WebA possible issue with using the Pearson correlation for two dichotomous variables is that the correlation may be sensitive to the "levels" of the variables, i.e. the rates at which the variables are 1. Specifically, suppose that you think the two dichotomous variables (X,Y) are generated by underlying latent continuous variables (X*,Y*). Web• The population correlation coefficient has the symbol “ρρρ”. Chapter 5 # 10 Interpreting r • The sign of the correlation coefficient tells us the direction of the linear relationship If r is negative (<0) the correlation is negative. The line slopes down If r is positive (> 0) the correlation is positive. The line slopes up
