Week Two
Measure Phase
✓ 1. Introduction
✓ 2. Clarify the Process/Product & Customer CTs
✓ 3. Characterize the Defect
✓ 4. Determine Measure of Intended Function
Analyze 4 Identify causes (Xs) of variation and defects. 5 Provide statistical evidence that causes are real.
Improve 6 Determine solutions (ways to counteract causes) including operating
ANOVA is used to:
▪ Identify sources of variability in Y. ▪ Verify that suspected causes are real. ▪ Determine the significance of a regression equation. ▪ Determine which factors affect the output in a DOE.
About This Module
Analyze 4 Identify causes (Xs) of variation and defects. 5 Provide statistical evidence that causes are real.
Why do we conduct ANOVA testing? ANOVA (Analysis of Variance) tests the statistical significance of the differences among the obtained means of two or more random samples from a given population.
