Disproportionate Stratified Sampling Methodĭisproportionate stratified sampling is a stratified sampling method where the sample population is not proportional to the distribution within the population of interest. Proportionate Stratified Sampling Methodġ.To achieve this, researchers rely on two methods of stratified sampling namely The golden rule of stratified sampling is that every stratum should have distinct characteristics that differentiate it from the others. The whole idea is to preserve the homogeneity within each group, so that no subset is excluded from the eventual sample. When splitting the population into smaller groups, the researcher relies on the naturally-occuring divisors such as geographical location, gender, education level, and age, to mention a few.įor example, when conducting research on the level of education amongst women in a community, one can identify different population groups based on ethnicity, gender, religion, and income level. This method often comes to play when you’re dealing with a large population, and it’s impossible to collect data from every member. Stratified sampling is a selection method where the researcher splits the population of interest into homogeneous subgroups or strata before choosing the research sample. In this article, we’d show you how to do this, also touch on the different types of stratified sampling. To get the most reliable results, you need to map out heterogeneous divisors in your population, so you can have truly diverse strata. ![]() Stratified sampling can help you achieve this. However, when you’re dealing with a larger audience, you need a more effective way to gather relevant and unbiased feedback from your sample. If you’re researching a small population, it might be possible to get representative data from every unit or variable in the target audience.
