sssweitzer Posted January 9, 2014 Report Share Posted January 9, 2014 My topic of my IA is the coca-cola challenge and I am trying to prove that your age, gender, and origin influence the preference in brand cola between Coke and Pepsi. I was planning on doing the chi-squared test, but I don't know what other sophisticated process I should do. I have many variable to test. Please help!!
