18.104.22.168 - 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.
- Open the data set:
- On a PC: Select Statistics > Correlation > Correlation
On a MAC: Select Statistics > Regression > Correlation
- Double click the Quiz_Average and Final in the box on the left to insert them into the Variables box
- Click OK
This should result in the following output:
|Pearson correlation of Quiz_Average and Final = 0.608630|
|P-Value = <0.0001|
