When the relationship is non-linear in nature Spearman correlation or rank correlation is used in order to account for the deviation from linearity.

The proofs of these rules can be purchased for a nominal fee from the Order page.Correlation defined The covariance measure is scaled to a unitless number called the correlation coefficient which in probability is a measure of dependence between two variables.Dependence broadly refers to any statistical relationship between two variables or two sets of data.The step by step calculation for correlation coefficient example illustrates how the values are being used in the formula to find the linear correlation between the data sets.Correlation Coefficient is a vital aspect used in statistics to calculate the strength and direction of the linear relationship or the statistical relationship (correlation) between the two population data sets.

Correlation Coefficient is a vital aspect used in statistics to calculate the strength and direction of the linear relationship or the statistical relationship (correlation) between the two population data sets.

It measures the how strongly and in which direction the linear relationship between the the two data sets.
