StandardDeviation

StandardDeviation(list)

computes the standard deviation of list. list may consist of numerical values or symbols. Numerical values may be real or complex.

StandardDeviation({{a1, a2, ...}, {b1, b2, ...}, ...}) will yield {StandardDeviation({a1, b1, ...}, StandardDeviation({a2, b2, ...}), ...}.

StandardDeviation can be applied to the following distributions:

BernoulliDistribution, BinomialDistribution, DiscreteUniformDistribution, ErlangDistribution, ExponentialDistribution, FrechetDistribution, GammaDistribution, GeometricDistribution, GumbelDistribution, HypergeometricDistribution, LogNormalDistribution, NakagamiDistribution, NormalDistribution, PoissonDistribution, StudentTDistribution, WeibullDistribution

See

Examples

>> StandardDeviation({1, 2, 3})
1


>> StandardDeviation({7, -5, 101, 100})
Sqrt(13297)/2


>> StandardDeviation({a, a})
0


>> StandardDeviation({{1, 10}, {-1, 20}})
{Sqrt(2),5*Sqrt(2)}


>> StandardDeviation(LogNormalDistribution(0, 1))
Sqrt((-1+E)*E)
