Variance

In general, the population variance of a uniformly distributed finite population of size N is given by σ².

In many practical situations, the true variance of a population is not known a priori and must be computed somehow. When dealing with infinite populations, this is generally impossible.

A common task is to estimate the variance of a population from a sample. This is such a sample.

We are looking to embiggen this sample. Apply inside if you wish to increase sample size and thus ultimately the accuracy.
