The empirical rule, also known as the 68-95-99.7 rule, is a handy way to analyze statistical data. It only work for a normal distribution (bell curve), however, and can only produce estimates. You’ll need to know the mean and standard deviation of your data.

The empirical rule, also known as the three-sigma rule or the 68-95-99.7 rule, provides a quick estimate of the spread of data in a normal distribution given the mean and standard deviation. Specifically, the empirical rule states that for a normal distribution: 68% of the data will fall within one standard deviation of the mean. The empirical rule refers to a regular distribution. Pretty nearly, all information in a normal distribution comes inside three standard deviations of the mean.

An example of the application of the Empirical Rule to a problem that asks for the area between two equal boundaries. 1. The heights of tomato plants in a certain garden are normally distributed with a mean of 40.5 inches and a standard deviation of 1.9 inches.

Look at a table of z-scores (which comes later, for folks who aren't up to that yet). P (-1 < X < 1) = 0.6826. P (-2 < X < 2) = 0.9544. P (-3 < X < 3) = 0.9973.

The empirical rule is just a rough estimate of that.

Empirical Rule is a statistical concept that helps portray the probability of observations and is very useful when finding an approximation of a huge population.
