QUESTION 5

1. You estimate a simple regression predicting first year grade point average GPA for 200 first year college students from the number of classes they have missed. GPA is a continuous variable that ranges from 0.00 to 4.00. The unstandardized regression coefficient is -0.11. What is the correct interpretation of the regression coefficient?

1		For each additional class that a student misses, their GPA decreases by 0.11, on average.
2		Students who miss classes have GPAs that are 0.11 points lower, on average, than students who do not miss classes.
3		A one point increase in GPA is associated with missing 11 fewer classes.
4		Students with high GPAs miss 0.11 fewer classes than students with low GPAs.
