6.15 This line plot shows the number of books that a group of students have read. Use this data to determine where on the line plot the mean will appear. 68

x 69

6.15

This data shows the ages of members of a youth book club and the age of the facilitator What is the most appropriate measure of center for this data? 72

Sample answer: Median because the age of the facilitator is much higher than the ages of the other members, and there is no mode. 73

6.15a Jill recorded the number of pull-ups each of ten students did on this line plot. What is the balance point for this data? Pull-Ups Each X represents 1 student. Number of Pull-Ups X X X X X X XX X X 74

The balance point for this data is 5.
