Answer the same six questions for the experiments described below:
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.
1. Identify the design (e.g., 2 X 2 factorial).
2. Identify the total number of conditions.
3. Identify the manipulated variable(s)/Independent variables.
4. Is this an IV X PV design? If so, identify the participant variable(s).
5. Is this a repeated measures design? If so, identify the repeated variable(s).
6. Identify the dependent variable(s).
Outcomes of Factorial Designs
19. Outcome 1:
B1 B2
A1 4 6
A2 3 8
1. Is there a main effect of IV A?
Overall means of A1 _____ A2 _____
2. Is there a main effect of IV B?
Overall means of A1 _____ A2 _____
3. Is there an A X B interaction?
4. Graph the results.
You can draw a graph and take the picture of the graph, and put the picture here or submit the picture in a separate file,
You certainly can use computer to graph the results
20. Outcome 2:
B1 B2
A1 30 30
A2 20 40
1. Is there a main effect of IV A?
Overall means of A1 _____ A2 _____
2. Is there a main effect of IV B?
Overall means of B1 _____ B2 _____
3. Is there an A X B interact
