Definición Sample
A sample is a selection of people or objects that are representative of a population. Based on those surveyed as a sample we draw conclusions about the population as a whole.
It is a prerequisite for a statistically meaningful result that the sample, e.g. 2,000 Americans who were questioned on the phone will be a representative cross-section of, for example, all adult Americans over 21 years of age.
In order to select a sample, there are several methods – the most popular being random sampling, cluster sampling and quota sampling.
