Examples of StandardDeviation

org.apache.commons.math.stat.descriptive.moment.StandardDeviation
Computes the sample standard deviation. The standard deviation is the positive square root of the variance. This implementation wraps a {@link Variance} instance. The isBiasCorrected property of thewrapped Variance instance is exposed, so that this class can be used to compute both the "sample standard deviation" (the square root of the bias-corrected "sample variance") or the "population standard deviation" (the square root of the non-bias-corrected "population variance"). See {@link Variance} for more information.
Note that this implementation is not synchronized. If multiple threads access an instance of this class concurrently, and at least one of the threads invokes the increment() or clear() method, it must be synchronized externally.
