Question
Please only select one answer per question
1. The one-way ANOVA is a little different from other tests because it uses the ratio of different types to test a hypothesis. The _____ variance should be roughly equal for the groups because the ANOVA assumes homogeneity of variance.
A. between-group
B. within-group
C. cohort-group
D. control-group
E. blind-group
2. To test for homogeneity of variance between the groups in a two-way ANOVA, the _____ test is used.
A. Levene's
B. Bonferroni
C. Box's M
D. Duncan
E. None of the above
3. When analyzing the results of the N-way ANOVA, one can say that a statistically significant difference between the means of the categories exists when the:
A. p-value of the computed f-statistic is less than a level chosen
B. computed f-statistic is more than the p-value
C. p-value of the computed f-statistic is more than a level
D. p-value and f-value are the same as a level
E. None of the above
4. When a null hypothesis is false after using the one-way ANOVA, it indicates there is some overlap, but the researcher still does not know exactly which variable is overlapping and by how much. This can lead to a type I error. To avoid this, _____ will decrease the likelihood of an error.
A. a post hoc test
B. a Kruskal-Wallis H-test
C. a chi-square test
D. the f test
E. None of the above
5. The N-way ANOVA is similar to the _____ as it can only tell us whether differences between the mean exist.
A. MANOVA
B. two-way ANOVA
C. one-way ANOVA
D. three-way ANOVA
E. None of the above
Explanation / Answer
1. between-group; Option A is correct.
2. Levene's; Option A is correct.
3. p-value of the computed f-statistic is less than a level chosen; Option A is correct.
4. a post hoc test; Option A is correct.
5. MANOVA; Option A is correct.
Note - Its very rare but all of the 5 questions have option A as the correct answer :D
