If the control limits were very wide, +/- 8 sigma from the average, we would never make mistake No. 1. If they were very narrow, let’s say, +/- 0.1 sigma from the average, we would never make mistake No. 2. The 3-sigma limits balance the probability of making both these mistak...
Standard Deviationis a statistical measure of dispersion, or how spread out data is. It is calculated as the square root of the variance. The variance is the average of the squared differences from the mean. Itssymbol is σ (the greek letter sigma). Arithmetic Formula to Calculate Standard D...
