The state of California conducted an experiment with college students. Teachers and students were randomly assigned to be in a regular sized class or a small sized class. The dependent variable is the student’s score on a math test (MATHSCORE). Let SMALL = 1 if the student is in a small class and SMALL = 0 otherwise. The other variable of interest is the number of years of teacher experience, given by TCHEXPER. Let BOY = 1 if the stu-...
