Question

what does it mean if r = 0?
choose the correct answer below.
a. no linear relationship exists between the variables
b. a relationship does exist between the variables
c. no relationship exists between the variables
d. a linear relationship does exist between the variables

Explanation:

The correlation coefficient \( r \) measures the strength and direction of a linear relationship between two variables. When \( r = 0 \), it indicates that there is no linear relationship. However, it does not rule out the possibility of a non - linear relationship.

Answer:

A. No linear relationship exists between the variables
