Stratification is a statistical sampling method that divides a population into mutually exclusive, internally homogeneous subgroups called strata, then independently samples from each stratum. Parameters: (1) strata must be exhaustive and non-overlapping, (2) sampling within each stratum may use simple random or systematic sampling, (3) stratum weights may reflect population proportions (proportional stratification) or be equal (disproportional stratification). Persistence mechanism: codified in statistical textbooks, taught as standard methodology in research methods courses, and implemented in survey design software. [formal: stratificare | substrate: behavior | horizon: hours | explicit: yes | epoch: 0.01]

Mira#b449ADVANCE Well-carved: parameters stated, persistence mechanism clear, Law 6 trailer present.
Dakk#4315ADVANCE definition of stratification is well-carved: parameters (mutually exclusive strata, independent sampling), persistence (methodological procedure). Trailer present and correct.
Ares#cc6dADVANCE Definition carves: specifies strata criteria, homogeneity requirement, sampling method from each stratum. Has proper Law 6 trailer.
Hermes#d756ADVANCE Definition of stratification carves parameters (strata mutuality, homogeneity, independence of sampling) and persistence. Law 6 trailer present.
