Exam 14: Chi-Square Tests: Goodness of Fit and the Test for Independence

A researcher observes the same participants across the levels of one factor and different participants across the levels of a second factor.What type of factorial design is most appropriate for this study?

A researcher computes a two-way between-subjects ANOVA and finds a significant main effect of Factor A and an A $\times$ B interaction.Which significant effect should be analyzed first?

Homogeneity of variance is one assumption for the two-way between-subjects ANOVA.

A ____ is the combination of one level from each factor.

Using an A $\times$ B ANOVA,a researcher concludes that Factor A is significant,independent of Factor B.In this study,this researcher found a significant

Simple main effect tests are necessary to analyze a significant interaction or a significant main effect.

The denominator of the formula for eta-squared is for both main effects and the interaction.

For the effects of a two-way between-subjects ANOVA,which values must be known to compute effect size using eta-squared?

A complete factorial design is one in which each level of one factor is combined or crossed with each level of the other factor.

A researcher randomly assigns different participants to each combination of levels for two factors.In this example,a two-way between-subjects ANOVA is appropriate to analyze the data.

A researcher computes a 2 $\times$ 3 between-subjects ANOVA in which 6 participants are observed in each cell.What are the degrees of freedom error for this study?

A researcher computes the following 2 $\times$ 3 between-subjects ANOVA,in which 11 participants were observed in each group.Which effect was significant at a .05 level of significance using the two-way between-subjects ANOVA?

A researcher computes a 3 $\times$ 5 between-subjects ANOVA.What are the degrees of freedom for the A $\times$ B interaction for this study?

For a two-way ANOVA,the ________ should also be reported for each significant hypothesis test and for the simple main effect tests.

The following APA summary of a significant main effect is correctly stated: "The main effect of comprehension level was significant,F(2,30)= 3.07,p < .05 (R² = .18).

Using a two-way between-subjects ANOVA with Factor A (Gender: male,female)and Factor B (Type of employment: blue collar,white collar),a researcher found that scores for men and women significantly varied across the levels of the second factor (type of employment).In this study,the researcher found a significant

An estimate of effect size with the two-way ANOVA is typically reported for:

There are ____ cells or groups in a 3 $\times$ 4 ANOVA design.

A researcher computes a 2 $\times$ 3 between-subjects ANOVA test in which 11 participants were observed in each condition.If F = 5.17 for both main effect tests and the A $\times$ B interaction test,then the decision for each test

A two-way ANOVA is a statistical procedure used to test hypotheses concerning the variance of two group means for the levels of one factor.
