Answer:
(d) WEAK NEGATIVE ASSOCIATION.
Step-by-step explanation:
Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.
Here, r = -0.19
Now, as r is NEGATIVE.
⇒ As the value of x increases , value of y decreases.
⇒There is a NEGATIVE ASSOCIATION.
Now as the value of r is between 0 and ( -1). So the factor of variation is very small.
Hence, it is WEAK NEGATIVE ASSOCIATION.
