Before you use Analyze Variability, you must:
1 Create or define a 2-level factorial design that includes repeat or replicate measurements of your response.
2 Enter your response data into the worksheet following the instructions in Data - Pre-process Responses.
3 Store the standard deviations and number of repeats or replicates using Pre-process Responses.
You can fit a model with one response variable at a time. Minitab automatically omits missing data from the calculations.
