Exam 13: Analysis of Variance: One-Way Within-Subjects Repeated Measures Design

A researcher has 18 participants rate the morality of a person described in a vignette as being registered as a Democrat,Republican,or Independent.If = 3.41 for a one-way within-subjects ANOVA,then what was the decision at a .05 level of significance?

A researcher recorded the shooting percentage of 28 professional basketball players in each of four quarters in a game.What are the degrees of freedom error for a one-way within-subjects ANOVA?

A Bonferroni test controls for:

Computing a one-way within-subjects ANOVA is appropriate when

Eta-squared is a more conservative measure of proportion of variance than partial eta-squared.

The formula for partial eta-squared and partial omega-squared removes the sum of squares within-groups from the total sum of squares.

The source of variation that is associated with differences between groups in a study is called

If the experimentwise alpha for three tests is .05,then what is the value for testwise alpha?

A researcher observes the same participants in each of five different settings.Which source of variation is the variability attributed to observing the same participants in all five settings?

Between-groups and between-persons variation are sources of error in the one-way within-subjects ANOVA.

A sex therapist has adult female clients rate their level of interest in each of six relationship situations.To analyze differences in the ratings,what type of statistical design is appropriate for this study?

The mean square for each source of variation is a measure of the mean distance that scores deviate from their mean.

A researcher measures the time it takes eight participants to complete three successive tasks.What are the degrees of freedom between-persons for a one-way within-subjects ANOVA?

The Bonferroni test controls for testwise alpha.

Which source of variation is computed using a one-way within-subjects ANOVA,but not a one-way between-subjects ANOVA?

The sum of squares within-groups and sum of squares between-persons are both sources of error.

For the one-way within-subjects ANOVA,the partial estimates of effect size remove,or "partial out," which source of variation?

A researcher computes a one-way within-subjects ANOVA in which k = 4 and n = 20.What are the degrees of freedom error for this test?

Which of the following is an assumption for the one-way within-subjects ANOVA,but not for the one-way between-subjects ANOVA?

A researcher measures the amount of high fat foods (in grams)consumed by 8 rat subjects 1 day,3 days,and 5 days following the introduction of a high fat diet.If = 30 and = 70 for a one-way within-subjects ANOVA,then what is the decision at a .05 level of significance?
