Question
1. True or False? TF For a two-factor experiment, the bigger the differences between the group means, the more likely it is that at least one of the F- ratios will be significant. T F If the interaction in a Two-way ANOVA is significant, then at least O T FIf the F-ratio for factor A has df (2, 24) then the F-ratio for factor B O T F The bigger a treatment effect is, the larger the effect size will be. one of the two main effects also must be significant. also must have df (2, 24) I 2. In a two-factor experiment, the F-value for factor A has df-1, 30 and the F- | value for factor B has df = 2, 30. There were participants in this experiment b. 30 c. 33 d. 36 O three of the treatment means are essentially identical and one is substantially different from the others. This pattern of results would produce O a. a main effect for factor A b. a main effect for factor E S3. In a two-factor experiment with 2 levels of factor A and 2 levels of factor B c. an interaction between A and B d. all of the above 4. If Factor A has 3 levels and Factor B has 4 levels, the number of groups in the a. 3 experiment is O b. 4 2. C. 2Explanation / Answer
For an independent-measures two-factor experiment, the bigger the differences between the sample means, the more likely it is that at least one of the F-ratios will be significant.
Answer- True
If the i interaction in a Two way ANOVA is significant, then at least one of the two main effects must also be significant.
Answer-False.
If the F-ratios for factor A has df = 2,24 then the F-ratio for factor B will also have df = 2,24
FALSE.
explanantion: If the F-ratios for factor A has df = 1, 24 and the F-ratio for the interaction has df = 2, 24, then the F-ratio for factor B will also have df = 2, 24.
the bigger a treatment effect is, the larger the effect size will be. True.
please post remaining questions saperately. Thanks and God Bless Toy:)
