Research Design Guidance: Sampling Impact Initiatives (2020)
Sampling is the process of selecting units (i.e. a sample) within the wider population of interest, so as to be able to make inferences and estimate characteristics and behaviour of the wider population. Sampling is different from census which is when every single unit within the wider population of interest is covered for the research. A complete census is often not practical or possible in a humanitarian or development setting. This document provides practical guidance on how IMPACT country teams should go about this crucial step of sampling during the research design stage of any research cycle. Specifically, it will cover:
Ø Overview of probability and non-probability sampling;
Ø Types and applicability of different probability and non-probability sampling strategies;
Ø How to operationalise the selected sampling strategy;
Ø Frequently asked Questions (FAQs) related to sampling, including methodological issues encountered during data collection.
