In a monotonic relationship, the variables also tend to change together, but not necessarily at a constant rate. Spearman Rank Correlation evaluates the monotonic relationship between the ranked values. Linear means a relationship when two variables change in the same direction at a constant rate. The Pearson Product Moment Correlation tests the linear relationship between two continuous variables. The Spearman correlation is the nonparametric version of the Pearson correlation coefficient that measure the degree of association between two variables based on their ranks.

Do Spearman correlation in Excel using a graph.

Find Spearman correlation coefficient with traditional formula.

Calculate Spearman correlation coefficient with Excel CORREL function.

In such circumstances, you can do the Spearman rank correlation instead of Pearson's. But because the Pearson correlation coefficient measures only a linear relationship between two variables, it does not work for all data types - your variables may be strongly associated in a non-linear way and still have the coefficient close to zero. When doing correlation analysis in Excel, in most cases you will deal with the Pearson correlation. The tutorial explains the basics of Spearman correlation in a simple language and shows how to calculate the Spearman rank correlation coefficient in Excel.
