| What is the relationship between t and F if both are performed for a two-group test? (Points : 1) |
ANOVA will have the lower rate of type I error. t = F t will have less error variance. t2 = F |
| Question 2. 2. The number of sets of measures that a within-subjects F will accommodate is ___________. (Points : 1) |
one two two or more three or more |

Nominal Ordinal Interval Ratio |
| Question 8. 8. The test statistic in ANOVA is which ratio? (Points : 1) |
Error variance divided by variance within groups Between groups variance divided by error variance Total variability divided by error variance Error variance divided by between groups variance |
| Question 9. 9. What is the highest value eta-square can have? (Points : 1) |
There is no upper limit. 1.0 .5 .25 |
| Question 10. 10. If a one-way ANOVA and a within-subjects F were calculated for the same set of data, how would the SStot values compare? (Points : 1) |
SStot for the one-way ANOVA would be larger. The SStot values would be the same for each test. The SStot for the one-way ANOVA would be smaller. The SStot for the within-subjects F would contain a larger portion of error. |
