Independent Random Sampling

A method of sampling where each member of the subset is chosen randomly and entirely by chance, ensuring that every subset of the population has an equal opportunity of selection.

Pooled Estimator

A method to estimate a common mean or variance from several different populations by combining or pooling sample statistics.

Pairwise Comparisons

A process of comparing entities in pairs to judge which is preferred or has a greater amount of some quantitative property.
