Research that produces nothing but books will not suffice.
- Kurt Lewin
Self-selection sampling is appropriate when we want to allow units or cases, whether individuals or organisations, to choose to take part in research on their own accord . The key component is that research subjects (or organisations) volunteer to take part in the research rather than being approached by the researcher directly. To understand more about self-selection sampling, how to create a self-selection sample, and the advantages and disadvantages of this non-probability sampling technique, see the article: Self-selection sampling .
