A comparison of the Pearson and Spearman correlation methods
The Spearman correlation evaluates the monotonic relationship between two continuous or ordinal variables. In a monotonic relationship, the variables tend to change together, but not …
Calculate Spearman's rank correlation coefficient - Minitab

Interpret the key results for Correlation - Minitab
Complete the following steps to interpret a correlation analysis. Key output includes the Pearson correlation coefficient, the Spearman correlation coefficient, and the p-value.
Methods and formulas for correlation - Minitab
To calculate Spearman's correlation coefficient and p-value, perform a Pearson correlation on the ranks of the data. The ranks of tied responses are the average of the ranks of the ties.
Interpret all statistics and graphs for Correlation - Minitab
The following plots show data with specific Spearman correlation coefficient values to illustrate different patterns in the strength and direction of the relationships between variables.
Select the analysis options for Correlation - Minitab
Use the Spearman correlation coefficient (also known as Spearman's rho) when the relationship between variables is not linear. The Spearman correlation measures the monotonic …
Overview for Correlation - Minitab
You can choose between two methods of correlation: the Pearson product moment correlation and the Spearman rank order correlation. The Pearson correlation (also known as r), which is …
Which regression and correlation analyses are included in
Use to calculate Pearson's correlation or Spearman rank-order correlation (also called Spearman's rho). In Minitab, choose Stat > Basic Statistics > Correlation.
What are Spearman's rho and Pearson's r for ordinal categories?
Use Spearman's rho and Pearson's r to assess the association between two variables that have ordinal categories. Ordinal categories have a natural order, such as small, medium, and large.
Methods and formulas for correlation coefficients for
Spearman's rho is a measure of the linear relationship between two variables. Spearman's differs from Pearson's correlation only because the computations are done after the numbers are …
