Chapter 12
Question 2. Brief answer
Question 18. (ignore instructions in the book and follow the steps I describe above. Do the problem both ways, i.e., showing all the work [EXCEL or writing it out] AND using one of the software options [SPSS or Jamovi — cut and paste results]). Assume that you predict that the “text” group will have higher ratings of competence than the other two groups (i.e., you make specific predictions). Produce a chart that helps you interpret the findings and include error bars (95% confidence intervals) for groups. Be specific with respect to any group mean differences you find. Report effect size for overall F-test.
**note, effect size for ANOVA is eta-squared
Non-book questions (use the data sets provided on the blackboard to answer these questions).
1. Using the Politics data set, test whether mean levels of the personality factors openness to experience (opentot) and disagreeableness (disagreeable) differ across the political party groups (polparty: republicans, democrats, independents and not registered). Assume that this is an exploratory analysis, and you have no predictions about how the groups might differ, thus, you want greater protection against making a type 1 error. Produce charts that helps you interpret the findings and include error bars (95% confidence intervals) for groups. Be specific with respect to any group mean differences you find, i.e., tell me who is significantly higher/lower. Report effect size for overall F-test.
