Methods for assessing the reliability of measurement scales were investigated. Reliability, which is defined as the ratio of the true variance to the total variance, is an important property of measurement.

Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal , ordinal , interval , and ratio . Level of measurement refers to the particular way that a variable is measured within scientific research, and scale of measurement refers to the particular tool that a researcher uses to sort the data in an organized way, depending on the level of measurement that they have selected.

Scales of Variable Measurement Scales of Variable Measurement Variables are measurement using an instrument, device, or computer.

Example: The Celsius scale: The difference between 40 C and 50 C is the same as that between 20 C and 30 C (meaningful difference = equidistant). Besides, 50 C is hotter than 40 C (order). However, 20 C is not half as hot as 40 C and vice versa (doubling is not meaningful). Measurement scales are used to categorize and/or quantify variables.
