Calculates the probability of an event “A” conditional on another event “B”, given the prior probabilities of “A” and “B”, and the probability of “B” conditional on “A”. Enter the values of any three parameters into this Bayesian calculator and find the missing parameter.
This online calculator is designed to calculate the first digit frequencies in numbers comprising a given data set and test the hypothesis for their compliance with Benford’s law.
Calculates the value of the binomial coefficient C(n,k) given values of the parameters “n” and “k”, that must be non-negative integers in the range of 0 ≤ k ≤ n < 1030.
Calculates the probability of an exact binomial outcome (the binomial probability), given the number of trials, the number of successes, and the probability of the successful outcome of a single trial. You can also compute cumulative binomial probabilities for no more or for no less than a given number of successes.
Performs calculation of the probability that two or more persons in given group of people will have the same birthday.
This online Chebyshev’s Theorem Calculator estimates the maximal probability Pr that a random variable X is outside of the range of k (k > 1) standard deviations σ of the mean μ.
Calculates the value of chi-square statistic for a given set of observed and expected frequencies, and also the degrees of freedom and the corresponding P-value (right tail or left tail).
This online correlation coefficient calculator (or the Pearson correlation coefficient calculator) can help in determining the correlation between two statistical variables.
This statistics calculator computes the mean values and covariance of two given sets of data points. It calculates also the number of input values (dataset size).
