Thanks for taking the time to respond to my request. The information provided
was of help; however, it does not quite meet my need. What I am looking for
is a variant of a control chart; i.e., essentually a muti-dimensional control
chart. Analysis of Means, or ANOM, provides a way to determine the Upper and
Lower Natural Process limits whereby more than one variable can be evaluated
at a time as to whether its variation is more than be expected to happen by
chance alone. This is a valuable tool that has been growing in use however it
regretably is not currently part of the Excel data analysis package. Until
this deficency is corrected, or a workaround developed, the only recourse is
to purchase a spreadsheet program (such as minitab).
