Question

Suppose you find that the correlation coefficient for a set of data is 0.826. What is the coefficient of determination and what does it mean?

Answer 1

`r^2 = 0.826^ 2 =.6822`

`r^2 =` a measure of how strong the ("how fit") the relationship is

it is always positive between 0 and 1

Explanation:

coefficient of determination = r^2

r^2 = 0.826^ 2 =.6822
