Hi everyone,
I am examining pearson's r correlation of two variables for a particular group, N=27. Because this group was selected from a much larger sample based on some criteria, the correlation size for the two variables for this particular group was greatly attenuated. My question is: is it possible at all to correct for range restriction using spss?
Thanks so much in advance for your help, and in the meantime, I will continue to look into this as well.
