Binomial distribution, probability density function, cumulative distribution function, mean and variance
This calculator calculates probability density function, cumulative distribution function, mean and variance of a binomial distribution for given n and p
Pearson correlation coefficient
The Pearson correlation coefficient calculator is a tool that allows users to input sets of paired random variables and calculate the correlation between them.
Histogram Builder
The Histogram Builder calculator allows users to input a set of numbers and generate a histogram, either by using the Sturgess, Scott or Freedman-Diaconis formula, or manually setting the number of groups.
The Symbol Frequency Table Calculator
The Symbol Frequency Table Calculator is a tool that takes in a text message and produces a table of the frequencies of each symbol (i.e., character) that appears in the message. The calculator can be customized to ignore spaces and/or case, allowing for a more accurate analysis of the message's symbol frequencies.
