 SPSS data sets:

therapy.sav (question 1)

cardat.sav (question 2)

gradedat.sav (question 3)

1) Mean Comparison: T-test and One-Way ANOVA

1a) Using the data set therapy.sav, conduct two different t-tests: (a) comparing the depression scores of therapy A with therapy B and (b) comparing therapy A with Therapy C. On the output file, circle the group means, the t, as well as the significance level for each test

1b) Using the same data set, conduct a one-way ANOVA testing the depression scores for all three therapy groups with a Tukey HSD post hoc test. On the output file, circle the F and the significance level, as well as the significance level for each of the post-hoc tests. 

 2) Chi-square

Using the data set cardat.sav, conduct a chi-square analysis testing the association between car size and fatality. On the output file, circle the chi-square and the significance level.

3) Pearson r

Using the data set gradedat.sav, conduct a Pearson r analysis testing the association between absences and test scores. On the output file, circle the r and the significance level.
