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. Related to...

Six Sigma is the name given to one of the most widely used methodologies for improving efficiency and profitability in manufacturing and production processes. Its users are trained in the basics of statistics, problem solving and project management. Shirley Coleman tells us that Six Sigma is an ...
Re: Please explain six sigma in terms of statistics to me Hi this "1.5 sigma shift" thing is bothering much but this is the fact that this shift occurs if we observe the process on long time span. this is not because the process is going out of control but it is due to ...
