Note: The Empirical Rule implies that a data set that is normally distributed has a width of approximately 6 standard deviations (Widtℎ ≈ 6 𝜎 ). Tapering Ends.

2000 freshmen at State University took a biology test. The scores were distributed normally with a mean of 70 and a standard deviation of 5.

The empirical rule (68%, 95%, 99.7%) for mound shaped data applies to variables with normal distributions. For example, approximately 95% of the measurements.

If a distribution of data is approximately symmetric and bell-shaped, about 95% of the data should fall within two standard deviations of the mean. 9.
