This page will calculate the value of chi-square for a one- dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H. To enter an observed cell frequency, click the cursor into...

This page, created by Professor Ivo Dinov of the University of California Berkeley, provides a table of chi-square distribution probabilities with degrees of freedom 1-45. This page was created as a reference tool for...

This site, created by the Department of Statistics at Yale University, gives an explanation, a definition and an example of chi-square goodness of fit test. Topics include chi-square test statistics, tests for discrete...

This page, created by Richard Lowry of Vassar College, generates a graph of the chi-square distribution and displays the associated probabilities. Users enter the degrees of freedom (between 1 and 20, inclusive) upon...

This tutorial, created by Thomas W. MacFarland of Nova Southeastern University, explains the theory and use of the Chi-square tests for "Goodness of Fit" and demonstrates it with an example on mastery test scores. Data...
