What are the most common questions about correlation?
Let’s proceed further and learn about the most commonly asked questions asked on correlation. If you are learning statistical concepts, you are bound to face these questions which mostly people try to avoid. For people like me, it should be a good refresher.

In the survey I had one ‘normal condition’ and one ‘physically not fit condition’. In SPSS that is: 1=Normal; 2=NotFit. The investment decision is: 1=Yes; 2=No. Is it possible to run a correlation analysis on this to see what the effect of the IV on the DV is?
Which is the best way to analyze repeated measures?
Analyzing non-independent data with techniques that assume independence is a widespread practice but one that often produces erroneous results ( Kenny and Judd, 1986; Molenaar, 2004; Aarts et al., 2014 ). One common solution is to average the repeated measures data for each participant prior to performing the correlation.
