Strong Positive Correlation. When the value of correlation coefficient is close to 1, then the correlation is described as strong positive correlation. Generally the values of r > 0.8 are considered to indicate strong positive correlation.
The most used correlation coefficients only measure linear relationship. It is therefore perfectly possible that while there is strong non linear relationship between the variables, r is close to 0 or even 0. In such a case, a scatter diagram can roughly indicate the existence or otherwise of a non linear relationship.
