In Study 2, Bryant and colleagues (2005) recruited a sample of 65 college students. Participants were randomly assigned to one of three conditions:

• Cognitive imagery reminiscing
• Memorabilia reminiscing, and
• Control (no reminiscing).

Participants were in each group were instructed to use these strategies over one week. After the week was over, they reported their happiness levels.

Results of the study indicated that there wasNOsignificant omnibus difference in happiness level,F(2, 60) = 2.39,p >0.05.

Question 12 of 393 Points

Justify your answer, above

• A.

ANOVA can be used when you have with three or more levels of an independent variable

• B.

You can use ANOVA with three levels, but at-test would be easier and give you the same results

• C.

ANOVA's primary strength is its ability to examine for differences in two groups

• D.

Regression analysis would be preferable because the independent variable is continuous

Question 13 of 393 Points

How would you interpret the results of this oneway ANOVA?

• A.

There is likely a difference in happiness in the "population"

• B.

Those who spend time reminiscing are significantly more likely to be happy than those who don't

• C.

There are mean differences but we do not know which conditions differ

• D.

There are no mean differences in happiness across the three conditions

• A.

Within groups variance

• B.

• D.

Total variance

Question 15 of 392 Points

Broadly speaking, what is the Fratio used in ANOVA?

• A.

A ratio of variances that tells if differences between groups are larger than differences within groups

• B.

A ratio of variances that tells you which individual group(s) is/are different from the other(s)

• C.

A ratio of sums of squares that tells us which specific group(s) is/are different from the other(s)

• D.

A ratio of sums of squares that tells if differences between groups are larger than differences within groups

Question 16 of 392 Points

Should post hoc tests be conducted after this analysis?

• A.

No - without a significant omnibusF, there is no need to conduct post hoc tests

• B.

Yes - without post hoc tests, Bryant and colleagues (2005) would not know which means differed

• C.

No - with only two groups, looking at the descriptive statistics will give all the relevant information

• D.

Yes - post hoc tests are always used when conducting a oneway ANOVA
