Sampling error is the difference between the value of a sample statistic and the corresponding parameter in the population from which the sample was drawn. The idea behind sampling error is that a chosen sample typically does not provide a perfectly accurate representation of the population from which it was selected. The discrepancy, or “error,” between a measurement computed for a sample (which is known as a statistic) and the actual value in the population (which is known as a parameter) is referred to as sampling error. In this context, the term error is nonpejorative and refers to the inherent variability found in different samples taken from the same population.
