If we are using one numerical variable and one or two Categorical features were more than 2 categories then we r using the Annova test. 
And if we are using one numerical variable and one categorical variable where only two category then we have to use T-Test. 
And if are using two categorical feature and reject null hypothesis and we choose alternate hypothesis the we have to use CHi- square
