ANOVA F-Test Calculator

Compute the F-statistic for a one-way ANOVA test by entering sums of squares and degrees of freedom. Use it when comparing means across three or more groups to test whether at least one differs significantly.

Sum of Squares Between Groups (SSB)

Sum of Squares Within Groups (SSW)

Degrees of Freedom Between (dfB)

Degrees of Freedom Within (dfW)

Chi-Square Test Calculator

Compute the chi-square test statistic contribution for one observed-vs-expected category pair using χ² = (observed − expected)² / expected. Sum these contributions across all categories to get the total χ² statistic for goodness-of-fit or independence tests.
