in stratified sampling random sampling is applied to each strata
in cluster sampling, first few samples are selected and random sampling is applied to only those selected clusters

in block sampling consecutive set of 10 / 20 / 30.. etc units are selected , so selection is not for one unit but defined number of group of consecutive units

interval sampling eg selecting every 10 item
