Question
1.The treatment effect is a component of which of the following in the within-subjects F?
a)The measure-to-measure differences
b)The subject-to-subject differences
c)The measure times subjects differences
d)The residual differences
2.How are the subject-to-subject differences treated in the within-subjects F? (Points : 1)
a)They are added to the differences between measures.
b)They are calculated so that they can be eliminated.
c)They are the residual sum of squares that becomes the error term.
d)They are ignored in the analysis.
3.Dependent groups designs have what strength from the standpoint of analysis? (Points : 1)
a)They are more time efficient than independent groups designs.
b)They allow more variables to be analyzed than independent groups designs.
c)They eliminate initial between groups differences.
d)They allow for more liberal assumptions about data normality.
4. The point of the eta-squared test in ANOVA is to indicate _________. )
a)statistical significance
b)effect size
c)error variance
d)the location of significant differences
5. Post-hoc tests identify the location of significant differences in an ANOVA.
a)True
b)False
6. Which statistic is the best expression of error variance in an ANOVA?
a)MG
b)SSbet
c)SSwith
d)SStot
7. The number of sets of measures that a within-subjects F will accommodate is ___________.
a)one
b)two
c)two or more
d)three or more
8. In a two-group test, if a t is significant, the F will always be as well.
a)True
b)False
9. When the dependent groups tests use matched pairs, what is it that is matched?
a)Subjects are matched on the degree of error variance each one manifests.
b)Subjects are matched so that each pair receives the same treatment.
c)Subjects are matched on variables other than the IV that affect the DV.
d)Subjects are matched so that there are no differences in the level of the DV.
10. The within-subjects F is the non-independent groups equivalent of the one-way ANOVA.
a)True
b)False
1.The treatment effect is a component of which of the following in the within-subjects F?
Explanation / Answer
3:
In the dependent group design subjects are same in both conditions so difference of subjects eliminated. So any effect that appears due to difference in subjects under two conditions eliminated. Hence, option c)They eliminate initial between groups differences. is correct.
4:
Eta sqaure is used to measure the effect size in ANOVA analysis. Hence, option
b)effect size
is correct.
5:
If ANOVA gives that there is a significant difference between the population means under considersation then post-hoc test will be used. Post hoc test gives which pair (or pairs) of means are significantly different from each other. hence, its is true.
