posed by climate change, it makes sense that nuclear power would be increasing in share, not decreasing. This esearch proposal seeks to look at some of the issues facing nuclear power, and how it can overcome these issues to increase share going forward.

Tips on Understanding and emembering the Three Types of Hypotheses
The three types of hypotheses can seem confusing at first, so it is helpful to devise tips for understanding and remembering their differences. The three hypotheses -- null, nondirectional and directional -- can best be described in the following terse manner: null means no relationship between variables; nondirectional means that there is a relationship or difference between variables but the hypothesis is not concerned with the outcome of the relationship/difference -- only with the fact that the relationship/difference exists; and directions means that the outcome is important to the hypothesis. To put it even more simply, null means no relationship/difference; nondirectional means relationship/difference; directional means outcome of relationship/difference (Elwell, 2013).
The tips to remembering these three types of hypotheses can include spending time examining many different examples of hypotheses and identifying their type. For instance, the resource text provides examples…

Gall states sampling strategies like these may be incompletely accurate due to the verbal data given and artifacts researched. it's never 100% accurate, the sampling, due to the fact the data is gathered through verbal, at times, unproven means. Levin names certain strategies that could easily be devoid of accuracy due to researcher's lack of funds.

Perceptions of sustainability improved slightly in the experimental group, however this change was not significant and the null hypothesis is not rejected (p=.32). The flag exposure did not improve perceptions of sustainability to a noteworthy degree.
Once more, there was statistically significant change -- and once more, it was so significant that the null hypothesis would be almost certainly rejected (p-value is effectively 0) -- but that this change was again in the wrong direction. Flag perception (or possibly the confounding variable of healthy eating desires, though that seems far less likely for this item) is correlated with a significant decrease in perceptions of traditionality, not an increase as predicted in the alternative hypothesis. The null hypothesis remains in place, therefore.
With one confounding variable between the groups, the examination of the given experimental variable (i.e. The inclusion of the flag on the product image) and its…
Given that hypothesis testing holds the potential to provide keen business insights, the question that immediately arises is 'how does one conducts a hypothesis test?' It is a five step process.
1. First we formulate the null hypothesis (Ho), the statement or claim that will be tested. Using our earlier widget example, the null hypothesis (Ho) would be "Productivity is low in the widget making department because morale is low" (Bushman, 2007).
2. Next we formulate the alternative hypothesis (Ha), the exact opposite of the null hypothesis. The alternative hypothesis (Ha) would be "productivity is unrelated to morale."
3. We then identify a test statistic that can be used to measure the truth of the null hypothesis (more on this shortly).
4. We determine the P-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis…
To define the safety objectives of the UAV, it is essential to evaluate the current level of safety necessary for the human-piloted aircrafts. While manned pilot aircrafts consider the safety of the pilots and the people on board to be important, however, the safety of the UAV is considered relatively to the hazard that that it will cost to the community. Thus, the intervention of human related aviation safety is still critical to enhance overall safety of the UAV. Although, the UAV accidents may lead to the zero loss of pilot's life, nevertheless, the financial investments that the governments or private organizations provide for the development of the UAV is huge, and the implementation of maximum safety to realize the objective of UAV is very essential. The human related aviation safety is still essential.

Analysis of Variance (ANOVA)
Analysis of variance is a term used in statistics which involves a collection of statistical models and procedures that are associated with them where the observed variance in a particular variable is partitioned into components that can be attributed to different sources of variations. It is therefore a statistical technique that is useful for evaluation whether there are differences between average values or mean across several population groups. This model also entails that the response variable is continuous in nature while the predictor variables can be categorized. For there to be a test for statistical significance between means then there has to be a comparison i.e. analyzing variances hence the name of the model. There are various concepts in variance analysis these are; the partitioning of sums of squares .at the core of variance analysis is the fact that variances can be divided or…

Therefore, the research showed that "many organizations within it industries focus on providing "extensive retraining of employees," especially "as reengineering efforts go forward it is important to define and redefine performance goals and objectives, maintain a strong commitment to the vision, break the barriers between the departments, and be flexible as the business environment changes."

teacher instructional technology with new literacy instruction to improve elementary (K-5) student achievement in reading vocabulary?
The alternative hypothesis would be that new literacy instruction does have th potential to improve elementary (K-5) student achievement in reading vocabulary. In other words that significant difference is found between classrooms that employ new literacy instructions and classrooms that do not use this method.
The null hypothesis would be that no significant difference is found between classrooms that employ new literacy instructions and classrooms that do not use this method.
The study will choose 2 different schools in a certain district with classes k-5 where one school has introduced new literacy techniques (namely technological strategies), and the other school is still employing traditional instruction.

