Cluster sampling allows for the use of conventional formulas for computing statistics, but these formulas may need adjustments to account for the design effect due to clustering. This method does not necessarily require including participants from every sampling unit, nor is it inherently more expensive or rejects randomization. The main disadvantage is that it can introduce more sampling error compared to simple random sampling because individuals within each cluster are more similar to each other than to the overall population.
