Anova DOE

To check on significance influence of each factor in the DOE. If a factor is not significant it can bee pooled, and the influence of the non pooled factors is getting bigger. In the example only size is not pooled, but Size is still not significant.

Interpretation

• The smaller the p value is the more likely this factor has significant influence.
• Develve uses the commonly accepted value of p < 0.05 for significance.

Colors of the cells

• Green
  No significant difference