In the research question given in question 5, two variable types can be identified. These include the dependent and the independent variables. According to Hughes & Hayhoe (2007), the independent variable includes the intervention to be tested while the dependent variable essentially comprises of the result to be measured. In the research question outlined in question 5, the independent variable is caring for a pet. On the other hand, we have the dependent variable being the lifespan of a person over 65 to 75. According to McBurney and White (2009), the effects of the independent variable are reflected or mirrored on the dependent variable. In our case, caring for a pet which is the dependent variable can be said to be a measure of the behavior of the subject.

Second, the researcher's intense exposure to study of a case can bias the findings (the case study as a research method); at the least, there are significant opportunities for subjectivity in the implementation, presentation, and evaluation of case study research (Case studies). This high degree of subjectivity opens the door for ethical issues, particularly if the study is being sponsored by a special interest. Third, case studies involve too much investment of time and money to be appropriate for large-scale research projects (Case studies).

Standard deviation is a measure of how far the data is spread from the mean, and can be used to assess the accuracy of the sample mean.
Type I errors are improper rejections of the null hypothesis.
Type II errors are failures to reject the null hypothesis hen it should be rejected.
Level of Significance measures the likelihood of committing a Type I error.
Power analysis measures the risk of committing a Type II error.
Regression analysis measures the relationship between two groups, and can be used to compare separate groups or the same group after an intervention. There are several ways to perform regression analysis.
Analysis of variance (ANOVA) measures the variance observed in groups of data and works to attribute observed variances to specific observed variables. There are different tests used to perform analysis depending on the type of data available and the desired information output.

The mean difference of the sample from the test value of 100 (the average of the general population) was 29.25, with confidence intervals of 24.9 and 33.6, indicating that there is a 95% level of certainty that the true mean difference lies between these two numbers.

The focus of this proposal is to use the analysis of variance (ANOVA) to test whether the video games influence behavior. There has been a general public concern on the risk factor of video games on the youth's behavior especially children under 18 years of age. Science Daily (2013) shows that video games are the risk factors to aggression and criminal behavior. Despite this assertion, there still a paucity of valid and reliable academic research on the risk factors of video games on behavior. This proposal attempts to fill the gap by using ANOVA to test whether the video games influence behavior.
Do video games influence the aggressive or criminal behavior?
ANOVA is an appropriate statistical test for the proposal because it will be used to test for a significant difference of two means. Using the ANOVA for the proposal, the researcher will be able to produce valid…

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…

Cloning has been a hot issue in the news media in recent years. Many feel that it is a good idea and that there could be many benefits to mankind. However, there are those who feel that the issue is beyond our human capabilities and that we are playing with fire. There have been many surveys conducted on public opinion concerning the issue. Some of the studies have been formal, conducted by the research community, and others are informal, conducted by parties such as the news media. Many of these studies failed to separate answers according to gender, age and other demographic issues. Not knowing the demographics of the sample population and taking into account the number of members in each demographic group could essentially add sample bias to the answers.

The exam though it's validity as a barometer for academic preparedness for higher learning is contested, is a means of examining the factors which have been shown to be directly related to the outcomes seen with this strategy. Block scheduling has been shown to correlate directly to mathematics, language, and critical thinking in terms of improving scores. Also, the application of this evaluative comparison across a variety of students and academic settings may resolve the existing questions regarding the relative failure of an otherwise successful technique to raise writing skills. The test will be administered at the conclusion of each trial period in the fashion it would be administered in its intended use. The scores of each student will be compared with their previous score. The overall bell curve of scores between conditions will also be compared as a means of determining both specific and general efficacy.

