In Empirical rule a normal data set, virtually every piece of data will fall within three standard deviations of the mean, the mean here is the average of all the numbers within the set. The Empirical Rule applies to a normal, bell-shaped curve than is symmetrical about the mean. It states that the first standard deviation covers 68% data, the first and second standard deviation covers 95% data, and all the three deviations of the average in normal distribution cover 99.7% data.
