Monitoring and evaluation guidance - Chapter 3: sampling


This chapter explains the basics of sampling including why we sample, how to decide your sample size and how to make sure the sample is representative. It also helps you to be clear about your target area, and how you can select and profile your target population.

Sampling is not a particularly complex task but your ability to make valid statements about your results depends on a good understanding of sampling. In particular, you will want to be able to state what the results obtained from your sample say about the wider population from which the sample was drawn. The intention of this chapter is to help you to do this.
