Part A
Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Test Resources link.
1. For the following research questions, create one null hypothesis, one directional research hypothesis, and one nondirectional research hypothesis.
a. What are the effects of attention on out-of-seat classroom behavior?
Research Hypothesis: There will be a relationship between the effects of attention on out-of-seat classroom behavior versus in-seat-classroom behavior.
b. What is the relationship between the quality of a marriage and the quality of the spouses’ relationships with their siblings?
Null Hypothesis: There will be no relationship in the relationship between the quality of a marriage and the quality of the spouses’ relationship with their siblings.
c. What is the best way to treat an eating disorder?
One Directional Research Hypothesis:
2. Provide one research hypothesis and an equation for each of the following topics:
a. The amount of money spent on food among undergraduate students and undergraduate student-athletes
b. The average amount of time taken by white and brown rats to get out of a maze
c. The effects of Drug A and Drug B on a disease
d. The time to complete a task in Method 1 and Method 2
3. Why does the null hypothesis presume no relationship between variables?
4. Create a research hypothesis tested using a one-tailed test and a research hypothesis tested using a two-tailed test.
5. What does the critical value represent?
6. Given the following information, would your decision be to reject or fail to reject the null hypothesis? Setting the level of significance at .05 for decision making, provide an explanation for your conclusion.
a. The null hypothesis that there is no relationship between the type of music a person listens to and his crime rate (p < .05).
In Hypothesis Testing, we typically deem a research hypothesis to be significant, if the odds of two means actually being equal are no greater than 1 in 20 or .05 (5%) or less.
b. The null hypothesis that there is no relationship between the amount of coffee consumption and GPA (p = .62).
c. The null hypothesis that there is a negative relationship between the number of hours worked and level of job satisfaction (p = .51).
7. Why is it harder to find a significant outcome (all other things being equal) when the research hypothesis is being tested at the .01 rather than the .05 level of significance?
At the .01 level, there is less room for error because the test is more rigorous.
8. Why should we think in terms of “failing to reject” the null rather than just accepting it?
9. When is it appropriate to use the one-sample z test?
10. What similarity does a z test have ...

Last semester in Research Methods and Design One (and last week in Chapter 9, Smith and Davis), we talked about normal curves and why we need normality in order to run ANOVAs, t-Tests, and other “parametric” tests.
“Parametric tests” infer that the results obtained from a sample in the study easily applies to a population from which that sample was drawn. But such “normal” tests are based on a series of assumptions …
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
Four parametric test assumptions:
Assumption #1: Variances in each group are homogenous (that is, the two or more groups are similar in variability)
Assumption #2: The sample is large enough to adequately represent the population (e.g. it isn’t a biased sample)
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
Four parametric test assumptions:
Assumption #3: The statistical test uses interval or ratio scales of measurement (the I and R in NOIR)
Assumption #4: The characteristic under consideration is normally distributed (i.e. has a normal curve)
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
So what happens when/if a test violates these assumptions?
In some cases, t-Tests, ANOVAs, and other parametric tests are robust (e.g. strong enough) that the assumptions can be violated without too much hassle.
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
So what happens when/if a test violates these assumptions?
Non-parametric tests may be used when assumptions are violated
“Non-parametric” statistics are essentially distribution-free, meaning they don’t follow the same rules as the parametric tests

Introduction - Non-Parametric Stat.
Bacteria decode their genetic information through transcription and translation to produce proteins. During transcription, the bacterial DNA is used as a template to produce mRNA. The mRNA then directs protein synthesis during translation, where ribosomes in the bacterial cytoplasm read the mRNA to assemble amino acids in the correct order specified by the mRNA to produce proteins. This allows bacteria to regulate gene expression and carry out necessary functions and processes.

