When the problem objective is to compare more than two populations,the experimental design that is the counterpart of the matched pairs experiment is called the randomized block design.

Randomized Block Design

An experimental design used to reduce the variability among experimental units by grouping them into blocks before randomly assigning treatments.

Matched Pairs Experiment

A statistical study design in which pairs of subjects are closely matched based on specific variables, and each pair is treated differently to compare outcomes.

Compare Populations

The statistical process of analyzing two or more groups to determine if there are significant differences between them, often through hypothesis testing or variance analysis.
