New Member
Ok so i have this question for uni. where i have to test the hypothesis that "Using a planned contrast approach, test the hypothesis that the following combined groups have equal means on the google_academic dependent variable: ‘primary’ combined with ‘high school’ versus ‘undergraduate’ combined with ‘post-graduate'" Where these are just the variables names.

Hopefully someone can tell me how to go about this...because i am totally confused :(
