Each year a nationally recognized publication conducts its "Survey of America's Best Graduate and Professional Schools." An academic advisor wants to predict the typical starting salary of a graduate at a top business school using GMAT score of the school as a predictor variable. A simple linear regression of SALARY versus GMAT using 25 data points shown below.
b0 = -92040  b1 = 228  s = 3213  R2 = 0.66  r = 0.81  df = 23  t = 6.67
Give a practical interpretation of R2 = 0.66.
◦ 66% of the differences in SALARY are caused by differences in GMAT scores.
◦ 66% of the sample variation in SALARY can be explained by using GMAT in a straight-line model.
◦ We estimate SALARY to increase $.66 for every 1-point increase in GMAT.
◦ We can predict SALARY correctly 66% of the time using GMAT in a straight-line model.
