The correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of r ranges from -1 to 1. r = 0 indicates no linear correlation between the variables. However, r obt (obtained value) not being equal to zero simply means there is some degree of linear correlation, which does not preclude r itself from being zero in a hypothetical or null hypothesis scenario where there is no correlation.
