Question description

 Question 1. 1. The one in one-way ANOVA refers to ____________. (Points : 1)
the number of groups involved in the analysis
the number of pairs of groups involved in the analysis
the number of dependent variables in the ANOVA
the number of independent variables in the ANOVA

 Question 2. 2. The within-subjects F is the non-independent groups equivalent of the one-way ANOVA. (Points : 1)
True
False

 Question 3. 3. Why is matching uncommon when using the within-subjects F? (Points : 1)
With several measures matching is usually unnecessary.
Multiple before/after t-tests will provide the same data.
Matching won’t control the error variance in more than two subjects.
It’s difficult to find enough subjects that have the same characteristics.

 Question 4. 4. In an analysis of significant differences, any variance in scores not related to the independent variable is represented where? (Points : 1)
In any ancillary analysis that may be conducted
Error variance
In the differences between groups
As a portion of the treatment effect

 Question 5. 5. Which of the following is a primary source of error variance? (Points : 1)
Differences in the level of the treatment applied
Differences within the groups involved
The independence of the groups involved in the analysis
Differences in sample size

 Question 6. 6. Which of the following is a confounding variable? (Points : 1)
A variable that causes variance but is uncontrolled.
A variable that is mathematically controlled in an analysis.
A variable that is controlled but not measured.
A variable that correlates with other analyses.

 Question 7. 7. The point of a post-hoc test in ANOVA is __________. (Points : 1)
To determine statistical significance
To determine effect size
To determine error variance
To determine which pairs are significantly different

 Question 8. 8. How is the error term in the within-subjects F determined? (Points : 1)
All variance minus the variance related to measure-to-measure differences
The measure-to-measure differences minus the residual variability
The residual variability minus the treatment effect
All variance minus the treatment effect minus the subject-to-subject differences

 Question 9. 9. The term homogeneity of variance refers to which of the following conditions? (Points : 1)
All groups have similar amounts of data variability.
The same mean value occurs in each group.
All groups are drawn from the same population.
All groups have the same sample size.

 Question 10. 10. The treatment effect is a component of which of the following in the within-subjects F? (Points : 1)
The measure-to-measure differences
The subject-to-subject differences
The measure times subjects differences
The residual differences
