3.4.2.3 - Minitab: Compute Pearson's r

Minitab®  – 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 file in Minitab: Exam.mwx (or Exam.csv)
  2. Choose Stat > Basic Statistics > Correlation.
  3. In Variables, enter Double click the Quiz_Average and Final in the box on the left to insert them into the Variables box
  4. Click Graphs.
  5. In Statistics to display on plot, choose Correlations and intervals.

This should result in the following:
