Abstract:

In this paper I want to discuss three methods of industrial sampling which can be used in some of the situations in which difficulties can arise. The conclusion I should like to draw from these examples of alternative sampling methods for industrial research is that the classical approach is not necessarily the only, or the best, way of solving a particular problem. In such cases it is very often possible to devise a different approach which overcome the need for a relevant sampling frame or whatever other component of the classical approach is not available.
