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?

-0.5
0
0.25
0.90

Answer 1

The given graph starts from down to up and forms a straight line. Thefor, the correlation coefficient that best matches the data plotted on the graph is 0.90.

Answer 2

Answer:

0.50

Step-by-step explanation:

Looking at the graph

we see the following points

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

The correlation coefficient is equal to r=0.605639

Therefore

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