A correlation of zero betwen two quamtative varibles means t

A correlation of zero betwen two quamtative varibles means that: A) there is no association between two varibles. B) There is no liner association between two varible. C) we have done something wrong in our calculation of r. D) Re-expressing the data will gurantee a linear association between the two varibles. E) none of the above.

Solution

The value of the correlation coefficient is between -1 and 1. Here -1 shows the perfect negative linear relationship (association) and 1 shows perfect positive linear relationship(association). And 0 shows no association between the variables. Hence, option A is correct.
