We could answer your question for theoretical interest, but I think we can say with absolute confidence there is no way those small differences in estimated correlation will be statistically significant evidence of a difference in the real population, given your sample size. | |

My previously conclusion resulted from a gross tabulation error (i.e., only 84 of my 4000 cases apparently have post scores, which I was not previously aware of). Regardless of the practical meaningfulness of the differences, I would like to know how I could calculate for statistical differences, for this paper and for the future. | |
