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). There are 4 levels of measurement:
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.
Learn the foundations of data analysis, exploring the four fundamental levels of measurement: nominal, ordinal, interval, and ratio scales.
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.
Understanding levels of measurement is pivotal in interpreting and analyzing data accurately. These levels dictate the statistical operations applicable to the data, influencing the choice of analytical methods and the depth of insights extracted from the information.
