## SPSS Correlations without Significance

SPSS CORRELATIONS generates tables containing correlations, the N for each correlation and its supposed significance. Unfortunately, there's no simple way to suppress the latter two pieces of information. This tutorial therefore proposes a simple tool for hiding the significance and/or N after the correlation tables have been produced. Read More
