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.
â¢ Both correlation and covariance are measures of relation between two random variables. Correlation is the measure of strength of the linearity of the two variables and covariance is a measure of the strength of the correlation.â¢ Correlation coefficient values are a value between -1 and +1, whereas the range of covariance is not constant, but can either be positive or negative.t is the most commonly used correlation coefficient and valid only for a linear relationship between the variables. If r=0 no relationship exist, and if râ¥0 the relation is directly proportional; the value of one variable increases with the increase of the other.
