  8. Examples • Emily is four years old. Her big sister Amy is three times as old as Emily. How old will Amy be when she is twice as old as Emily? • WOLF is to FLOW as 8526 is to: 2856 - 6258 - 5862 - 5682 - 6852

  9. Examples • Hanger is to closet as tree is to: Branch - Bushes - Forest - Ground - Nest • What would be the next number in this series? 15 ... 12 ... 13 ... 10 ... 11 ... 8 ... ?

  19. Reliability refers to the measurement consistency of a test (or other techniques). Example You take a personality test and are scored as “assertive”. Three weeks later you take the same test and are scored as “passive”. A drastic change is probably a result of an unreliable test. Reliability

  20. Testing Reliability Test-retest • Comparing subjects’ scores on two administrations of a test. Correlation Coefficient • A numerical index of the degree of relationship (-1, +1)
