STRATIFIED This is a feature of an EXPERIMENTAL DESIGN whereby a scheme of observations is repeated entirely using further sets (strata) of experimental units, with each such further set distinguished by a level of a categorical variable which is distinct from any categorical variables used to define the EXPERIMNATL DESIGN within a single set (stratum). The data from the various strata are regarded as distinct. This situation occurs when attempting to make inferences based upon the results of several similar independent experiments.
