CEVAP:

In order to show the degree of the relationship between two continuous variables, The Pearson’s correlation coefficient or Pearson’s product moment correlation coefficient is widely used. There are two symbols used for Pearson’s correlation coefficient, population correlation is represented by ? (rho) and sample correlation is represented by r. Pearson’s correlation coefficient gets values between -1 and +1. If the result is exactly -1 or +1 then there is a perfect relationship between the variables. The sign of the Pearson’s correlation coefficient indicates the direction of the relationship. The positive sign indicates that the change in the variables is in the same direction.
