I followed an earlier post on this forum to conduct test of mean differences for a quartile ranked variable.
proc glm data=comb;
model disc = H_quar;
means H_quar / cldiff T;
H_quar is the quartile ranked variable. I am interested in if disc variable differs significantly between quartile 4 and 1.
i attached sas results, My question is on line (3-0), i.e., quartile 4 and 1., is the results significant at conventional levels?
