C.There was a single, continuous independent variable.

D.There were multiple, continuous independent variables.

E.There was a single, categorical dependent variable.

F.There were multiple, categorical dependent variables.

G.There was a single, continuous dependent variable.

H.There were multiple, continuous dependent variables.

Question 27

A.1

B.2

C.3

D.4

Question 28

28. Based on the statistic provided ( F(2, 15)=24.667, p<.05), how many subjects were in each group?

D.15

Question 29

29. If ANOVA is analysis of "variance", how are the variances analyzed in order to test the equality of means across groups?

A.The total variance of the data is partitioned within groups and between groups. Then, the ratio of the variability within group to the variability between groups is calculated.

B.The total variance of the data is partitionedbetweengroups and within groups. Then, the ratio of the variability between group to the variability within groups is calculated.

C.The total variance of the data is partitioned within groups and between groups. Then, the ratio of the means within group to the means between groups is calculated.

D.The total variance of the data is partitionedbetweengroups and within groups. Then, the ratio of the means between group to the means within groups is calculated.

Question 30

Which of the following is true about the Completely Randomized Design?Select allthat are true.

A.The design consists of multiple groups having independent subjects within each group.

B.The design consists of multiple observations taken from the same group of subjects

C.The data gathered from a CR design is analyzed with an ANOVA.

D.The data gathered from a CR design may be analyzed with many different types of analyses, including ANOVA, regression, and multivariate analysis.
