The scatterplot that represents the monthly values of stock QRS has an r value of

D

Step-by-step explanation:

The correlation coefficient, r value, measures the strength and direction of 2 variables in a scatterplot. It ranges from +1 to -1.

+1 means a perfect positive correlation

-1 means a perfect negative correlation

0 means there is no correlation

Also,

a value close to 0.7 would signify a strong relationship (whether positive or negative)

a value close to 0.5 indicates a moderate relationship

a value close to 0.3 indicates a weak relationship

Now, the question says the r value is 0.315

THis is POSITIVE

Also, this is a "weak" relationship

Thus, we can say:

It has weak correlation, or answer choice D
