Empircal Rule

The empirical rule which is also known as the three sigma rule or the 68 95 99 7 rule represents a high level guide that can be used to estimate the proportion of a normal distribution that can be found within 1 2 or 3 standard deviations of the mean.
Empircal rule. The empirical rule can be broken down into three parts. It is also known as a three sigma rule and 68 95 99 7 rule. Practice applying the 68 95 99 7 empirical rule. The empirical rule is a statistical rule stating that for a normal distribution almost all data will fall within three standard deviations of the mean.

Empirical rule calculator is a statistical tool to compute the normal distribution of given data. It only work for a normal distribution bell curve however and can only produce estimates.
More precisely 68 27 95 45 and 99 73 of the values lie within one two and three standard deviations of the mean respectively. The mean is the average of all of the numbers within the set. In mathematics the empirical rule says that in a normal data set virtually every piece of data will fall within three standard deviations standard deviation from a statistics standpoint the standard deviation of a data set is a measure of the magnitude of deviations between values of the observations contained of the mean. The empirical rule also known as the 68 95 99 7 rule is a handy way to analyze statistical data.
