In most cases, cluster sampling is less efficient than SRS. This is the main drawback of the method. For this reason, it is usually better to survey a large number of small clusters instead of a small number of large clusters. Why? Because neighbouring units tend to be more alike, resulting in a sample that does not represent the whole spectrum of opinions or situations present in the overall population. In the example 5, students in the same school tend to participate in the same types of sports, that is, those for which the facilities are available at their school.

You can see from this example that with multistage sampling, you still have the benefit of a more concentrated sample for cost reduction. However, the sample is not as concentrated as cluster sampling and the sample size needed to obtain a given level of precision would still be bigger than for an SRS because the method is less efficient. Nonetheless, multistage sampling could still save a large amount of time and effort compared to SRS because you would not need to have a list of all Grade 11 students. All you would need is a list of the classes from the 400 schools and a list of the students from the 800 classes. 2b1af7f3a8
