Utilizes non-parametric statistical analysis to pinpoint variations in treatments through successive testing efforts.

Population Locations

Refers to the geographical distribution or positioning of individuals within a given population.

Randomized Block Experiment

An experimental design that involves dividing subjects into blocks based on certain characteristics before randomly assigning treatments within each block to reduce variation.
