Lean Six Sigma Green Belt

Ross Avilla discusses the 3 different varieties of Main effects: Positive Negative Null This example of a DOE is am experiment that includes the interaction of a drug and an associated therapy: https://youtu.be/1o4CO2mBmgU Ross Avilla

Chi-Square is a hypothesis tests that compares the observed values to the expected values. We discuss two types of Chi Square methods: Access the powerpoint slides

The Process of Design of Experiments is as follows: Access the powerpoint presentation: Lean Six Sigma Text Book: Read pages: Improve Phase –14-16 Design of Experiments –184-191 Failure Mode Effects Analysis (FMEA) –270-272 Pilot & Implement – 273-276

In this lecture, we will discuss analysis tools for use within our six sigma project to include: Access the presentation: Lean Six Sigma Text Book: Read pages: Analyze Phase -12-14 Correlation -173 Confidence intervals–156-160 Hypothesis Testing, T Test–162-164 F-Test –176 ANOVA –173-181 Chi Square–182-183

In this lecture, we will discuss hypothesis testing by first asking a research question. Access the powerpoint presentation:

Type I error (Alpha):  The null hypothesis was rejected, but all is well. Type II error (Beta): We failed to reject the null hypothesis and the consumer receives the problem-Consumer risk. Consumers will receive the defective product or service. To learn more: Hypothesis testing, type I and type II errors Amitav Banerjee, U. B. Chitnis, S. L. Jadhav, J.
