"Lоsing Weight Mаy Require Sоme Seriоus Fun" (New York Times, June 4, 2014). A recent study took 56 heаlthy аdult women where the majority were overweight. Each were told that they would walk for a half-hour with lunch to follow. Before they began, the women were randomly divided into two groups, each having 28 women. One group was told their walk was meant to be for exercise while the other group was told their walk would be purely for pleasure. After the walk, each woman sat and ate lunch. The exercise group consumed significantly more calories than the pleasure group, on the average. Identify the different aspects of this study.
