I am going over my research and I did an analysis of the mean of 6 variables on two quartiles drawn from a particular variable. I basically assigned to each observation its corresponding quartile and then I focused on the top and the bottom ones. I did a t-test to compare the mean of each of these 6 variables in each of the quartile. I am trying to see if there are some significant differences between a good performer (quartile calculation is based on gross margin) and a poor performer. My method is okay? and make s sense?

Thank you very much for your help!
