Stratified Sampling vs. Cluster Sampling
Stratified sampling is the sort of sampling method that is preferred when the individuals in the population are diverse, and they are manually divided into subgroups called strata for precise and accurate results. Whereas in the cluster sampling technique is ideal when the individuals in the naturally occurring groups known as clusters, does not possess much diversity and can be randomly sampled for efficient and cost-effective results.
What is Stratified Sampling?
Stratified sampling is a kind of sampling technique in which the population is divided into two subgroups or strata. The samples are then extracted randomly from every group created. Stratified sampling is best when the individuals in the population differ from each other as a whole; this is because they are manually divided into subgroups. The population elements are selected individually in a stratified sampling method. By heterogeneity, the samples are taken from between the manually created strata. By homogeneity, the samples are taken from within the artificially created subgroups. The divergence of the groups in the stratified sampling method is usually done by the researcher or group of researchers manually on their own set of anticipated techniques. The divergence of the groups in the stratified sampling method is usually done by the researcher or group of researchers manually on their own set of anticipated techniques. Stratified Sampling is subdivided into proportionate stratified sampling and disproportionate stratified sampling.
What is Cluster Sampling?
Cluster sampling is the kind of sampling technique in which the population is not divided manually into any groups, whereas the samples are randomly picked from the naturally formed groups termed as clusters. Cluster sampling is the most efficient sampling technique and is most suitable when the individuals in the population inside the clusters do not have any diversity in them. In the cluster sampling method unlike stratified sampling, the elements of the population are selected collectively. By heterogeneity, the samples are taken within the naturally developed group or cluster whereas when it comes to homogeneity, the samples in cluster sampling are taken randomly from the different clusters as a whole. Cluster Sampling is subdivided into single-stage cluster sampling, double-stage cluster sampling, and multistage cluster sampling.
