1. Identify the design (e.g., 2 X 2 factorial).

2. Identify the total number of conditions.

3. Identify the manipulated variable(s).

4.         Is this a repeated measures design? If so, identify the repeated variable(s).

5. Identify the dependent variable(s).

Design 1:

     College sophomores were given a short course in speed reading. Three groups had courses lasting for 5, 15, or 25 sessions. At the conclusion of the course, participants were asked to read a paragraph, followed by a test of comprehension. Before taking the test, participants in each group were offered a monetary incentive-no money, $1, or $10 for a certain level of performance. The researcher collected the reading time and number of correct items on the comprehension test for each participant.

Design 2:

     A researcher interested in weight control wondered whether normal and overweight individuals differ in their reaction 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. One manipulation was the proximity of the peanut dish (close or far from the participant); the second manipulation was whether the peanuts were shelled or unshelled. After filling out the questionnaire, the peanut dish was weighed to determine the amount of peanuts consumed.

Design 3:

     A researcher studied the influence of intensity of room illumination (low, medium, and high) on reading speed among fifth graders. Also, children were classified as "good" or "poor" readers from achievement test scores. Each group of children read 750-word passages under all three levels of illumination (three reading trials). The order of trials for each child was randomly determined.
