The "probability method" involves the use of random sampling techniques, and multistage cluster sampling is a common type of random sampling that is used to increase the accuracy of survey results. Unitary cluster sampling and quota sampling are other types of sampling methods, but they are less commonly used in the probability method. Inferential sampling may refer to the process of making inferences about a population based on a sample, but it is not a specific type of sampling method.
