During the Analyze phase of a Lean or Lean Six Sigma improvement project, the team conducts a number of statistical analyses to determine the nature of variables and their interrelationships in the process under study. This can in turn lead to business process improvement. In this course, you'll learn about some of the basic concepts relating to hypothesis testing, and how it can drive process improvement, process control, and process design. You'll also explore how to carry out various types of hypothesis test design, to find and compare means. The course is aligned with ASQ's 2015 Six Sigma Green Belt Body of Knowledge.
