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 third years 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 analyses 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.
