2.4 - Simple Random Sampling and Other Sampling Methods. Probability Sampling: Sample has a known probability of being selected. Non-probability Sampling: Sample does not have known probability of being selected as an inconvenience or voluntary response surveys. It is important to note that, unlike with the strata in stratified sampling, the Stratified sampling is a technique that can help you improve the quality and accuracy of your quantitative research. It involves dividing your population into subgroups or strata based on relevant A stratified sampling is a method in which the total population is divided into homogeneous subpopulation called strata based on specific characteristics [10], of which in this study, the Stratified Sampling. A method of probability sampling (where all members of the population have an equal chance of being included) Population is divided into 'strata' (sub populations) and random samples are drawn from each. This increases representativeness as a proportion of each population is represented. Stratfied Sampling. Heatherton 1997. Stratified sampling is a method of obtaining a representative sample from a population that researchers have divided into relatively similar subpopulations (strata). It produces more precise estimates of each group’s characteristics than simple random sampling. Learn how to use stratified sampling, its advantages and disadvantages, and see an example of stratified sampling in a research study. Proportionate stratified sample is a version of a sampling method call stratified sample. If certain characteristics of population influence phenomenon that is being explored then these characteristics can be used for stratification purposes. That means that population as well as sample will be divided into subpopulation / subsamples described nk n k is the number of sampled units in stratum k k and ∑nk = n ∑ n k = n. In general, you can calculate stratum-specific sample sizes naively by retaining a constant sampling fraction across all the strata: nk = n N ⋅Nk n k = n N ⋅ N k. This is sampling option is called the proportional option. Errors in the sampling frame may result in the sampling frame excluding some sites that are in the target population or including some sites that are not in the target population; Sampling frames based on different GIS scales (e.g., 1:100000 and 1:24000) may result in different estimates for the target population; Statistical Inference.
