The methods of selecting a representative sample from least to most effective are:
Least effective:
- Convenience sampling
- Snowball sampling
- Purposive sampling
Most effective:
- Stratified sampling
- Cluster sampling
Why are these effective?
Convenience sampling involves selecting participants who are easily accessible to the researcher, such as classmates or friends. This method is not effective because it is likely to introduce bias into the sample.
Cluster sampling involves dividing the population into clusters, or groups, and then randomly selecting clusters to participate in the study. This method is more effective than the previous methods because it is more efficient and can be used when it is difficult to sample individuals directly.
