In a mixed design factorial ANOVA, the between subjects factor (A) has two levels and the repeated measures factor (B) has three levels. A significant F is found for the main effect of the repeated measures factor. We may conclude that _____.
 
  a. The means of the levels of Factor B are all different from one another
  b. There is a significant difference in the means for Factor B, but we don't know where
  c. The mean of Factor A is significantly different from the mean of Factor B
  d. The interaction between A and B is significant

Question 2

In a mixed design factorial ANOVA, the between subjects factor (A) has two levels and the repeated measures factor (B) has three levels. A significant F is found for the main effect of the between subjects factor. We may conclude that _____.
 
  a. the mean of level 1 of factor A is significantly different from the mean of level 2 of Factor A
  b. There is a significant difference, but we don't know where it is.
  c. The mean of Factor A is significantly different from the mean of Factor B
  d. The interaction between Factors A and B is significant.

Answer to Question 1

B
The significant F tells us that there is a significant difference between the means of the three levels of Factor B, but it doesn't tell us which means are different and which means are not.

Answer to Question 2

A
The significant F means that there is a difference between means. Because there are only two levels of Factor A, we know that the means for these two levels must be significantly different.
