Control Limit in Excel (With Formulas) How to Make and Use a C Chart GoSkills Upper & Lower Control Limit Calculator WebCreate a control chart in Excel. .LCL = Average (X) – 3*Sigma (X) where Average (X) = average of all the individual values and Sigma (X) = the standard deviation of the individual values. If you are plotting subgroup averages (e.g., the Xbar control chart), the control limits are given by: UCL = Average (Xbar) + 3*Sigma (Xbar) The control limits of your control chart represent your process variation and help indicate when your process is out of control. Control limits are the horizontal lines above and below the center line that are used to judge whether a process is out of control. The upper and lower control limits are based on the random variation in the process.And it can be estimated using the average range (Rbar) between samples (Rbar/d2) when the number of subgroups is 2-10, or using standard deviation Sbar/c4 when n>10.
