Probability
Chi-Square Goodness of Fit Calculator
Tests whether your observed frequency counts match a theoretically expected distribution. Use it to check if a die is fair, verify that survey responses follow a predicted pattern, or validate a statistical model.

Probability
Hypergeometric Distribution Calculator
Calculates exact probabilities when drawing items from a finite population without replacement. Use it in quality control, card games, or any scenario where sampling changes remaining proportions.
