Discussion:
Control charts are a simple way of doing fundamental statistics on random variables which are measured sequentially through time.
Go to any source available to you (like you did for "Statistics from My Interest Area") and review a use of control charts. (Search words: Your interest and control charts. If none show up choose another interest area.) Provide a cover page and one page of your comments on the control chart including naming and describing the variable and its type, the length of the data record, the "sigma limit" used and the criteria used for determining when the system was "out of control" and summarizing the conclusions developed in the article from the control chart. Provide no more than one page of material copied from the web or other source.
