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.
|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.|
