An F test is equal to the square of the T test. The test statistic of the F-test has the same PDF as that of the F-distribution. Look at the F value in the F table. There is a different F-distribution for each study design. The mean is approximately 1. F Distribution Tables.

I will describe how to calculate degrees of freedom in an F-test ANOVA without much statistical terminology.

The F-test statistic is the ratio after scaling by the degrees of freedom. In simple terms these are the date used in a calculation. An F-test with 12 degrees of freedom in the numerator and 6 degrees of freedom in the denominator produced a test statistic whose value was 342_ The null and alternate hypotheses were Ho. Graphing the F-test for Our One-Way ANOVA Example For one-way ANOVA the degrees of freedom in the numerator and the denominator define the F-distribution for a design. In the above figure the df numerator or Df1 is equal to 2 and df denominator or Df2 is equal to 57. Lets start with a simple explanation of degrees of freedom.
