Are any such transformations likely to have any effect on the normality (or the lack thereof) of the score data?
I’d read about the Box-Cox family of transformations: essentially proceeding through powers and their inverses, in the quest to improve normality. I decided to try it, using the Jarque-Bera statistic as a measure of the normality of the data.
