Question 1
Two-way ANOVAs are used when we have multiple dependent variables in our design.

True

False

Question 2
In a factorial design multiple independent effects are tested simultaneously.

True

False

Question 3
Consider these two tables of cell means. Which one shows evidence of a possible interaction?

Table 1

Table 2

Question 4
The two-way ANOVA results in the calculation of three F-ratios.

True

False

Question 5
A 3 x 3 analysis of variance was conducted to examine the effect of race and type of course on university students’ sense of community. The results of the interaction effect revealed,F(2,58) = 1.84, p = .50, observed power = .56. The results for the main effect for course were, F(2, 58) = 7.56, p = .01, η2 = .02.  The results for the main effect for race were F(2, 58) = 2.54, p = .22,η2= .001. How can these results be interpreted?

An 3 x 3 analysis of variance demonstrated that the interaction effect was not significant. The main effect for race and type of course  did not reach statistical significance.

An 3 x 3 analysis of variance demonstrated that the interaction effect was not significant. There was a statically significant main effect for type of course and race.

An 3 x 3 analysis of variance demonstrated that the interaction effect was not significant. There was a statically significant main effect for type of course. The main effect for race did not reach statistical significance.

An 3 x 3 analysis of variance demonstrated that the interaction effect was not significant. The main effect for type of course did not reach statistical significance. There was a statically significant main effect for race.

Question 6
A histogram is used for what purpose when conducting  a two-way ANOVA?

The normality assumption

The significance of the test

The homogeneity of variance assumption

The assumption of extreme outliers

Question 7
A two-way ANOVA can be used in experimental and quasi- experimental studies.

True

False

Question 8
Joe wanted to test the following research question:

Is there difference in course points of male and female graduate students’ who are using (video conferencing, audio conferencing, or discussion board) in their online course?

What type of design would he use?

2 X 3

2 x 6

3 X 3

Question 9
When the lines in a graph of the cell means intersect in a two-way ANOVA, you can conclude that:

neither the main effect for factor A nor factor B is statistically significant.

main effects for factor A and factor B are statistically significant.

the interaction effect of factor A and factor B is statistically significant.

the assumption of homogeneity of variance within groups has been violated.

Question 10
In planning a study involving a two-way ANOVA, which is nottrue:
