Definition 2.1.1

Оглавление

A population is a collection of all elements that possess a characteristic of interest.

Populations can be finite or infinite. A population where all the elements are easily countable may be considered as finite, and a population where all the elements are not easily countable as infinite. For example, a production batch of ball bearings may be considered a finite population, whereas all the ball bearings that may be produced from a certain manufacturing line are considered conceptually as being infinite.
