  The equi-depth histogram problem is obviously akin to that of quantiles [9], which seeks to identify the item that occupies a given position in a sorted list of N items: Thus given a ϕ, 0 ≤ ϕ ≤ 1, that describes the scaled rank of an item in the list, the quantile algorithm must return the ⌈ϕN⌉’s item in the list. For example, a

  Once you have run a histogram to calculate Cp and Cpk, you can decide how to improve. If the process is off-center, adjust your work so that it becomes centered. If the capability is less than 1.33, adjust your process so that there is less variation. In manufacturing, customers require Cp=Cpk greater than 1.33 (4-Sigma).
