a district in the ashanti region town has 102 towns and villages. if you interviewed everyone living in one village, would you be interviewing a population or a sample from the village?
We would be investigating a sample from the village.
A population commonly contains too many individuals to study conveniently, so an investigation is often restricted to one or more samples drawn from it. A well chosen sample will contain most of the information about a particular population parameter but the relation between the sample and the population must be such as to allow true inferences to be made about a population from that sample.
