- Simple random sampling. In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
- Systematic sampling.
- Stratified sampling.
- Clustered sampling.
- Convenience sampling.
- Quota sampling.
- Judgement (or Purposive) Sampling.
- Snowball sampling.
