The above is the STATA 's regression output when you regress totalscore (combined Math and Reading test scores) on small. Small = 1 if students were assigned to a small class size (13-17 students) and it is 0 if they were assigned to a larger class size (22-25 students). The minimum totalscore is 635, maximum is 1253, and the mean is 922.329 points, respectively. This is individual level student data. What is Var(y) = s2y in the above output?
