Question

Scenario:            Based upon the work of Elizabeth Loftus, a researcher was interested in testing the most effective way to implant false memories in people. First, she had all subjects watch a 60 minute movie. Then she randomly assigned these subjects to one of four conditions, each of which used different assessment techniques to influence subjects to think they saw something that didn't actually occur. Condition A utilized falsified photos, condition B utilized falsified video, condition C utilized misleading narrative, and condition D was a control group with no intervention at all. The data below shows how many false memories subjects in each condition 'remembered'.

Condition A: {x_A} = (4,8,6,6,5,9)

Condition B: {x_B} = (9,10,7,9,11,7)

Condition C: {x_C} = (2,1,2,2,4,3)

Condition D: {x_D} = (0,2,1,1,0,3)

1. Calculate the mean, df, and the sum of squares for each of the four conditions [2 marks]
