Hi, can you help? I am really struggling to find the answer to the following question.
I have conducted a standard multiple regression using SPSS. The dependent variable is CE, and the independent variables are Ibelieve and Tbelieve. Because the independent variables are highly correlated I have examined the squared semi-partial correlations. I understand that the Ibelieve squared semi partial correlation accounts for a significant proportion of the variance in CE t= 2.689, whereas the tbelieve does not t = .556. However, I want to see if the squared semi-partial correlations are significantly different TO EACH OTHER (Ibelieve .168, Tbelieve .035 N= 220). How do I do this? I assume that I will need to do this "by hand" with an equation? Also, do I have to take into account that the squared semi-partial correlations are correlated in terms of the dependent variable?
