Eddy Current Probe Sensitivity Case Study

Analysis of a 2³ Full Factorial Design

This case study demonstrates the analysis of a 2³ full factorial design.

The analysis for this case study is based on the EDA approach discussed in an earlier section.

Contents

The case study is divided into the following sections:

1. Background and data
2. Initial plots/main effects
3. Interaction effects
4. Main and interaction effects: block plots
5. Estimate main and interaction effects
6. Modeling and prediction equations
7. Intermediate conclusions
8. Important factors and parsimonious prediction
9. Validate the fitted model
10. Using the model
11. Conclusions and next step
12. Work this example yourself
