I have 1 subject rating 40 participants on the big five personality traits and other variables. these 40 participants are in 2 conditions (20 each). I want to compare whether there is a difference between how the subject rates the two conditions. I know it sounds like paired samples, but doesn't paired samples compare the difference of 2 answers for the same participant? I have one subject giving 40 answers.
Also practically, how should I construct my data set? Paired samples cannot test the difference between conditions. I would have to make new variables for condition 2 and then compare these. In SPSS, however, won't it look as if participant 1 and participant 20 are the same person, since their columns would be next to each other on the data set.
Any tips on what analysis to use? I have to hand in the study in a few days, so fast advice would be appreciated!
