project descriptionWEEK 8 Application
Application: SPSS ExercisesComplete the following exercises in your course text Using SPSS for Windows and Macintosh: Analyzing and Understanding Data, by Green and Salkind. Be sure to save your
output and export it to your Word document, in which you also must answer the analysis questions and present your results section as indicated:Exercises 14 on p. 327, Chi-square test (Note: Use Lesson 40 Exercise File 1.sav)Exercises 14 on p. 343, Nonparametric proceduresExercises 15 on p. 354, Nonparametric procedures
Exercise 1-4 PG 328The data for Exercises 1-4 are in the data file s named Lesson 40 Data File 1 on the web at http://www.pearsonhighered.com/greensalkindSPSS. The data are based on the
following research study.
Kristen is interested in evaluating whether the method of cooking potato chips affects the taste of the chips. She has 48 individuals volunteer to participate in her
potato chip study. Each participant tastes chips cooked using three different methods: fried in animal fat(chip =1), fried in canola oil(chip=2), and baked (chip=3).
Individuals are instructed to indicate which type of potato chips they prefer: chip type1, chip type 2 or chip type 3. Kristen hypothesizes that individuals will
prefer potato chips that are fried in canola oil over those that are fried in animal fat or baked.1.Weight the data file by the number of cases to conduct the analysis.2.Conduct a one-sample chi square test to evaluate whether cooking methods affects taste. From the output, identify the following:a. Observed frequency for potato chips fried in canola oilb. p valuec. x2 value3. What are the expected frequencies for the three categories of potato chips?4. Write a results section based on the analyses.
Page 343The data for Exercises 1-4 are in the data file s named Lesson 42 Data File 1 on the web at http://www.pearsonhighered.com/greensalkindSPSS. The data are based on the
following research study.
Billie wishes to test the hypothesis that overweight individuals tend to eat faster than normal weight individuals. To test the hypotheses, she has two assistants sit
in Mc Donalds restaurant and identify individuals who order at lunch time the Big Mac special (Big Mac, large fries, and large coke). The Big Mackers as the assistants
affectionately called them, were classified by the assistants as overweight, normal weight or neither overweight or normal weight. The assitants identified 10
overweight BigMackers and 30 normal weight Big Mackers.(individuals who were neither overweight nor normal weight were disregarded.) The assistants record the amount
of time it took for the individuals in the two groups to complete their Big Mac special meals. One variable is weight with two levels, overweight(=1) and normal
weight(+2). The second variable is time in seconds.
1.Compute a MANN -Whitney U test on these data. From the output, identify the following;a. p valueb. z value corrected for tiesc.Mean rank for normal weight individuals2.Conduct an independent -samples test t test. Compare the p value for the Mann Whitney U test with the p value for the independent samples t test.3.Write a results section based on your analyses. What should you conclude?4. If you did not include a graph in your results section, create a graph that shows the distribution of the two groups.
Page 354 Exercises 1-5The data for Exercises 1-5 are in the data file s named Lesson 43 Data File 1 Exercise 1 on the web at http://www.pearsonhighered.com/greensalkindSPSS. The data are
based on the following research problem.
Marvin is interested in whether blonds, brunets, and redheads differ in their extroversion. He randomly samples 18 men from his local college campus: 6 blonds, 6
brunets, and 6 redheads. He then administers a measure of social extroversion to each individual.1.Conduct a Kruskal-Wallis test to investigate the relationship between hair color and social extroversion. Should you conduct follow up test?2.Compute an effect size for the overall effect of hair color on extroversion?3.Create a boxplot to display the differences among three groups distributions.4.Conduct a one-way NOVA on these data. How do the results for the ANOVA compare to the results of the Kruskal-Wallis test?5.Write a results section based on your analyses.
.Here are the comments from Instructor from Previous EXERCISES THAT WERE COMPLETED:
Note: Students must use a minimum of 85% peer reviewed sources from the total sources. Students must use a minimum of 85% of sources from the total sources that were
published within 5-years from the date the anticipated completion date (date that the CAO approves the final study). Other than data collected from the study site,
students cannot use magazines, trade publications, summary textbooks, websites, and blogs as references. For additional information, in APA manual, 6th edition, please
