Section C02 (2010-09-16)

I was planning/hoping to spend a minute or two on plotting a MegaStat graph of 24 coffee temperature values in the Excel file on the course web site:

http://www.business.mcmaster.ca/courses/q600/ChapterComments/documents/CoffeeTemp.xls

As you remember, the system turned itself off at the end of the class and I couldn't show you the Excel file.

Here are the steps to follow to plot the graph (assuming that you have installed MegaStat):

Double-click on the file and start Excel | Add-Ins > MegaStat > Descriptive Statistics > Input Range (A2 to A25) > Choose Runs Plot > OK

Does the Runs Plot indicate that the process (coffee temps) is in statistical control, and capable?
