It's funny you mentioned that, that's part of the reason I put 30 questions in the survey over multiple pages. I'm really only trying to correlate a very small percentage of the questions, so I had to try to trick the respondent. Some of the ancillary questions are there to help find outliers and/or identify people who are trying to "cheat their answers" so their responses can be disqualified.

Unfortunately this class (essentially spreadsheet modeling) is coming a semester before my market research classes which get in to exactly what you were talking about.

I'll message you privately about one of the points you made because you just pinpointed something we were cracking up laughing over.
