random sampling


statistical technique for sampling individuals at random an unbiased sampling technique in which every member of a population has an equal chance of being included in the sample. Based on probability theory, random sampling is the process of selecting and canvassing a representative group of individuals from a specific population in order to identify the attributes or attitudes of the population as a whole. Related sampling techniques include: stratified sampling, in which the population is divided into classes, and random samples are taken from each class; cluster sampling, in which a unit of the sample is a group such as a household; and systematic sampling, which refers to samples chosen by any system other than random selection.
