Task 3: I was interested in whether students’ knowledge of different aspects of psychology improved throughout their degree (Psychology.sav). I took a sample of first-years, second-years and thirdyears and gave them five tests (scored out of 15) representing different aspects of psychology: Exper

(experimental psychology such as cognitive and neuropsychology); Stats (statistics); Social (social psychology); Develop (developmental psychology); Person (personality). (1) Determine whether there are overall group differences along these five measures. (2) Interpret the scale-by-scale analyzes of group differences. (3) Select contrasts that test the hypothesis that second- and third-years will score higher than first-years on all scales. (4) Select post hoc tests and compare these results to the contrasts. (5) Carry out a discriminant function analysis including only those scales that revealed group differences for the contrasts. Interpret the results.
