The answer should have the following:

- State the interest of the question - Define the variables e.g. students stress scores (STRESS) were - Describe the groups (range of scores & number in each, M & SD if applicable) - Name the test used - Report the statistical result (2 decimal places, APA formatted- symbols in italics!). Frequencies are reported in whole numbers. - Concluding/summarizing statement- interpret the results in words. What does it mean

1. Determine whether students who would not take PSYC3015 if it were not a required course at time 2 (COURSE2: 1= No, 2 = Yes) differ significantly in their self-efficacy at time 2 (SETIME2) in comparison to those who would take PSYC3015 if it were not a required course. Include in your report the 95% confidence interval, power and the effect size.
