Question 1. With fewer degrees of freedom and larger critical values to exceed, how can the dependent samples t be more powerful than the independent t?

      [removed] The larger critical value makes it easier to find statistical significance.
      [removed] The dependent groups tests tend to have larger treatment effects.
      [removed] The dependent groups tests can be repeated without affecting type I error.
      [removed] The larger critical value is offset by lower amounts of error variance.
 

 

 

Question 2. The within-subjects F is the non-independent groups equivalent of the one-way ANOVA.

      [removed] True 
      [removed] False 

 

Question 3. The post-hoc test for a within-subjects F test _____________.

      [removed] provides a measure of practical importance
      [removed] indicates the ratio of treatment effect to error variability
      [removed] indicates which set of scores are significantly different
      [removed] provides a test of the probability of committing a decision error

 

Question 4. Why is matching uncommon when using the within-subjects F?

      [removed] With several measures matching is usually unnecessary.
      [removed] Multiple before/after t-tests will provide the same data.
      [removed] Matching won’t control the error variance in more than two subjects.
      [removed] It’s difficult to find enough subjects that have the same characteristics.

 

Question 5. The term homogeneity of variance refers to which of the following conditions?

      [removed] All groups have similar amounts of data variability.
      [removed] The same mean value occurs in each group.
      [removed] All groups are drawn from the same population.
      [removed] All groups have the same sample size.

 

Question 6The point of the eta-squared test in ANOVA is to indicate _________.

      [removed] statistical significance
      [removed] effect size
      [removed] error variance
      [removed] the location of significant differences

 

Question 7. The number of sets of measures that a within-subjects F will accommodate is ___________.

      [removed] one
      [removed] two
      [removed] two or more
      [removed] three or more

 

Question 8. If there were four groups, how many possible pair-wise comparisons are there?  

      [removed] 3
      [removed] 4
      [removed] 5
      [removed] 6

 

Question 9. What is the statistical focus of a one-way analysis of variance?

      [removed] Means
      [removed] Variances
      [removed] Correlations
      [removed] People

 

Question 10. Using the same people repeatedly in a study has all but one of the following effects: (

      [removed] It increases the time needed for the study.
      [removed] It decreases the sample size needed for the study.
      [removed] It eliminates the error variance from the study.
      [removed] It makes smaller effects statistically significant.
