Bar charts can also be used with numeric responses. Using the graphs with the selected function of a variable, we can find the mean of a numeric column. Here, we will use the pulse data to see the difference in the mean pulse rate for the previous and next activity columns. We will also split the bars into those who ran on the spot and those who didn't.
The following instructions will create a bar chart of Pulse1
and Pulse2
clustered together within the Ran
column:
Go to the File menu and select Open Worksheet….
Click on the button labeled Look in Minitab Sample Data folder.
Open the
Pulse.MTW
worksheet.Go to the Graph menu and select Bar Chart….
Change the selection for Bars represent: to A function of a variable.
Select the Cluster bar chart under Multiple Y's and select OK.
Make sure the Function: section is set to Mean and then select the Graph variables: section. Enter
Pulse1
andPulse2
into the graph variables.
