Insulation properties data

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.

You can use the data with the model to demonstrate the following factorial commands:
  • Predict
  • Factorial Plots
  • Cube Plot
  • Contour Plot
  • Surface Plot
  • Overlaid Contour Plot
  • Response Optimizer
Tip

To view a summary of the design, choose Window > Project Manager then click the design in the folder for the worksheet.
