Good Morning, Jose,
This is true. While cluster sampling provides the researcher with a methodology which is more economical to conduct, while allowing him or her to allocate his or her resources to those few randomly selected clusters, and, in addition, allowing the same researcher the ability to increase his or her sample size due to shared commonalities with specific clusters, the reality always exists that the population may not be accurately portrayed in these clusters. Why?
There is an inherent tendency to select specific clusters which skew the sample due to those clusters being either over-represented or under-represented. This is due to individuals within those clusters to have similar characteristics. In addition, there also is a higher probability sampling technique with a possibility of high sampling error. This is brought by the limited clusters included in the sample leaving off a significant proportion of the population unsampled.
For these reasons the above statement is true. I hope I have assisted you with this problem, and encourage you to feel free to provide feedback or questions in the comment section below this answer. If you need further assistance, please feel to contact any tutor for that information. Have a great day!
Best!
