  • How to Interpret Standard Deviation in a Statistical Data

    The smallest possible value for the standard deviation is 0, and that happens only in contrived situations where every single number in the data set is exactly the same (no deviation). The standard deviation is affected by outliers (extremely low or extremely high numbers in the data set). That鈥檚 because the standard deviation is based on the distance from the mean. And remember, the mean is also affected.
