I am doing research in Psychology. The research question is "There is a relationship between sleep quality and academic performance". My two variables are sleep quality and academic performance. I know what test to perform here.
I also want to test how these two variables vary with gender, student status (being a student), and economic status. Which statistical test should be used to analyze this?
I just need to know the name of the test, not looking for any instructions on how to test it (i.e., whether it is Anova, Anacova, or anything else). I am sure anyone who had done similar research knows what test to use.
Thanks,
