This method is also known as multi stage sampling .Under this method random selection is made of the ultimate or final units from a given stratum. The sampling process is carried out in several stages. At first stage samples are selected by some suitable method. Then the second sample out of the first be chosen again by some suitable method. Further stages may be added as per the requirements.

Merits:
