Measurement is the process of assigning values or numerals to represent the actual properties or characteristics of a variable according to a set of defined rules. Simply put, measurement is the act of assigning numbers to specific entities. The term numeral refers to a symbolic or notational representation expressed in the form of a number, but it does not always imply a quantitative meaning. For example, the number printed on a soccer player’s jersey or the numerical coding in a questionnaire (e.g., ‘0’ for “No” and ‘1’ for “Yes”) are instances of such symbolic numerals.
