[edit] Stratified Sampling
A form of probabilistic sampling in which the region or site is divided into natural zones or strata such as cultivated land and forest; units are then chosen wither randomly or in a systematic way so as to give each zone a number of squares proportional to its area, thus overcoming the unherent bias in simple random sampling.
