So I have a group of students all divided by different categories in response to a poll. There is a total of 34 students. Depending on each answer, I assigned the student a 1, 2, 3, or 4 for that category. For example, favorite candy 1 = twix 2 = snickers 3 = gum 4 = none. Now that I've divided them up into 4 categories, how can I find if there is a statistical difference between the candy they prefer? Is this also called categorical data? Thanks!
