The Spearman Rank Order Correlation Coefficient. Spearmans correlation coefficient ρ also si. The test is used for either ordinal variables or for continuous data that.
The Spearmans rank coefficient of correlation is a nonparametric measure of rank correlation statistical dependence of ranking between two variables. It is given by the following formula. It can be any value from -1 to 1 and the closer the absolute value of the coefficient to 1 the stronger the relationship.
Spearmans correlation coefficient Spearmans correlation coefficient is a statistical measure of the strength of a monotonic relationship between paired data.
Spearmans rank correlation coefficient is the more widely used rank correlation coefficient. In a monotonic relationship the variables tend to change together but not necessarily at a constant rate. Use Spearmans correlation for data that follow curvilinear monotonic relationships and for ordinal data. The test is used for either ordinal variables or for continuous data that.
