Source of VariabilitySSdfMSFBetween Groups1025F=1.47Within Groups75223.41Total12524

Group of answer choices

The F ratio is significant

You would run post hoc tests on this ANOVA

The F ratio is not significant

Question 7

Group of answer choices

z-test

Independent-samples t-test

Related-samples t-test

One-way ANOVA

Question 8

ANOVAs are different from the t-test because

Group of answer choices

ANOVAs use standard deviation to compare group means.

ANOVAs use variance to determine differences in group means.

ANOVAs compare the sample means of 2 groups.

ANOVAs do not look at group differences

Question 9
