Suppose Alyse collected the following unusual data for students in her class:
a.
b.
shoe size
6
7½
8
8½
10
height (cm)
154
160
162
164
170
What is the correlation coefficient? In the context of this problem, what does
the correlation coefficient tell Alyse about the variation in heights?
What can Alyse say about the predicting height in her class?
