Abstract

So as to decrease cost as well as to focus the field tasks around chosen focuses and simultaneously get exact evaluations, sampling is at times completed in stages. The system of first choosing huge measured units and after that picking a predetermined number of sub-units from the chose enormous units is known as sub-sampling. The enormous units are called 'first stage units' and the sub-units the 'second stage units'. The method can be effectively summed up to three phase or multistage tests. For instance, the sampling of a timberland region might be done in three phases, right off the bat by choosing an example of compartments as first stage units, also, by picking an example of land areas in each chose compartment and ultimately, by taking various example plots of a predetermined size and shape in each chose geographical segment.
