- Minitab Express to Compute Pearson's r

MinitabExpress  – Pearson's r

We previously created a scatterplot of quiz averages and final exam scores and observed a linear relationship. Here, we will compute the correlation between these two variables.

  1. Open the data set:
  2. On a PC: Select Statistics > Correlation > Correlation 
    On a MAC: Select Statistics > Regression > Correlation
  3. Double click the Quiz_Average and Final in the box on the left to insert them into the Variables box
  4. Click OK

This should result in the following output:

Correlation: Quiz_Average, Final
Pearson correlation of Quiz_Average and Final = 0.608630
P-Value = <0.0001
