The empirical rule in statistics, also known as the 68 95 99 rule, states that for normal distributions, 68% of observed data points will lie inside one standard deviation of the mean, 95% will fall within two standard deviations, and 99.7% will occur within three standard deviations.

The Empirical Rule is a rule telling us about where an observation lies in a normal distribution. The Empirical Rule states that approximately 68% of data will be within one standard deviation of the mean, about 95% will be within two standard deviations of the mean, and about 99.7% will be within three standard deviations of the mean.

2.2.7 - The Empirical Rule | STAT 200 - Statistics Online
The Empirical Rule is a statement about normal distributions. Your textbook uses an abbreviated form of this, known as the 95% Rule, because 95% is the most commonly used interval. The 95% Rule states that approximately 95% of observations fall within two standard deviations of the mean on a normal distribution.
Empirical Rule | Introduction to Statistics | JMP
What is the empirical rule? The empirical rule summarizes the percentage of data from a normal distribution that falls within one, two, or three standard deviations of the mean. What are the requirements to use the empirical rule? Your data should be normally distributed.
