- enhance statistical precision as ensures that no strata/group is missed or not represented.
- samples are proportional so they are accurately representative of the population
- no group is overrepresented or underrepresented
- Allows use of different sampling techniques for different subpopulations.
- get separate means for each strata and draw separate inferences from each of the different strata that may be lost in a more generalized random sample (ie. Simple Random Sampling)
