I'm doing a study to characterize the students that choose a school. I want to find why they choose this school, why they choose each course of the school. they are going to fill some questionaires and I want to know which is the best DM Technique to analyze the results: Clustering, Association Rules??? (or just only statistics with SPSS - I rather use DM)
In my opinion, if you don't know the groups into which your data will be garthered, I'd choose Clustering. If you know, I'd choose some classification technique (ID4.5 used to be pretty popular). But you want to try to find a behavior, in which you can recognize a pattern to apply to new data, assossiation rules would do the job.
