To calculate the p-value for Supplement from the simple model above:
Go to Calc > Probabilities Distributions > F… “Click on Cumulative probability”.
For “numerator degrees of freedom:”, enter the degrees of freedom for Supplement, which is 2.
For “denominator degrees of freedom:”, enter the degrees of freedom for the error term, which is 6
Click on “Input constant:”. In the box to the right, enter the numerical value of F for the factor, which is 9.25. Click OK.
The output will look like
