The Empirical Rule, also known as the 68-95-99.7 Rule, is a fundamental concept in statistics that helps us understand how data is spread around the mean in a normal distribution. Whether you're a student, a data enthusiast, or just curious about statistics, this rule is a powerful tool to make sense of data. In this post, we’ll break down the Empirical Rule and show you how to calculate it step by step. What is the Empirical Rule? The Empirical Rule states that for a normal distribution: 68% of the data falls within 1 standard deviation of the mean. 95% of the data falls within 2 standard deviations of the mean. 99.7% of the data falls within 3 standard deviations of the mean. This rule applies only to data that is normally distribu...
