Representative sample


Definition:

The sample whose structure related to the examined characteristics (variables) is similar to the structure of the statistical population from which it comes. Representativeness of the sample (representative sample) can be obtained using both random (probabilistic) and non-random (non-probabilistic) sampling techniques. It should be noted, however, that a better chance of obtaining a representative sample is given by the use of random selection techniques.
