The standard deviation of a sample is a measure of the spread of the sample from the mean. In a normal distribution, about 68% of a sample is within one standard deviation of the mean. About 95% is within two standard deviations. And about 99.7% is within three standard deviations. The numbers in this figure mark standard deviations from the mean.

Excel automatically calculated the average, the variance - which is the standard deviation, s, squared - and the essential probability information instantly. You can use this technique to compare physicians, nurses, hospital lengths of stay, revenue, expense, supply cost, days in accounts receivable, or any other factor of interest.