Z Test in Psychology
Stating the research question
The z test is being used to test whether watching a film about the conditions of institutionalized mentally ill patients will influence viewers' attitude towards the mentally ill. Evaluations are accomplished using a questionnaire and the scores for viewers and non-viewers will be compared using the z test.
The test subjects are students. The variable being tested by the z test is the mean scores obtained by the two groups on the survey instrument. The scores represent discrete numerical data. The z test will compare the survey score distributions between the two groups: viewers and non-viewers.
Specifying the null and alternative hypotheses
The null hypothesis (H0) for this experiment is that the mean survey scores of the two groups, viewers and non-viewers, will not be significantly different using the probability cutoff value of 0.05 (alpha). The alternative hypothesis (HA) is that the…

ecession and the Performance of Banking Industry
ecession worked negatively on the banking industry especially so because the industry was still at its initial growth stage. The industry has reformed and change significantly following changes in observed. The data analyzed is expected to show how much recession influenced the changes in policy and regulations. It will also show that banks had a lesson to learn as far as the economic performance and trends were concerned. To date, given the trends banking industry are seen as most susceptible to the economic downturn and the key resolving this is to make changes as a safe guard measures. This is expected to come out in the data analyzed showing the existence of policy and operation changes and strategies adopted in light of economic performance.

Employee Satisfaction with a Company's Review Process
The following research examines the reason for a decline in employee satisfaction regarding the review process at XYZ, Inc. The results of the survey revealed that sample biases may have confounded the results and that the survey will have to be re-administered to reflect the true attitudes and results of the preliminary research leading up to the current survey. The result showed a high degree of satisfaction with the quality and quantity of management feedback. The results of this survey are inconclusive and further research will need to be conducted to eliminate the possible effects of sample bias.

The increase in teen smoking may be abating, or may be taking a pause before it continues the climb seen in the past 10 years, from 1996 to 2005. In either case, reducing smoking at an early age has a lifelong effect on individuals' health, and can lead to better quality of life for millions of people who might otherwise take up smoking. A secondary benefit is that lessons learned may help to reduce the current 3.1 million teen smokers, many of whom try smoking and quit -- it would be useful to know why they started in the…

Explain why you are not using other methods
The method described above is the most applicable to this study since I would need a closely involved study. I would not use a quantitative experimental approach since randomization is out of the question here -- this is a convenience sample. I would also like to have a rich study that operates in a real-life situation and this cannot be studied via empirical means.
I agree with Dilthey (1954) that humans, being more flexible and diverse than objects studied in a lab (animals included), cannot and should not be 'frozen' under a 'microscope' for statistical analysis and factual conclusions. Humans, not reducible to the physical world, cannot be fissured down to discrete variables. Doing so would result in ignoring the very aspects of their humanity, consequently leading to erroneous conclusions.

The committee believes that in order to successfully offer archery and fencing as sports in the community program, these level-of-difficulty and social-psychological concerns about the two possible sport offerings must be understood. Obviously, the study of each research question above will inform the other, as both archery and fencing have had similar prestige perceptions in the general public for decades (See for example, Crawford, 1977; and Riess, 1980).

Since the beginning of time the male species has had an obsession with that part of the personal anatomy known by its Latin root as the "tail"; or today known as one's pecker, "wankie," monkey, and a host of other rather humorous titles. Somewhere, however, in creating the world God must have became confused when creating man as, and being politically correct, he/she placed the tail on the man's front side and on the animals' rear side -- or maybe God just had a bad day on his/her day of creation. Regardless of what one wants to call his penis or tail, history has proven that man's obsession with the penis is ever ending. Simply consider the folklore surrounding John Dillinger whose penis was reportedly over 20 inches. If medical science were correct it would likely have taken Dillinger 20 minutes to get enough blood circulating in his penis…

Certainly, there is no one best way to ensure that either employees or managers are properly motivated. Most scholarship, in fact, indicates that motivation is a balance between the task-relevant behavior and the maturity and acumen of the group in which the individual manages or participates in. In fact, motivation is the basic driving force that helps individuals work, change and actualize to achieve their goals. This motivational behavior may be intrinsic or extrinsic, depending upon the individual and the manner in which that individual's personality uses different sets of motivation to incur actualization. Much of the basic theory of motivation tends to be based on the work of Benjamin Maslow, not only on human needs, but on the manner in which those…

