Chi-square distribution calculator computes cumulative probability. Fast, easy, accurate. An online statistical table. Includes sample problems and solutions.
Use this Chi Square calculator to easily test contingency tables of categorical variables for independence or for a goodness-of-fit test. Can be used as a Chi-Square goodness-of-fit calculator, as a Chi-Square test of independence calculator or as a test of homogeneity.
Master the concept of Chi-Square Distribution with our intuitive calculator. Find probability density and cumulative probabilities with ease. Choose from Bisection Method, Cornish-Fisher Expansion.
Chi-Square Calculator. You can use this chi-square calculator as part of a statistical analysis test to determine if there is a significant difference between observed and expected frequencies. To use the calculator, simply input the true and expected values (on separate lines) and click on the "Calculate" button to generate the results.
This graph allows you to investigate the chi squared distribution. First set v (Degrees of freedom). Then either set r to be the critical value obtained from the tables or change r so s (the significance level) is at the desired level. t is the test statistic so you can see if a result is significant or not.
