There are actually four different data measurement scales that are used to categorize different types of data: 1. Nominal. 2. Ordinal. 3. Interval. 4. Ratio. In this post, we define each measurement scale and provide examples of variables that can be used with each scale.
Levels of measurement, also called scales of measurement, tell you how precisely variables are recorded. In scientific research, a variable is anything that can take on different values across your data set (e.g., height or test scores).
Overview: Levels of measurement. Here’s what we’ll be covering in this post. Click to skip directly to that section. What are levels of measurement in statistics? Nominal data; Ordinal data; Interval data; Ratio data; Why does this matter? Recap & visual summary
In this guide, we’ll explain exactly what is meant by levels (also known as types or scales) of measurement within the realm of data and statistics—and why it matters. We’ll then introduce you to the four types of measurements, providing a few examples of each.
The nominal, ordinal, interval, and ratio scales are levels of measurement in statistics. These scales are broad classifications describing the type of information recorded within the values of your variables. Variables take on different values in your data set. For example, you can measure height, gender, and class ranking.
Within science, there are four commonly used levels and scales of measurement: nominal, ordinal, interval, and ratio. These were developed by psychologist Stanley Smith Stevens, who wrote about them in a 1946 article in Science, titled " On the Theory of Scales of Measurement."
Learn the foundations of data analysis, exploring the four fundamental levels of measurement: nominal, ordinal, interval, and ratio scales.

Levels of measurement categorize data according to their characteristics and the mathematical operations permissible for analysis. The hierarchy encompasses four primary types: nominal, ordinal, interval, and ratio. Each level holds distinct attributes defining the nature and scope of quantitative assessment.
There are four levels of measurement: nominal, ordinal, interval, and ratio. Knowing about a different level of measurement helps in selecting appropriate statistical tests for your data. It will be essential when presenting or analyzing the results of your statistical investigation.
