In order to draw accurate conclusions about a population while studying only part of it, it is necessary to have a representative sample. A representative sample is a subset of a population that accurately reflects the characteristics of the whole population. This means that every member of the population has an equal chance of being selected for the sample and that the sample has the same distribution of important characteristics as the population.
