Question

The graph below plots the values of y for different values of X:

Which correlation coefficient best matches the data plotted on the graph? (1 point)

Answer 1

0.50

Explanation:

we know that

Observing the graph

we have the following points

(1,3),(2,4),(3,9),(4,7),(5,2),(6,18)

Using a Excel tool (Correl function)

The correlation coefficient is equal to r=0.605639

see the attached table

therefore

The correlation coefficient that best matches the data plotted on the graph is 0.50
