The null hypothesis for this example will be: Note that each individuals data is paired on a separate row so that their height and BMI are adjacent to each other. Thus, I want to see the strength of the correlation between the two variables by performing a Spearman rank correlation test. In this example, I have measured the height and body mass index (BMI) of 20 individuals. Finally, select the ‘ Create‘ button to open up the new sheet. Then, select the ‘ Enter and plot a single Y value for each point‘ option. To begin with, set-up the GraphPad sheet so that an ‘ XY‘ table and graph type is selected. This can be tested by plotting the variables on a scatterplot. There should be a linear relationship between the two variables.

The two variables should be measured on either an ordinal, interval or ratio scale.Assumptions of the Spearman rank correlation testīefore running the test, there are just 2 assumptions that the data has to pass. I will also show you how to interpret and report the results. In this article, I will show you how to perform a Spearman rank correlation test by using GraphPad Prism.
