The following table represents the order of administering the conditions to participants in a repeated measures experiment using an incomplete design in which the independent variable was the difficulty level of a children’s electronic puzzle game. Four-year-old children used a tablet to play a game requiring them to find hidden figures in three difficulty levels. The levels of difficulty were defined by the size of the figures embedded in the pictures displayed on the screen: extremely small (ES), very small (VS), and small (S). The dependent variable was the number of figures found by a child at each of the three difficulty levels (maximum = 10). Six children were tested, and the values in the table indicate the number of figures found at each level of difficulty. Use the table to answer the questions below.

A. What method was used to balance practice effects in this experiment?

B. Present the values you would use to describe the overall effect of the difficulty variable.

Include a verbal description of the effect along with the descriptive statistics that you use as a basis of your description.

C. What claim would you make about the effect of the difficulty variable if the probability associated with the F -test for the effect of the difficulty variable was p = .04?
