I have a question regarding the elimination of participant data for two statistical analyses on the same sample.
Here is a bit of background information:
I collected data from one sample (n = 181 college students) and administered two questionnaires to them (one on spirituality and one on negative emotional states). I performed an exploratory factor analysis on the data from the spirituality questionnaire, and I want to compare the factors derived from the EFA to the negative emotional states using a hierarchical multiple linear regression.
My main question is the following:
When I analyzed the data with a hierarchical multiple linear regression, SPSS identified (via case diagnostics) participants whose data could be eliminated due to outlier scores. If I exclude these cases from the analysis, then do I have to remove them from the results of the EFA as well? (Both of these analyses would be featured in the results section of the same experiment.)
