For this question, use the global coglab data for this lab presented here:

Actual recognition memory (%correct) Predicted Recog Memory (% correct)

Studied once studied twice studied once studied twice

Small font 80.4 91.2 41.7 45.5

Large font 83.1 93.2 54.9 58.5

a. For actual memory, how much did studying 2 times vs 1 time improve memory after averaging over small vs large font size? ___ percentage points

Use this formula, using the actual memory numbers on the left:

([studied 2x small font +studied 2x large font] / 2)

([studied 1x small font +studied 1x large font] / 2)
