The Rank Correlation Coefficient Varies Between. Correlation is a bivariate analysis that measures the strength of association between two variables and the direction of the relationship. Spearmans correlation in statistics is a nonparametric alternative to Pearsons correlation.
Spearmans Rank Correlation Coefficient This method is useful for correlation analysis when variables are expressed in qualitative terms like beauty judgment intelligence honesty etc. 1 indicates a perfect degree of association between the two variables. A ρ of 1 indicates a perfect association of ranks.
Rho varies between -1 and 1.
The coefficient is positive then both variables are increasing while negative. Compute the correlation between the two series of test scores by Rank Difference Method. Statistical measure of the linear association between two variables where both have been measured using ordinal rank order scales. Steps of Calculation of Spearmans Co-efficient of Correlation.
