WebStandard Deviation (also known as Sigma or σ) determines the spread around this mean/central tendency. The more number of standard deviations between process average and acceptable process limits fits, the less likely that the process performs beyond the acceptable process limits, and it causes a defect. This is the reason why a 6σ (Six Sigma ...
