Step	Instructions	Example
1. Find the mean and standard deviation of your data set.	The mean is the average of all the values in your data set. The standard deviation is a measure of how spread out the values are.	The mean of a data set of 10 numbers is 50, and the standard deviation is 10.
2. Find the z-score of your value.	The z-score is a measure of how far your value is from the mean, in terms of standard deviations.	The z-score of a value of 60 in the data set above is 1, because (60 – 50) / 10 = 1.
3. Use the z-score to find the probability that a value will be within a certain range.	The 68-95-99.7 rule states that: 68% of values will be within one standard deviation of the mean. 95% of values will be within two standard deviations of the mean. 99.7% of values will be within three standard deviations of the mean.	The probability that a value will be between 40 and 60 in the data set above is 68%, because (60 – 50) / 10 = 1 and (40 – 50) / 10 = -1.

The 68-95-99.7 rule, also known as the empirical rule or the normal distribution, is a statistical principle that describes the distribution of data around a mean value. The rule states that approximately 68% of the data will fall within one standard deviation of the mean, 95% of the data will fall within two standard deviations of the mean, and 99.7% of the data will fall within three standard deviations of the mean.

The 68-95-99.7 rule can be used to estimate the probability of an event occurring. For example, if you know that the average height of women in a population is 5 feet 4 inches, and the standard deviation is 2 inches, you can use the 68-95-99.7 rule to estimate that 68% of women in the population will be between 5 feet 2 inches and 5 feet 6 inches tall, 95% of women will be between 5 feet 0 inches and 5 feet 8 inches tall, and 99.7% of women will be between 4 feet 10 inches and 5 feet 10 inches tall.

The 68-95-99.7 rule can also be used to calculate the probability of an event occurring within a certain range. For example, if you know that the average score on a test is 70, and the standard deviation is 10, you can use the 68-95-99.7 rule to calculate that there is a 68% probability that a student will score between 60 and 80, a 95% probability that a student will score between 50 and 90, and a 99.7% probability that a student will score between 40 and 100.

The 68-95-99.7 rule is a powerful tool that can be used to make predictions about the probability of an event occurring. However, it is important to remember that the rule is only an approximation, and the actual probability of an event occurring may vary from the predicted probability.
