1. How can one investigate the question, "Is the psychological whole equal to the sum of its parts?"

a. Test for interaction in a factorial design.
b. By introspection.
c. By means of the Insert Function in Excel.
d. By means of Conditional formatting.
e. One cannot investigate this question, as shown by the Gestalt psychologists.

2. In the case of impression formation, can judgments of liking be represented as the sum or a simple weighted average of the likeableness of the person's traits?

a. Yes. The data showed that the additive model represents judgments of liking quite well.
b. No. The results show that people like a person as much as that person's best trait or quality.
c. No. The data show that people give extra weight to a person's worst trait or quality.
d. Yes. The data show that judgments of liking are parallel when plotted against the psychological scale values of the adjectives.
e. It is not possible to answer this question, because no experiment can answer it.

3. How does one test for an interaction in a factorial experiment?

a. Conduct an ANOVA and test the significance of the interaction by an F-test.
b. Plot the data as a function of the column levels, with a separate curve for each row. If the curves are parallel, there is no interaction; however, if the curves are not parallel, then there is an interaction.
c. Compute the difference between each pair of rows in each column. These differences should be equal for all columns if there is no interaction.
d. Find for each person, the difference between the first and last column in the first row; find the same difference in the last row. If there is no interaction, an equal number of subjects should have the first difference greater than the second, or the second greater than the first. If there is a systematic interaction, then more people will show one type of inequality than show the other.
e. All of the above test the interaction.

4. When checking data for "outliers" (or data that do not conform to the instructions), what technique(s) in Excel would be of use?

a. Conditional formatting.
b. Copy and Paste Special.
c. Save as HTML.
d. Insert Worksheet.
e. Both b and d.

5. If one finds data that are "out of bounds" for the instructions, what should one do?

a. Give up and study something else.
b. Put those sets of data aside for separate analysis.
c. Analyze the data with and without the questionable data, to see if they make a difference?
d. Plan the data checking in advance, and keep a record of any changes made before the analysis.
e. All but a.
