Stratified random sampling is used with populations that are naturally divided into subsets, and it helps to minimize the sampling error by ensuring that each sub-group is represented proportionally in the sample. It does not necessarily eliminate homogeneous sampling error, and if not done properly, it can introduce sampling bias. Sampling error is still present, but it is allocated proportionally across the sub-groups.
