What is the correlation coefficient for the data plotted? −0.9 −0.6 0.6 0.9

Answer 1

The correlation coefficient is -0.6

Explanation:

we know that

The correlation coefficient is a number between −1 and +1 calculated so as to represent the linear dependence of two variables or sets of data.

Using a Excel tool (Correl function)

The correlation coefficient is
`r=-068648`
