Non-random sampling

The purpose of this method is to make an explicit choice based on your own judgement about exactly whom to include in your sample. When random sampling is not possible, then you can choose this sampling method for studying how primary stakeholders are affected by a project intervention. You might, alternatively, want a very specific perspective so you purposefully seek certain people or groups. As with random sampling, from an M&E perspective, the sample is needed to guide the use of information-collection methods.
