State any three merits of stratified random sampling.

Answer»

•  A random stratified sample is superior to a simple random sample because it ensures representation of all groups and thus it is more representative of the population that is being sampled. 

•  A stratified random sample can be kept small in size without losing its accuracy. 

•  It is easy to administer if the population under study is sub-divided.
