 '''Statistical sampling''' is the process of finding a representative portion of a large population. In quality control, a percentage of products will be selected at random for testing, and the results ''extrapolated'' to the population. For example, out of 100,000 [[car]]s produced, 30 might be crash-tested. The results will be assumed to hold for the entire population of cars actually sold.
-In [[public opinion]] polls, the sample must be carefully done in order to avoid several kinds of bias.
