Glossary - sampling technique

Indexsampling technique

This is the means by which we select a sample from a sample frame and takes two main forms: probabilistic sampling An approach whereby we aim to obtain a sample that is a representative cross-section of the sampling frame. Major forms include random, systematic, stratified and cluster sampling. non-probabilistic sampling Such forms may be employed where it is impractical or unnecessary to have a representative sample. Forms include purposive, snowball, selfselection and convenience sampling. These are discussed in more detail in (Oates 2006).
