Incomplete sampling
WebSampling variation stems from both random selection of sampling units and incomplete counts of animals within those selected units. The first subcomponent of sampling variation, called among-unit variation, arises from sampling only a portion of available plots. Hence, there are a range of possible values for the many different combinations of ...
