standard deviation


In statistics, a measure of how much the data in a certain collection are scattered around the mean. A low standard deviation means that the data are tightly clustered; a high standard deviation means that they are widely scattered.	1
‡ About sixty-eight percent of the data are within one standard deviation of the mean.	2
