If a sample of 100 is to be taken from a population of 1000 farmers consisting of marginal small and large farmers, which of the following will be the most appropriate sampling method ?

Stratified random sampling is appropriate. Divide the farmers into marginal, small and large farm-size strata, then randomly sample within each stratum so that all groups are represented.
How is stratified sampling carried out?
Which one of the following random sampling techniques become more appropriate for homogeneous population groups?
