Exam 13: Correlation and Linear Regression

A Bonferroni test controls for:

The Bonferroni test controls for testwise alpha.

Using a within-subjects ANOVA design,

The test statistic for a one-way within-subjects ANOVA is mean square between groups divided by mean square error.

A researcher conducts two studies.In Study 1,she recorded the amount consumed (in calories)among 8 participants observed at three meal times (breakfast,lunch,and dinner).In Study 2,she conducted the same study,except that n = 12 participants observed at each of three meal times.Which study is associated with a larger value for degrees of freedom between-groups for a one-way within-subjects ANOVA?

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?

The term "within-subjects" refers to

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?

A researcher computes a one-way within-subjects ANOVA for a study in which participants are observed across five groups.If the degrees of freedom error is 56,then how many participants were observed in this study?

A researcher measures anxiety levels among participants in the presence and absence of a fearful stimulus.If the same participants are observed in each group,then what type of statistical design is appropriate for this study?

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?

For the one-way within-subjects ANOVA,the more ________ participant responding between groups,the less powerful the test will be at detecting an effect.

To summarize a one-way within-subjects ANOVA,we report each of the following except,

Because a one-way within-subjects ANOVA has two sources of error,it is associated with more error variability than a one-way between-subjects ANOVA.

With a small number of comparisons,the Bonferroni test is an appropriate post hoc test following a significant one-way within-subjects ANOVA.

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

To report the results of a post hoc test,identify which post hoc test was computed and the p value for significant results.

If 12 participants are observe din each of 4 groups,then the degrees of freedom between-persons is equal to 11.

Partial estimates of effect size make the denominator ________ because the between-persons variability is removed.

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