Answer 2

Answer:

The two types of sampling are random sampling and nonrandom sampling. Nonrandom sampling uses some criteria for choosing the sample whereas random sampling does not. The four types of random sampling techniques are simple random sampling, systematic sampling, stratified random sampling and cluster random sampling.

• 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.
