Document Summary

2 independent variables, each on own and then together. Can have more than 2, but we will do the bare min of 2. E. g. whether gender as well as year of study impacts happiness. 2iv, do not worry about how many groups, as soon as 2 iv must run a factorial even if those variables themselves have 2 groups. Test to determine whether means on dependent variable are dif based on 2 or more independent categorical variables. Is this looking at diferent ppl: *key word is or, so yes we are looking at diferent ppl, can we conduct independent factorial anova, yes. Gn: dummy variables to idenify which cell we are trying to predict. There will always be one less than the number of cells. Bo the intercept, equals the mean of the cell that has dummy code of 0. Bn the diference btwn mean of each cell.
