Empirical Rule Calculator
Conquer Statistical Data with Our Free Empirical Rule Calculator!
Understanding statistical data can be daunting. Whether you’re a student tackling statistics for the first time or a professional analyzing data, the Empirical Rule is an indispensable tool in your statistical toolkit. That’s why we’ve crafted our Empirical Rule Calculator to help you quickly and easily determine the spread of your data set.
The empirical rule (also called the “three-sigma rule” or the “68-95-99.7 rule”) is a statistical rule that states that, for normally distributed data, almost all the data points will fall within three standard deviations on either side of the mean.
More specifically, you’ll find:
- 68% of data within 1 standard deviation;
- 95% of data within 2 standard deviations ; and
- 99.7% of data within 3 standard deviations.
Let’s explain the concepts used in this definition:
Standard deviation is a measure of spread; it tells how much the data varies from the average, i.e., how diverse the dataset is. The smaller value, the more narrow the range of data is. Our standard deviation calculator expands on this description.
Normal distribution is a distribution that is symmetric about the mean, with data near the mean being more frequent in occurrence than data far from the mean. In graphical form, normal distributions appear as a bell-shaped curve, as you can see below:
What is the Empirical Rule?
The Empirical Rule, also known as the 68-95-99.7 rule, is a statistical theory stating that for a normal distribution:
- About 68% of data falls within one standard deviation from the mean.
- Approximately 95% falls within two standard deviations.
- Nearly all (99.7%) falls within three standard deviations.
This rule is incredibly useful for approximating the spread of data whenever you’re working with a normal distribution, or “bell curve.”
How To Use Our Calculator
Our Empirical Rule Calculator simplifies your data analysis. Just plug in your mean (average) and standard deviation to immediately understand the range that encloses about 68%, 95%, or 99.7% of your dataset. With a user-friendly interface, our calculator lets anyone make sense of data distribution in a matter of seconds.
