Vol. 4, No. 11
Miwerds, owner of a chain of three
fabric stores called Sew Ôn Sew, is convinced that if he could just
persuade employees of the value of using statistics in quality
improvement, his customers would be happier and his profits higher. He
imagines being able to expand Sew Ôn Sew's reach to every city in
the state, then going public in order to channel investments into
further expansion efforts. 'Just think, ' he says to a co-worker,
'we could be in a position of winning the first Baldrige Award for
fabric retailing! ' The co-worker, more skeptical of the possibilities,
advises him to start with the home store, and see how the whole thing
goes from there.
Mark is highly confident about simple
statistics, as long as everything fits the formula and no one asks
questions. In this case, however, someone does ask a question.
'Why are you dividing the squared deviations from the mean by n ø 1
instead of n? '
