Universe and Sample: A Debate about a Particular Relationship

Authors

Keywords:

scientific problem, objet population, accessible population, sample.

Abstract

Introduction: When planning a research study, the definition of the universe and the sample to be studied is a crucial aspect, not free of difficulties and often approached incorrectly.

Objective: To identify the differences between the concepts of universe and sample.

Development: This article deals with these concepts and provides some examples. The universe or population is determined by the set of people generalized upon the base of the research results and the sample is the part of the studied population.

Conclusions: It is concluded that, without a clear and precise delimitation of the population and the sample, there is a risk of carrying out a biased study with validity problems. It is not possible to see only these two aspects in isolation in the process of scientific research, since it is also necessary to delve into questions of representativeness and the role of statistics in the selection of the sample.
