WebUCL = Upper Control Limit. LCL = Lower Control Limit. Control Limits are calculated based on the amount of variation in the process you are measuring. One measure of variation is standard deviation*. A common method of calculating control limits is the mean +/- three standard deviations. How is LCL freight calculated? Web1 feb. 2024 · Since the population standard deviation, σ, is not known, an estimate of it is used.
