Developed by psychologist Stanley Smith Stevens, this framework categorizes variables based on the properties they possess. These four scales of measurement determine how you can manipulate numbers and interpret results, acting as the guardrails for your analytical journey.

However, multiplication and division are invalid because the arbitrary zero point distorts the relational meaning. Choosing the wrong scale can lead to misleading averages or inappropriate statistical tests, while using the correct one ensures the integrity of your findings.
Mastering these concepts allows you to move from simply collecting numbers to genuinely understanding the story they tell. For instance, you can calculate the mode—the most frequent category—but calculating a mean is statistically meaningless here.

Non-parametric statistical tests are typically the appropriate choice for this scale. These categories are mutually exclusive and have no inherent order or quantitative value.
