In statistics, a rank correlation is any of several statistics that measure an ordinal association —the relationship between rankings of different ordinal variables or different rankings of the same variable, where a "ranking" is the assignment of the ordering labels "first", "second", "third", etc. That is, if a scatterplot shows that the relationship between your two variables looks monotonic you would run a Spearman's correlation because this will then measure the strength and direction of this monotonic relationship. In some cases your data might already be ranked, but often you will find that you need to rank the data yourself (or use SPSS Statistics to do it for you). A monotonic relationship is not strictly an assumption of Spearman's correlation. In the figures below various samples and their corresponding sample correlation coefficient values are presented. For each observation in sample 1, count the number of observations in sample 2 that have a smaller rank (count a half for any that are equal to it).

The Spearman rank-order correlation coefficient (Spearman’s correlation, for short) is a nonparametric measure of the strength and direction of association that exists between two variables measured on at least an ordinal scale. The following example uses the Order function, rather than the Rank function, to rank the members of the City hierarchy based on the Reseller Sales Amount measure and then displays them in ranked order.
