This method entails the random selection of a whole subclass, as opposed to the sampling of members from each subclass. Each of the subclasses should portray comparable characteristics to the entire selected sample. Cluster samplingĬluster sampling, which, similar to the stratified sampling method, includes dividing a population into subclasses. The stratified sampling method is useful, as it allows the researcher to make more reliable and informed conclusions by confirming that each respective subclass has been adequately represented in the selected sample. Stratified sampling, which includes the partitioning of a population into subclasses with notable distinctions and variances. The systematic sampling method is comparable to the simple random sampling method however, it is less complicated to conduct. The selection often follows a predetermined interval (k). Systematic sampling is the selection of specific individuals or members from an entire population. The simple random sampling method is one of the most convenient and simple sample selection techniques. It provides each individual or member of a population with an equal and fair probability of being chosen. Simple random sampling is the randomized selection of a small segment of individuals or members from a whole population. There are four primary, random (probability) sampling methods. There are four primary, random (probability) sampling methods – simple random sampling, systematic sampling, stratified sampling, and cluster sampling. It is essential to keep in mind that samples do not always produce an accurate representation of a population in its entirety hence, any variations are referred to as sampling errors.Random sampling, also known as probability sampling, is a sampling method that allows for the randomization of sample selection.
