🎲 Chi-Square Test
Goodness of fit test for observed vs expected
About this calculator
The chi-square goodness of fit test compares counts you observed against counts you expected, category by category. It returns the chi-square statistic and degrees of freedom, which you compare against a chi-square table or convert with the P-Value Calculator.
Tip: this test needs counts, not percentages, and every expected count should ideally be 5 or more.