The null hypothesis of the research endeavor is that online professors will report no perceptible connection between post-tenure review and job performance.
The alternate hypothesis of the research endeavor is that online professors will report that post-tenure review improves job performance.
Nature of the Study
Significance of the Study
The significance of the proposed research is based in the need for greater study of online instruction in higher education with relation to post tenure review. As with all other elements of this research process, we can initiate a discussion on the significance of the research with a reiteration of the fact that amongst educators without classification, the perspective on post-tenure review is generally hostile. This is because tenure is considered by most educators to be an important feature of the profession demanding of protection. To this end, Ceci et al. (2006) indicate that…

The question of whether TANF is working to reduce the number of teen pregnancies is inconclusive. The literature review leaves many more questions than answers.
The literature review found many conflicting results and studies that were significantly flawed. The real impact of TANF on teen pregnancies cannot be determined from the studies conducted thus far. The mass media was found to quote inconclusive findings. The body of evidence found is in need to further studies to determine the status and effects of TANF on teen pregnancy. This research will fill the gap in research by providing a reliable assessment of the impact of TANF on the ability to teen mothers to become independent and successful.

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.

How do people react in a crowd?
In the first instance, differences must be made between the various faces of the 'crowd' and operational definitions must be arrived at. As Intro to ociology defines it:
Crowds are large numbers of people in the same space at the same time. (http://freebooks.uvu.edu/OC1010/index.php/ch19-collective-behaviors.html)
The 'crowd' itself is divided into various characteristics. There is, for instance, the Conventional Crowd which a crowd that gathers for a typical event that is more routine in nature. Then you have the Expressive Crowd that gathers to express an emotion (e.g. Woodstock; the Million Man March; or the 9-11 Memorial ervices). And finally you have olidaristic Crowds that gather as an act of social unity (e.g., Breast Cancer awareness conventions). All of these are non-violent and mostly predicable in their outcome.
Other categories of crowds are the emotionally charged so-called 'Acting crowds' that have a goal or…

The following study suggests that whilst macro and micronutrients are conducive to plant growth it is water that has the greatest impact on, and is the most crucial regulator of plant growth and, when regulated, can lead to the highest growth spurt. The author of this study, therefore, wished to test the effects of a pellet, one of whose elements originated from a microorganism, powder that sourced from a microorganism, and water. The hypothesis was that whilst each would contribute to plant growth, the greatest amount of growth would emerge from the water and that even thoguh all plants in each of the other 2 studies initially received the same amount of water in their feeding / growth process, addition of water to the experimental study of the Brassica rapa would -- due to water's enhanced absorption capacities -- evidence enhanced plant growth..

Proposal for Study: Is society causing biracial children to struggle with their identity?
hen forming their identity, children seek to look, act, feel, and mimic significant people in their social environment. "In his book Youth and Identity, Erickson relates ego identity and self-esteem to racial identity. He states that ambiguous messages about one's race may place a person at risk for developing what he referred to as a 'negative identity'" (Oka, 1994, p. 3). The possibility of negative identity is a controversial topic regarding biracial children. Opponents of interracial marriage argue that interracial couples are jeopardizing the futures of their children, as there is a possibility that biracial children will not be accepted by either culture and this rejection will lead to personal problems.
Some studies have found that it is more likely for interracial children to experience difficulties related to a poor self-identity, such as gender confusion,…

U.S. technology in Thai hospitals will have a positive, negative or neutral effect on the mortality rate of patients in Thailand. U.S. hospitals currently offer patients some of the most modern and complex technology available. Patients whether at private or public facilities are very often afforded modern urgent care that reduces the likelihood of mortality from common and less common illness. The mortality ratio, or comparison of patients admitted vs. discharged in most U.S. hospitals is close to or less than 1.00 (Comaro, 2003).
In Thailand hospitals, modern technology used in community hospitals is somewhat limited and typically consists of the use of X-ay technology and ultrasound for imaging and diagnosis (Dionson, 2003). Many community hospitals currently lack the advanced technology available in U.S. hospitals that has been proven to save lives. There are several private institutions within Thailand however, that do offer more advanced technology.
However, Thai hospitals historically…

This research study will examine the impact of teachers' expectation on students' overall academic achievement. The research will be conducted at Huntington Park High School, located in the city of Huntington Park.

