Notes:

• Control limits are calculated using a sigma multiplier, K, which is set to 3 by default. To change the default value of K, use the K Sigma option in the red triangle menu or the K Sigma preference in File > Preferences > Platforms > Control Chart Builder.

• 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.
