  "definition": "1. Measurements collected on some grouping of individuals, e.g., litters in reproductive and developmental studies.\n\n2. Measurements collected on individuals that occur in groupings or clusters, e.g., littermates in reproductive and developmental studies. Circumstances common to members of the group (maternal environment, inherited traits, conditions of rearing) may exert a common influence upon outcomes of experimental treatments, leading to greater similarity in response between the members of a group. Statistical models of response that account for outcomes in such experiments will adjust for both the within-group and between-group variability of responses.",
