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

A researcher conducts a 2 $\times$ 3 between-subjects ANOVA.She finds a significant interaction,where = 120 and = 518.What is the effect size for this test using eta-squared?

Which source of variation,if significant,is typically analyzed first?

A researcher computes a 2 $\times$ 3 factorial ANOVA.In this example,how many interactions can be observed?

A researcher computes a 3 $\times$ 4 between-subjects ANOVA.What are the degrees of freedom for Factor A for this study?

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

For an analysis of variance,the term "two-way" refers to

Eta-squared is a more powerful estimate of effect size than R².

Which of the following correctly identifies each source of variation in the two-way between-subjects ANOVA?

The following APA summary of a significant interaction is correctly stated: "The interaction between playfulness and resiliency was significant,F(16)= 3.07,p < .05 (R² = .12).

There are two factors and four cells in a 2 $\times$ 2 between-subjects ANOVA.

The assumptions for a two-way between-subjects ANOVA apply only to main effect tests,and not the interaction test.

A researcher conducts two studies using the two-way between-subjects ANOVA.The sum of squares total is smaller in Study 1 than in Study 2;the sum of squares for Factor A is the same in both studies.In which study will the effect size be larger for Factor A using omega-squared?

Which of the following describes a research design in which one factor could be a between-subjects factor,and the second factor could be a within-subjects factor?

To summarize any type of two-way ANOVA,we report the test statistic,the degrees of freedom,and the p value for each significant main effect and interaction.

A researcher computes a 3 $\times$ 4 between-subjects ANOVA and finds one significant main effect and a significant interaction.What is the next appropriate step?

A researcher records the amount of time spent studying by male and female college students in a dormitory versus a library setting.Different participants were observed in each group.What type of statistical design is appropriate for this study?

A two-way between-subjects ANOVA is appropriate for analyzing differences in the combination of levels for two or more factors.

Computing a two-way between-subjects ANOVA is appropriate when

Which of the following hypotheses identifies a prediction that requires that two factors we observed in the same statistical design?

A researcher has participants complete a survey regarding their level of restraint when eating.Participants were assigned to groups based on their current health status (lean,overweight,obese)and gender (male,female).What type of factorial design is most appropriate for this study?
