2 H 0 = The ratings of the mother’s expressions have no effect on the baby’s movement (r=0) H 1 = The ratings of the mother’s expression have an effect on the baby’s movement. (r 0) The higher the mother’s score on the negative scale, the less forward movement by the baby. #1 Visual Cliff Example #1 Visual Cliff Example • Even though using a directional hypothesis, will still use a 2-tailed distribution • Conservative measure – chance could go in the other direction Step 2: Visual Cliff Example • DV#1: Ratings of mother’s negative expression on a scale of 0 - 6 06 3 Interval! Interval! #2 Visual Cliff Example • DV #2: Measurement of forward movement in centimeters (cm) out of a possible 1,000cm Ratio!
