Definition of

sampling

  • 1. Marketing

    providing free samples a sales promotion technique in which customers and prospects are offered a free sample of a product

  • 2. Statistics

    selecting representative subgroup from population under investigation the selection of a small proportion of a set of items being studied, from which valid inferences about the whole set or population can be made. Sampling makes it possible to obtain valid research results when it is impracticable to survey the whole population. The size of the sample needed for valid results depends on a number of factors, including the uniformity of the population being studied and the level of accuracy required. The technique is based on the laws of probability, and a number of different sampling methods can be used, including random sampling and nonrandom sampling.
