The course presents 7 short videos with supporting downloadable Excel files to teach you the statistics, formulas, and concepts needed to understand how to perform and evaluate a Crossed ANOVA Gage R&R study which is required as part of the PPAP or many Quality Management System processes. What is Gage R&R? When to do Gage R&R When to Repeat Gage R&R Types of Gage R&R Methods (Xbar – R vs. ANOVA) Sum Function (Σ) Population vs. Sample Average/Mean (μ or x̅) Standard Deviation (σ or s) Variance Normal Distribution Galton Board Demonstration Normal Distribution Probability Density Function (PDF) Normal Distribution PDF Area Under the Curve Normal Distribution PDF Probability 68–95–99.7 rule F-Distribution Introduction F-Distribution Probability Density Function (PDF) F-Test One-Way ANOVA Null Hypothesis Calculate F-Statistic and P-Value One Way ANOVA Using Excel Two-Way ANOVA Gage R&R Study: 1. Collect data with multiple parts, operators, and replicates (retests) 2. Determine Alpha needed to ignore interaction term and Tolerance 3. Calculate Sum of Squares (SS) and Degrees of Freedom (df) for each group 4. Calculate Mean Squares for each group, (MS) = SS/df 5. Calculate F-Statistics, and P-values then Evaluate Significance of interaction 6. Calculate Variance Components, and Gage R&R Values 7. How to use the built in Two-Way ANOVA data analysis tool.
