A materials engineer for a building products manufacturer is developing a new insulation product. The engineer designs a 2-level full factorial experiment to assess several factors that could impact the strength, density, and insulating value of the insulation.
You can use this data to demonstrate Analyze Factorial Design.
| Worksheet column | Description |
|---|---|
| StdOrder | The order of the runs in standard order (also called Yates order). |
| RunOrder | The order of the runs in random order. |
| CenterPt | The center points. This design has no center points. |
| Blocks | The blocks. In this design, all the design points are contained in a single block. |
| Material | Material type: Formula1 or Formula2 (factor). |
| InjPress | Injection pressure: 75 or 150 (factor). |
| InjTemp | Injection temperature: 85 or 100 (factor). |
| CoolTemp | Cooling temperature: 25 or 45 (factor). |
| MeasTemp | Temperature at the time of the response measurements (covariate). |
| Insulation | The insulating value (response). |
| Density | The density value (response). |
| Strength | The strength of the insulation (response). |
| Machine | The machine that created the insulation: 1, 2, 3, or 4. |
