Variance

Variance(list)

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

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

Variance can be applied to the following distributions:

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

Examples

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

>> Variance({7, -5, 101, 3})
7475/3

>> Variance({1 + 2*I, 3 - 10*I})
74

>> Variance({a, a})
0

>> Variance({{1, 3, 5}, {4, 10, 100}})
{9/2,49/2,9025/2}
