A researcher runs a multiple linear regression predicting students’ exam score (0–100) from hours studied, GPA, and sleep hours. In the SPSS Coefficients table, the predictor “hours studied” has B = 2.40, SE = 0.80, t = 3.00, p = .003. Which interpretation is correct?
A
For each additional hour studied, exam score increases by about 2.40 points on average, holding GPA and sleep constant.
B
If hours studied increases by 1 SD, exam score increases by 2.40 points, holding other variables constant.
C
Hours studied explains 2.40% of the variance in exam scores after controlling for GPA and sleep.
D
A one-hour increase in studying causes exam scores to increase by 2.40 points for every student.
