I was interested in whether students’ knowledge of different aspects of psychology improved throughout their degree (psychology.sav). I took a sample of firstyears, 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.
