Nov 21, 2023 · There are four main levels of measurement: nominal, ordinal, interval, and ratio. 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.
