Question

How should a researcher interpret the Pearson’s correlation coefficient?

Answer 1

Pearson’s correlation coefficient measures strength of linear relationship between two variable. It is denoted by r.

If r take positive value then there exist positive association between two variables if take negative value then there exist negative association between two variables. And if r = 0 then there is no correlation exist.

Value of r always lies between -1 to +1 . Value close to -1 and +1 indicate that high degree association, where as value close to zero indicate low degree association.
