Answer:
weak negative
Explanation:
we know that
The correlation coefficient r measures the direction and strength of a linear relationship. It can take a range of values from +1 to -1.
Values between -0.5 and -1.0 or 0.5 and 1.0 indicate a strong negative/positive linear relationship
Values between -0.3 to -0.1 or 0.1 to 0.3 indicate a weak negative/positive linear relationship
In this problem
The correlation coefficient for the data is −0.31
therefore
Is a weak negative correlation
