Module Five Worksheet: Factorial Design
Scenario: A researcher interested in weight control wondered whether normal and overweight
individuals differ in their reactions to the availability of food. Thus, normal and overweight
participants were told to eat as many peanuts as they desired while working on a questionnaire.
Participants filled out the questionnaire once, were given an opportunity to ask additional
questions, and then were free to leave. One manipulation was the proximity of the peanut dish
(close to or far from the participant); the second manipulation was whether the peanuts were
shelled or unshelled. After each participant filled out the questionnaire, the peanut dish was
weighed to determine the amount of peanuts consumed.