Problem 1)
Steven collected data from 20 college students on their emotional responses to classical music.
Students listened to two 30-second segments from “The Collection from the Best of Classical Music.”
After listening to a segment, the students rated it on a scale from 1 to 10, with 1 indicating that it “made them very sad” to 10 indicating that it “made them very happy.” Steve computes the total scores from each student and created a variable called “hapsad.”
Steve then conducts a one-sample t-test on the data, knowing that there is an established mean for the publication of others that have taken this test of 6.
The following is the scores:

Billie wishes to test the hypothesis that overweight individuals tend to eat faster than normal-weight individuals.
To test this hypothesis, she has two assistants sit in a McDonald’s restaurant and identify individuals who order the Big Mac special for lunch.
The Big Mackers as they become known are then classified by the assistants as overweight, normal weight, or neither overweight nor normal weight.
The assistants identify 10 overweight and 10 normal weight Big Mackers.
The assistants record the amount of time it takes them to eight the Big Mac special.

Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.
Using the same data set (Ch. 11 Data Set 2), test the research hypothesis at the .01 level of significance that there is a difference between boys and girls in the number of times they raise their hands in class. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? You used the same data for this problem as for Question 1, but you have a different hypothesis (one is directional and the other is nondirectional). How do the results differ and why?
Practice the following problems by hand just to see if you can get the numbers right. Using the following information, calculate the
t
test statistic.
Using the results you got from Question 3 and a level of significance at .05, what are the two-tailed critical values associated with each? Would the null hypothesis be rejected?
Using the data in the file named Ch. 11 Data Set 3, test the null hypothesis that urban and rural residents both have the same attitude toward gun control. Use IBM

A public health researcher tested the hypothesis that providing new car buyers with child safety seats will also act as an incentive for parents to take other measures to protect their children (such as driving more safely, child-proofing the home, and so on). Dr. L counted all the occurrences of safe behaviors in the cars and homes of the parents who accepted the seats versus those who did not. The findings: a significant difference at the .013 level. Another researcher did exactly the same study; everything was the same—same type of sample, same outcome measures, same car seats, and so on. Dr. R’s results were marginally significant (recall Ch. 9) at the .051 level. Which result do you trust more and why?
In the following examples, indicate whether you would perform a
t
test of independent means or dependent means.
Two groups were exposed to different treatment levels for ankle sprains. Which treatment was most effective?

Unit V Research Paper
Freedom of speech and freedom of the press are two important rights individuals have in the United States. Today, there are so many news outlets featured on the radio, television, cable, and the Internet that are competing for our attention to the degree that some news media emphasize very sensitive and controversial subjects as a means to simply attract an audience. Some individuals criticize this practice as being harmful to society. Yet, others claim it is appropriate to report this type of speech in such a fashion.
Research the topic,
Freedom of the Press
, and write a research paper that explains your views on freedom of the press and whether this trend toward reporting sensitive topics does or does not have a negative impact on some work environments.
Make sure that your paper has the following components: BBA 3361, Professionalism in the Workplace 3
Introduction
- State your thesis and the purpose of your research paper clearly. What is the chief reason you are writing the paper? State also how you plan to approach your topic. Is this a factual report, a book review, a comparison, or an analysis of a problem? Explain briefly the major points you plan to cover in your paper and why readers should be interested in your topic.
Body
- Present your arguments to support your thesis statement. This should be one to three paragraphs in length.
Conclusion
- Restate or reword your thesis. Summarize your arguments. Explain why you have come to this particular conclusion.
Your paper should be three to five pages in total length, using 12-point double-spaced Times Roman font using APA format.

c. What is the best way to treat an eating disorder?
One Directional Research Hypothesis:
2. Provide one research hypothesis and an equation for each of the following topics:
a. The amount of money spent on food among undergraduate students and undergraduate student-athletes
b. The average amount of time taken by white and brown rats to get out of a maze
c. The effects of Drug A and Drug B on a disease
d. The time to complete a task in Method 1 and Method 2
3. Why does the null hypothesis presume no relationship between variables?
4. Create a research hypothesis tested using a one-tailed test and a research hypothesis tested using a two-tailed test.
5. What does the critical value represent?
6. Given the following information, would your decision be to reject or fail to reject the null hypothesis? Setting the level of significance at .05 for decision making, provide an explanation for your conclusion.
a. The null hypothesis that there is no relationship between the type of music a person listens to and his crime rate (p < .05).
In Hypothesis Testing, we typically deem a research hypothesis to be significant, if the odds of two means actually being equal are no greater than 1 in 20 or .05 (5%) or less.
b. The null hypothesis that there is no relationship between the amount of coffee consumption and GPA (p = .62).
c. The null hypothesis that there is a negative relationship between the number of hours worked and level of job satisfaction (p = .51).
7. Why is it harder to find a significant outcome (all other things being equal) when the research hypothesis is being tested at the .01 rather than the .05 level of significance?
At the .01 level, there is less room for error because the test is more rigorous.
8. Why should we think in terms of “failing to reject” the null rather than just accepting it?

Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
Last semester in Research Methods and Design One (and last week in Chapter 9, Smith and Davis), we talked about normal curves and why we need normality in order to run ANOVAs, t-Tests, and other “parametric” tests.
“Parametric tests” infer that the results obtained from a sample in the study easily applies to a population from which that sample was drawn. But such “normal” tests are based on a series of assumptions …
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
Four parametric test assumptions:
Assumption #1: Variances in each group are homogenous (that is, the two or more groups are similar in variability)
Assumption #2: The sample is large enough to adequately represent the population (e.g. it isn’t a biased sample)
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
Four parametric test assumptions:
Assumption #3: The statistical test uses interval or ratio scales of measurement (the I and R in NOIR)
Assumption #4: The characteristic under consideration is normally distributed (i.e. has a normal curve)
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
So what happens when/if a test violates these assumptions?
In some cases, t-Tests, ANOVAs, and other parametric tests are robust (e.g. strong enough) that the assumptions can be violated without too much hassle.
Introduction - Non-Parametric StatisticsIntroduction To Non-Parametric Statistics
So what happens when/if a test violates these assumptions?
Non-parametric tests may be used when assumptions are violated
“Non-parametric” statistics are essentially distribution-free, meaning they don’t follow the same rules as the parametric tests
They don’t require homogeneity of variance and they can examine more than just interval and ratio data

Introduction - Non-Parametric Stat.
Bacteria decode their genetic information through transcription and translation to produce proteins. During transcription, the bacterial DNA is used as a template to produce mRNA. The mRNA then directs protein synthesis during translation, where ribosomes in the bacterial cytoplasm read the mRNA to assemble amino acids in the correct order specified by the mRNA to produce proteins. This allows bacteria to regulate gene expression and carry out necessary functions and processes.

Steven collected data from 20 college students on their emotional responses to classical music.
Students listened to two 30-second segments from “The Collection from the Best of Classical Music.”
After listening to a segment, the students rated it on a scale from 1 to 10, with 1 indicating that it “made them very sad” to 10 indicating that it “made them very happy.” Steve computes the total scores from each student and created a variable called “hapsad.”
Steve then conducts a one-sample t-test on the data, knowing that there is an established mean for the publication of others that have taken this test of 6.

A public health researcher tested the hypothesis that providing new car buyers with child safety seats will also act as an incentive for parents to take other measures to protect their children (such as driving more safely, child-proofing the home, and so on). Dr. L counted all the occurrences of safe behaviors in the cars and homes of the parents who accepted the seats versus those who did not. The findings: a significant difference at the .013 level. Another researcher did exactly the same study; everything was the same—same type of sample, same outcome measures, same car seats, and so on. Dr. R’s results were marginally significant (recall Ch. 9) at the .051 level. Which result do you trust more and why?
In the following examples, indicate whether you would perform a

Unit V Research Paper
Freedom of speech and freedom of the press are two important rights individuals have in the United States. Today, there are so many news outlets featured on the radio, television, cable, and the Internet that are competing for our attention to the degree that some news media emphasize very sensitive and controversial subjects as a means to simply attract an audience. Some individuals criticize this practice as being harmful to society. Yet, others claim it is appropriate to report this type of speech in such a fashion.
Research the topic,
Freedom of the Press
, and write a research paper that explains your views on freedom of the press and whether this trend toward reporting sensitive topics does or does not have a negative impact on some work environments.
Make sure that your paper has the following components: BBA 3361, Professionalism in the Workplace 3
