1. Verbal ability consists of at least two components: verbal comprehension (e.g., reading ability) and verbal fluency (e.g., writing ability). A researcher measures these two components in a sample of 8 seventh-grade children and obtains the following scores: Comprehension 7 74 42 48 7562 76 69 57 Fluency. 40 46 38 36 54 42 50 25 a) Is there a significant correlation between the two variables (a ≤.05)? b) If another seventh-grader obtained a verbal comprehension score of 70, what would his or her predicted verbal fluency score be?
