Overview/Description
During the Analyze stage of a Six Sigma project, teams use statistical tools such as correlation analysis, regression analysis, and hypothesis testing. An improvement project can greatly benefit from these tools. They provide information regarding which key inputs are affecting outputs and how to tweak inputs until the desired results are achieved. Then new results can then be tested to ensure the changes are due to the changes that were implemented. The course examines correlation analysis, regression analysis, and hypothesis testing. This course is aligned to the ASQ Body of Knowledge and is designed to assist Yellow Belt candidates toward their certification and also to become productive members on their Six Sigma project teams.

Target Audience
Candidates seeking Six Sigma Yellow Belt certification and any other individuals involved in quality and process improvement at the organizational or departmental level

Prerequisites
None
