Data Classification, Sampling, and Collection in Six Sigma

Before a Six Sigma team can begin to improve an organization's processes, it must measure key performance indicators. In doing so, the team identifies, collects, and analyzes data related to the processes. This course introduces basic types of data, such as continuous and discrete data, as well as various measurement scales. You will learn how to plan data collection and how to use data sampling techniques and data collection tools, such as check sheets. This course is aligned to the ASQ Body of Knowledge and is designed to assist Green Belt candidates toward achieving their certification and becoming productive members of their Six Sigma project teams.
