Question 6.31
31. A high school teacher conducted a small study on school achievement. For a group of 20 of her juniors, she recorded the number of days the students attended school in their junior year and their grade point average at the end of the year. A scatterplot of her data appears in Figure 6.21. Would you describe the relationship between GPA and Days Attended as positive, negative, or neither? Briefly explain.

It's a positive association; as number of days attended increases, GPA tends to increase.
