            • Step Deviation Method
          • Key Properties
            • Add constant: SD unchanged
            • Multiply by k: SD multiplied by k
        • Variance
          • Square of SD
          • Formula sigma squared
        • Coefficient of Variation
          • CV = sigma over xbar times 100
          • Compare consistency
          • Lower CV = more consistent