The ethnic backgrounds of the students consist of 98.6% Latino, 0.6% black and 0.3% white. The students of Huntington Park High School (HPHS) have not been challenged to perform to their best abilities. One of the reasons may be that the teachers perceive them as incapable and lacking motivation, and so they feel it is unfair or hopeless to expect more from the students. The subtle messages received from their teachers may make the students feel incapable of handling demanding work. This could also be a factor in the students'…

The Miranda vs. Arizona ruling has attracted notable attention to the treatment of the accused in the hands of the law. Specifically, the ruling affirmed the rights to the accused under the law and to the legal rights of the accused. The research was to reveal the degree of law enforcement lack of enforcing the Miranda rights to the accused. A questionnaire presented to four group types that have a stakeholder interest in the law enforcement and legal rights aspect of the case was distributed to determine the activity relevant to Miranda enforcement process. The findings are expected to reveal abuse within the system and a notable increase in the Miranda violations for the accused.

groups in this study are independent. Despite the fact that they were not randomly assigned to groups but were assigned based on physical sex/gender is immaterial; inclusion or exclusion in one group did not influence inclusion or exclusion in the other group in any way. As there was no matching/pairing and no influence on the inclusion/exclusion or group assignment of any participant based on the status of another participant, the groups are independent.
is the t-statistic for the Mental Health (MH) questionnaire completed by the participants. This corresponds with a p-value of 0.002. According to the Bonferroni principle, significance in this study would be indicated by a p-value of 0.0033 or lower given the alpha level of 0.05 and the fact that 15 individual measures were taken/t-tests performed (0.05/15=0.0033). As 0.002 < 0.0033, this result is significant -- the groups can be said to have a significant difference in Mental…
Landecker (2009) examines the methods of teaching by a professor at Trinity College who teaches sentence diagramming to her students. The technique is no longer a common one in English classes, so the methods of the professor are quite unique. The students, however, show great enthusiasm for the practice and are able to break down the structure of complex sentences with skill and they do so in a competitive manner as part of the professor's overall testing of their abilities: they must partake in a competitive diagramming game in which one half of the class competes against the other half and points are deducted for sentence diagramming errors. The study indicates that the method is helpful for promoting participation and enthusiasm in the classroom but its narrative structure does not provide any indication as to whether the exercises have an effect on the students' ability to craft a well-written sentence…

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…
evaluator, researcher or observer watches what takes place and then attempts to analyze the data gathered during that observation to present the findings. n experimental study attempts to provide a scenario that can be answered by conducting experiments, while a study using surveys to determine results is a survey study. Each of the methods can use quantitative, qualitative, mixed and action research methods to gather data, and each of the three basic methods will also go through a step-by-step process as it attempts to come to a conclusion.
The step-by-step process for conducting basic research encompasses a number of steps. The initiation of a research project begins with a curiosity factor. Human beings are naturally curious and questioning how and why certain things are the way they are oftentimes leads to an attempt to discern those how's and why's. Those attempts are the first step in research. n individual wishes…

In the fifth hypothesis of measuring the business ethics levels of Taiwanese ITPs the Null and Alternative Hypotheses are defined as follows:
H0: In the ethical climate of independence, the business ethics level of Taiwanese ITP's is high.
H1: In the ethical climate of independence, the business ethics level of Taiwanese ITP's is low.
Results of Testing Hypothesis Five
It has been established in the fourth hypothesis that the greater the ethical climate of independence, the greater the level of ethical self-direction and ownership of ethical outcomes. This also holds true when the ethical climate of instrumental low. The adherence to self-defined ethical standards is high. When the specific variable of in this company, the employees are expected to do their job according to their personal belief of ethics is correlated against the variable of in this company, the employees can make decisions based on their personal judgment,…
