*Empirical Rule Calculator* is an online statistics and probability tool for data analysis programmed to calculate if the data follows a normal distribution. This calculator also called as 68-95-99.7 rule, or three sigma rule calculator. The Empirical Rule is applied to the bell shaped cure data and can be calculated from the central tendency mean of the given data set

### Definition

The data set along with Bell Shape curve will be implied to Empirical Rule. The range of the data fall from the mean can vary from 1 to 3 standard deviations or fall within ±3 standard deviations. The Empirical Rule for normal distribution or bell shaped curve defines that 68% of the observations roughly expected to fall within 1 standard deviation of the mean, 95% of the observations expected to fall within 2 standard deviations of the mean and 99.73% of the data values can be expected fall within three standard deviation interval of the mean

The collection of tools employs the study of methods and procedures used for gathering, organizing, and analyzing data to understand theory of Probability and Statistics. The set of ideas which is intended to offer the way for making scientific implication from such resulting summarized data. In many applications it is necessary to calculate if the data follows a normal distribution. With this online Empirical Rule Calculator you can effortlessly make your calculations for given data set
