The Spearman's Rank Correlation Coefficient is used to discover the strength of a link between two sets of data. This example looks at the strength of the link between the price of a convenience item (a 50cl bottle of water) and distance from the Contemporary Art Museum in El Raval, Barc...
Scale of measurement must be ordinal (or interval, ratio) Data must be in the form of matched pairs The association must be monotonic (i.e., variables increase in value together, or one increases while the other decreases) Equation

It is the nonparametric rank-based correlation method. It evaluates the prediction monotonicity by using the following equation [69]: (8)SROCCX,Y=1−6∑i=1ndi2nn−1 where di is the difference between each pair of values in X and Y; and n is the total number of data pairs. In ...
Spearman. The author explains Spearman's correlation coefficient and its application to data rankings and epidemiological studies of chance, bias, and confounding. It highlights the attenuation errors, some formulas for correction and the early versions of the Spearman-Brown equation. It also provides ...

In conclusion, the results of my investigation indicate that the Pearson's correlation coefficient could have significant advantages for continuous non-normal data which does not have obvious outliers. Thus, the shape of the distribution should not be a sole reason for not using the Pearson product...
