For this recipe, we will use a 2-Sample t-test to compare two groups of data. The null hypothesis for the 2-Sample t-test is that the population means are the same.
Here, we will look at comparing the pulse rate of a group of students that exercised against a group that didn't.
The data is in the Minitab Pulse.mtw
worksheet. The file can be found in the Minitab Sample Data
folder.
The following steps will compare the mean pulse rate of two groups of students:
