D value in statistics

WebJun 18, 2015 · The reason we do so is simple. The value of d2 when k=30 is close to the value of d2 derived from a continuous distribution of subgroups having the same subgroup size. This is why the table of d2 values is published up to k =15. Control charts use range statistics and d2 values to estimate the standard deviation to compute control limits.
