ANOVA is used for continues variable in one to one model,
however, in this case, there are X2 (Gender), X3 Student ,X4 Year ,X5 Semester ,X6 Size ,five independent variable. Only one dependent varialbe(Y Score), therefore, we should use multivariate or logistic Regression Model. If the dependent variable (Y Score ) is continues variable, for example 10,25,85,the ultivariate is suitable. On the other hand, category variable, for example, excellent=1, good=2, bad=3, should be analyzed by logistic Regression Model.
