An education researcher is interested in the ability of preschool children to solve math story problems. He wants to see if the method of presentation, either as verbal story problems or as visual story problems, makes a difference in preschoolers' abilities to solve the problems correctly. In an example of the verbal condition, a child is asked, "Two birds are sitting on a fence; two more birds fly down and join them. How many birds are on the fence altogether?" In an example of the nonverbal, visual equivalent of this problem, the experimenter presents the child with a picture of two birds on the fence with two birds in the process of landing on the fence and then asks the child, "How many birds are on the fence altogether?" In both conditions, the child responds orally. Shown below is the number of correct answers out of 10 problems for each child. What conclusions about the difference between a preschooler's ability to solve simple math problems presented either verbally or nonverbally can be made from these results?
