WebbTo make it easier to write down these lengthy sums, we look at some new notation here, called sigma notation (also known as summation notation). The Greek capital letter \(Σ\), sigma, is used to express long sums of values in a compact form. For example, if we want to add all the integers from 1 to 20 without sigma notation, we have to write WebbThree-sigma limits is a statistical calculation where the data are within three standard deviations from a mean. In business applications, three-sigma refers to processes that operate efficiently and produce items of the highest quality. Three-sigma limits are used to set the upper and lower control limits in statistical quality control charts.
