Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A statistical population refers to the entire set of individuals, items, or data of interest that a researcher wishes to study or describe.

Representative sampling assures that the sample accurately reflects the characteristics of the population from which it is drawn.

The purpose of developing specific experiment designs and survey samples is to ensure that the data collected is reliable and valid.

An experimental study involves manipulating one or more variables and measuring their effect on a dependent variable, allowing researchers to establish cause-and-effect relationships.
