Note: For charts created with the Control Chart platform instead of Control Chart Builder, replace 3 in the formulas with k.

Note: For sample sizes up to n = 50, JMP uses control chart constants d2(n) and d3(n) that are defined in Table 2 of Harter (1960). For samples with a sample size greater than 50, JMP uses the control chart constant values for sample size 50 in both the sigma and control limit calculations.
