Click to chatA deviation is an unplanned event and can be caused by many factors among them Failure of equipment. Process variations contamination. Extra-ordinary environmental events. Lack of training. Undue care and attention. Insufficient resources A deviation would normally be considered an undesirable variation from an approved specification or

Click to chatStandard Deviation is a measure which shows how much variation (such as spread dispersion spread ) from the mean exists. The standard deviation indicates a "typical" deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Click to chatStandard deviation (StDev) plays an important role for any process improvement under the guidelines of a six sigma approach or quality initiative since is a measure of variability smaller it is closer the data are disperse around the mean. The mean could be any expected value or target.

Click to chatMean and Standard Deviation. The mean indicated by μ (a lower case Greek mu) is the statistician s jargon for the average value of a signal.
