judgement sample
Definition:
A form of non-probability or purposive sample in which the researcher selects potential RESPONDENTS on the basis that they conform with some basic criterion specified as relevant to the POPULATION to be sampled, e.g. age, ownership of an article, activity etc., judgement samples are selected on the basis of what some expert thinks particular sampling units or elements will contribute to answering the particular research question or problem in hand. For example, in test marketing, a judgement is made as to which cities would constitute the best ones for testing the marketability of a new product. In judgement sampling the degree and direction of the SAMPLING ERROR are unknown and definitive statements are not meaningful.
