What are the limitations of simple random sampling?
Simple random sampling can lead to issues like non-representative samples, especially in heterogeneous populations.
Can you explain how it might lead to non-representative samples?
Sure! If certain groups are underrepresented in the population, they may not be included in the sample, skewing results.
Are there any specific scenarios where this is particularly problematic?
Yes, in studies involving rare diseases or specific demographics, simple random sampling might miss crucial data.
What are some alternatives to simple random sampling?
Alternatives include stratified sampling, cluster sampling, and systematic sampling, which can provide more representative samples.
