Quality Excellence Hub The R chart is a measure of the short-term variation in the process. Subgroups should be formed to minimize the amount of variation within a subgroup. This causes the X chart to do the work in detecting process changes. Steps in Constructing an X-R Chart. The steps in constructing an X-R chart are given below. 1. Gather the data. a. Once the R chart exhibits control (such as the above chart), then an out of control condition on the Xbar chart is a result of changes in the process center. The first data point is the difference in the maximum and minimum of the 5 observations in the first subgroup of 23.2, 24.2, 23.6, 22.9, 22.0. This template contains a pre-made control chart for sample Mean and Range, or sample Mean and Standard Deviation (2 worksheets in one). Just add your own data. Control limits are calculated based on the data you enter. - Evaluate process capability (Cp, CPU, CPL, Cpk, and % Yield) for given specification limits.
