In other words, it is the sample size minus one: DF = 3-1; DF = 2 If the sample size is 45, DF value is 44. If the sample is 120, the DF value is 119.How to Find Degrees of Freedom Degrees of Freedom Table Applying Degrees of Freedom History of Degrees of Freedom Lesson ...
The F-test in ANOVA also tests group means. It uses the F-distribution, which is defined by the DF. However, you calculate degrees of freedom in ANOVA differently because you need to find the numerator and denominator DF. For more information, read my post aboutHow F-tests Work in ANOVA...

Degrees of freedom is the number of independent pieces of information used to calculate a statistic.
Approximate expressions for the mean and variance of the MLE of Box''s 2-way ANOVA degrees of freedom factor are given for the case when the usual F test for column effects is appropriate even though there is correlation across columns. A simulation study is performed showing the ...
