Use the following to answer the question(s) below.
A large pharmaceutical company selected a random sample of new hires and obtained their job performance ratings based on their first six months with the company. These data were used to build a multiple regression model to predict the job performance of new hires based on age, GPA and gender (female = 1 and male = 0). The results of the analysis are shown below.
-Which of the following is the correct interpretation for the regression coefficient of Gender?
A) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 points higher than for males of the same age and GPA.
B) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 points lower than for males of the same age and GPA.
C) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 times higher than for males.
D) The regression coefficient indicates that the job performance score for a female will, on average, be 9.06 times lower than for males.
E) The regression coefficient indicates that the job performance score for a female will, on average, be 2.314 times lower than for males.

Quizplus · Accepted Answer

The regression coefficient for Gender, when positive, indicates the average difference in the dependent variable (job performance score) between females and males, holding other variables constant. In this case, it suggests females score, on average, 9.06 points higher than males when age and GPA are the same.
