High Wycombe: Griffin, 1984. — 106 p.
This book is a revision of the earlier volume entitled Basic ideas of Scientific Sampling, and includes a new section on Quota Sampling and Non-Response in Sampling. It sets out to explain, in the least technical manner possible, the ideas underlying the theory of sampling, which is the basis of the rather elaborate survey procedures now commonly used by government departments, in industry and in commerce. Sampling theory is necessarily mathematical, and it is difficult to pay enough attention to basic ideas in the course of a technical exposition without lengthening it unduly; in any case, such a mixture usually has the disadvantage of making the ideas inaccessible to the non-mathematically inclined. In this short book, the principles of sampling are illustratively expounded and verified on samples from a small population.
