A school psychologist is interested in the efficiency of administration for a new intelligence test for children. In the past, the Wechsler Intelligence Scale for Children (WISC) was used. Thirty sixth grade children are given the new test to see whether the old intelligence test or the new intelligence test is easier to administer. Is this a non-directional or directional hypothesis? How do you know?
