Application Of Spearmans Rank Correlation. The Spearmans Rank Correlation Coefficient is the non-parametric statistical measure used to study the strength of association between the two ranked variables. Spearmans correlation in statistics is a nonparametric alternative to Pearsons correlation.
In a monotonic relationship the variables tend to change together but not necessarily at a constant rate. Spearmans Rank correlation coefficient is a technique which can be used to summarise the strength and direction negative or positive of a relationship between two variables. This method measures the strength and direction of association between two sets of data when ranked by each of their quantities and is useful in identifying relationships and the sensitivity of measured results to influencing factors.
It determines the degree to which a relationship is monotonic ie whether there is a monotonic component of the association.
Method - calculating. One after the other so that ranks can be given to each. This method is applied to the ordinal set of numbers which can be arranged in order ie. Let us plot a graph and visualize the data where the increase in GDP per capita is on the X-Axis and Suicides100k population is on the Y-AXIS.
