Question

Suppose the correlation between two variables x and y is. 8. That means the correlation between y and x is -. 8.

Answer 1

The given statement about the correlation between two variables is; False

Pearson's correlation coefficient

Pearson's correlation coefficient is the measure of linear correlation between two sets of data.

Pearson's r is always between the values of -1 and +1.

In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.

Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.

Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.
