What are the disadvantages of cluster sampling?
Cluster sampling can lead to higher sampling error compared to simple random sampling, as clusters may not be representative.
Can you explain why it might not be representative?
Sure! If clusters are too homogeneous, the sample may miss diversity, leading to biased results.
Are there any specific scenarios where cluster sampling is particularly problematic?
Yes, in cases where clusters are very similar, like schools in a small town, it can skew the data significantly.
What can researchers do to mitigate these disadvantages?
Researchers can use stratified sampling within clusters or ensure a diverse selection of clusters to improve representativeness.
