Question 1071320: The extent to which a person’s attitude can be changed depends in part on how big a change you are trying to produce. In a classic study on persuasion, Aronson, Turner, and Carlsmith (1963) obtained three groups of subjects. One group listened to a persuasive message that differed only slightly from the subjects’ original attitudes. For the second group, there
was a moderate discrepancy between the message and the original attitudes. For the third group, there was a large discrepancy between the message and the original attitudes. For each subject, the amount of attitude change was measured. Hypothetical data, similar to the experimental results, are as follows:
Size of Discrepancy
Small
1
0
0
2
3
0
Moderate
3
4
6
3
5
3
Large
0
2
0
4
0
0
Do the data provide evidence for significant differences between the three kinds of persuasion? Follow the Handout for conducting a One-Way Randomized ANOVA, α = .01

------------
Ho:: The means are equal
Ha:: At least one of the means is different
-----
Enter the data in a TI-84+ calculator in Lists L1,L2,L3
Select the ANOVA program (found under the STAT Key; Tests)
Results::
F = 9
p = 0.002703
Factor:
df = 2 ; SS = 36 ; MS = 18
---
Conclusion::
Since the p-value is less than 1%, reject Ho.
Conclusion:
At least one of the means is different.
