In short, a lower standard deviation means that the elements of the set are clustered more closely around the mean. The standard deviation is particularly useful when working with normally distributed data, but it can be used to make useful inferences about all kinds of statistics. ...
Six Sigma is a set of techniques and tools used to improve business processes. It was introduced in 1986 by engineer Bill Smith while working at Motorola.
