Assignment 4: Differences between three or more groups Work the following two problems using SPSS as appropriate. Be sure to attach (1) your responses to all of the questions, (2) your data for each problem, and (3) your relevant output. 1. A researcher wants to know whether there were significant differences in anger levels between Wrestlers, Football players, and Golfers at the college level. Anger is measured via a survey where the total score is calculated and can range between 1 and 40 with a higher score meaning more anger. Below is the data set to use to run the analyses. Wrestlers Football Golfers Players 13 20 26 23 21 33 23 22 28 4 31 30 12 24 21 10 20 37 21 39 21 19 16 31 12 19 32 18 21 32 a. State the hypothesis for the test you are conducting? b. Set the alpha = .05; Enter Data and Compute appropriate Test Statistic (ANOVA and pairwise comparisons) c. Make a decision about the null hypothesis. d. Calculate the effect size for the pairwise comparisons that are significant. Comment on the effect size. e. Type a summary reporting the results as you would for a journal article. Be sure to give the value of the test statistic and the exact significance level from the SPSS printout. f. Are there differences in anger levels for the various athletes? Justify your answer. 2. The researcher wants to know if there are differences in weight for males after participating in a structured physical activity and nutrition program short-term and long- term. They get weight assessments at baseline (prior to intervention), at 6-months after the intervention, and at 12 months after the intervention. Using the data from the table below carry out the relevant ANOVA and get SPSS to present appropriate statistics, including confidence intervals and pairwise comparisons.

State the hypothesis for the test you are conducting? b. Set the alpha = .05; Enter Data and Compute appropriate Test Statistic (ANOVA and pairwise comparisons) c. Make a decision about the null hypothesis. d. Report the overall measure of effect (partial eta²) and what it means. e. Type a summary reporting the results as you would for a journal article. Be sure to give the value of the test statistic and the exact significance level from the SPSS printout f. Did the weight loss intervention work? Why or why not?
