### How does the Analysis of Variance (ANOVA) Calculator work?

Performs 1 way analysis of variance or 2 way analysis of variance on a set of data with critical value test and conclusion.
This calculator has 1 input.

### What 4 formulas are used for the Analysis of Variance (ANOVA) Calculator?

1. SSE = SST - SS(Tr)
2. MS(Tr) = SS(Tr)/(k - 1)
3. MSE = SSE/k(n - 1)
4. f = MS(Tr)/MSE

anova
Analysis of variance - statistical models used to analyze the differences among group means
critical value
a point on the distribution of the test statistic under the null hypothesis that defines a set of values that call for rejecting the null hypothesis.
hypothesis
statistical test using a statement of a possible explanation for some conclusions
null hypothesis
in a statistical test, the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
