#3 and #5 3. In a 2 X 3 Anova, if a significant interaction occurs then...
In a two-factor ANOVA, a significant interaction means that at least one of the main effects is also significant. True or False?
ider the following graphic results from a 2 x 2 factorial experiment. These results show 100 A1 50 A2 a. there is a significant main effect for factor A, no other significant effects b. there is a significant main effect for factor B, no other significant effects c. there is a significant interaction effect, no other significant effects d. there is a significant main effect for factor A, a significant interaction effect, and no other significant effects e. there is...
If the A x B interaction is significant, then at least one of the two main effects also must be significant. Group of answer choices True False
If your main reason for choosing a 2 x 2 design is that the interaction is of particular interest, then the best analysis would be to examine a. the main effect of A and the main effect of B. b. the main effect of A, the main effect of B, and the interaction of A and B. c. the interaction of A and B and two simple main effects. d. the interaction. e. two simple main effects.
question 36 A researcher computes a 2 × 3 between-subjects ANOVA test in which 11 participants were observed in each condition. If F= 5.20 for both main effect tests and the A × B interaction test, then the decision for each test ______. a. There is not enough information to answer this question. b. will be significant for Factor B and the A × B interaction c. will be significant for both main effects and the A × B interaction...
QUESTION 44 In a two way ANOVA, how many effects (main effects and interaction) are tested? a. 4 b. 1 c. 3 d. 2 2 points QUESTION 45 Main effects are defined as the effect of ______. a. one independent variable on the dependent variable that changes at the different levels of another independent variable b. the dependent variable on the independent variable within a factorial research design c. an independent variable on the dependent variable within a factorial...
A 2^3 factorial is replicated twice. The ANOVA indicates that all main effects are significant but the interactions are not significant. The interaction terms are dropped from the model. The number of residual degrees of freedom for the reduced model is
Because there are only two possible hypothesis testing outcomes (significant or not) and there are two main effects and an interaction in a 2 x 2 factorial ANOVA, then there are _____ possible outcomes. a) 2 b) 4 c) 6 d) 8
478: There is strong interaction between two variables. This means that: A. An interaction occurs when the effect of one input factor on the output depends upon the level of another input factor B. An interaction occurs when there is a strong correlation between two factors C. An interaction occurs when the effect of one input factor on the output depends upon the level of the same input factor D. An interaction occurs when two or more factors are confounded...
A sociologist classified 45 faculty members by subject matter of course (factor A with 4 levels) and highest degree earned (factor B with 3 levels) The first ANOVA table below is from a model including A and B main effects and AB interaction effects. The second one is from a model including B main effects and AB interaction effects but no A main effects Sequential sum of squares ANOVA table with A, B and AB terms. Analysis of Variance Source...
