Definitions:

Sample Variance

Sample variance is a measure of the dispersion or variability of a sample dataset, calculating how much the numbers differ from the sample mean.

Consistent

A statistical property indicating that as the size of the sample increases, the estimator converges in probability to the parameter being estimated.

Unbiased Estimators

Statistical estimators that, on average, accurately predict the value of a population parameter without systematic error.

Smallest Variance

The smallest degree of spread or dispersion of observations around the mean in a dataset, indicating less variability.
