Course Overview
Statistical thinking is necessary in any effective process improvement endeavor in any organization. All business improvement professionals know how important sound quantitative analysis is, yet statistics can be challenging to learn and use properly.
Throw on top of that a complex statistical analysis software package that you also need to learn and remember, and suddenly you find the whole concept very challenging to use. The ability to make low risk decisions using only samples of data will come to the fore with the growing need to improve faster and compete more effectively.
That's why this Minitab Statistical Analysis course was put together to remove the pain of finding different functions and trying to remember how to use them for the purpose of providing business improvement practitioners and line managers with a simple guide to the use of Minitab Software in the application of the statistical analysis tools of Six Sigma.
