1. Discuss the differences among the three major components of statistical
methodology (descriptive statistics, statistical inference, and predictive
statistics). Why might these distinctions be important to a manager? Respond
to at least two of your classmates’ postings.
2. In 1995 Jack Welch sent a memo to his senior managers telling them that
they would have to require every employee to have started Six Sigma training
to be promoted. Furthermore, 40 percent of the manager’s bonuses were to be
tied to the successful introduction of Six Sigma. Do you believe that this
directive was a motivational action, or did it violate W. Edwards Deming’s
maxim that managers and leaders must “cast out fear”? Why or why not?
