  1. James, thanks for all of your great videos. They are very helpful. I have a question about the way you test kurtosis in this video. You use the kurtosis stat, highlighting those with an absolute value greater than 2. Do you use the SPSS stat directly, or do you divide that stat by the kurtosis standard error? I thought you had to divide it by the SE.

  2. I’m not sure. Most of what I do is just what makes sense, not necessarily based directly on a journal article. I’ve never read an article that talked about unengaged responses (although I have one right now that is in second round of review).

  4. I just wanted to add, regarding the issue of unengaged responses: I have a lot of people with STDEV around 0, or less then .5. But this may well be because of the likelihood to hit the ceiling of scoring. Not sure how best to deal with this, because I don’t want to remove so many people (around 15%)…
