3. Sampling Distribution

What Is a Sampling Distribution?

A sampling distribution is a probability distribution of a statistic obtained from a larger number of samples drawn from a specific population. The sampling distribution of a given population is the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population.

In statistics, a population is the entire pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hospital visits, or measurements. A population can thus be said to be an aggregate observation of subjects grouped together by a common feature.

  • A sampling distribution is a statistic that is arrived out through repeated sampling from a larger population.
  • It describes a range of possible outcomes that of a statistic, such as the mean or mode of some variable, as it truly exists a population.
  • The majority of data analyzed by researchers are actually drawn from samples, and not populations.
