I took "attitude towards mental illness" as a dependent variable and "gender" as the independent variable to find out the gender differences in attitude towards mental illness. The data was not following the normal distribution so I did the non-parametric test to find the difference. I found the result, I interpreted and communicated the paper to the journal. Now, the reviewer of the paper has asked to control the confounders like other socio-demographic variables which might influence the gender attitude like income, education and occupation etc. So, I request the experts to tell me how to control the confounders in SPSS. In case if you ask me to run ANCOVA and Multinomial Logistic Regression so I did that too. But since, I am rookie in statistics so unable to interpret the results. Please help me!
