Exam 13: Repeated-Measures and Two-Factor Anova

A repeated-measures analysis of variance for a study comparing three treatment conditions with a sample of n = 10 participants,produces an F-ratio of F = 5.40.For this result,which of the following is the correct statistical decision?

In a two-factor ANOVA,which of the following is not computed directly but rather is found by subtraction?

How many separate groups of participants would be needed for an independent-measures,two-factor study with 3 levels of factor A and 4 levels of factor B?

When using the Scheffé post hoc test for a repeated-measures ANOVA,the denominator for the F ratio should be _____.

The denominator of the repeated-measures F-ratio is intended to measure differences that exist without any systematic treatment effect or any systematic individual differences.

For a research study with 2 levels of factor A,3 levels of factor B,and n = 5 in each treatment condition,what are the df values for the F-ratio evaluating the main effect for factor A?

For the following data,what is SS_total?

Whenever a two-factor experiment results in a significant interaction,you should be cautious about interpreting the main effects because an interaction can distort,conceal,or exaggerate the main effects of the individual factors.

For an experiment involving 2 levels of factor A and 3 levels of factor B with a sample of n = 5 in each treatment condition,what is the value for df_within?

In a two-factor analysis of variance,a main effect is defined as _____.

If a two-factor analysis of variance produces a statistically significant interaction,what can you conclude about the main effects?
