When intelligence tests, such as the Stanford-Binet or Wechsler Intelligence Scale for Children (WISC), are used to predict academic performance, the results indicate that the tests generally show a correlation of:
A)+0.50 with school grades, and therefore the tests lack predictive validity
B)-0.50 with school grades, indicating the tests have good predictive validity
C)-0.50 with school grades, and therefore the tests lack predictive validity
D)+0.50 with school grades, indicating the tests have good predictive validity
