Statistics Calculators


This online Empirical Rule Calculator finds the ranges of 1 standard deviation, 2 standard deviations, and 3 standard deviations from the mean, which contain 68%, 95%, and 99.7% of normally distributed data, respectively.


This online calculator computes the exponential regression line parameters as well as the number of input points and the correlation coefficient. The results are presented in the graph.


Calculates the number of times a data value occurs in a given data set. The frequencies are presented in the form of absolute, relative or cumulative frequency.


Computes the hypergeometric probability, given the population size, the number of successes in the population, the sample size and the number of successes in the sample, as well as relevant cumulative probabilities.


The linear regression calculator finds the line of best fit for a given data set in case it is assumed to be a straight line on a two-dimensional plane.


This statistics calculator is intended for calculation of the mean, median and mode values in a given set of data.


This statistical calculator finds the midrange value for a given data set and the minimum and maximum values in that data set.


Computes the probability of the exact outcome of a multinomial experiment (multinomial probability), given the number of possible outcomes and respective number of pairs: probability of a particular outcome and frequency of this outcome (number of its occurrences).


Performs fast number sorting in ascending or descending order. The results can be delimited by comma or space.


This odds to probability calculator converts the odds for an event into the probability of the event. And conversely it can convert the probability of an event into the odds for the event, so it’s also a probability to odds calculator.
