A sampling plan is a detailed outline of which measurements will be taken at what times, on which material, in what manner, and by whom. A statistical sampling plan follows the laws of probability, allowing you to make valid inferences about a population from the statistics of the samples taken from it. It also lets you determine in advance the magnitude of the sampling errors.
