Enter your data for Analyze Variability

Stat > DOE > Factorial > Analyze Variability

In Response (standard deviations), enter the column of numeric data that you want to explain or predict with the factors.

In this worksheet, Std is the response and contains the standard deviation values that were generated by Pre-Process Responses for Analyze Variability. N is the number of repeats. Strength_1 to Strength_6 contains the repeat measurements of strength at each combination of factor settings.

Note

When Minitab fits a linear model to the data, it transforms the standard deviations using the natural log.
