If there is a variation, then it can co-vary with another variable that also varies (change systematically and check for correlation): distribution: to look into the distribution out of interest. Here"s the distribution of marks for test #1: Soc 222: frequency distribution of marks for test #1. Yes, not everyone (or even close) to being in the same category. When looking at distribution within the category to state that there is variation in the grades (so not everyone is getting the same grades) New document on web site: spss frequency distributions. This opens a box called frequencies : on the left: list of variable labels, variable names (depart) vs variable labels (department) In the lists, the variable name is given in [ ] square brackets!
