    When looking at the ANOVA (based upon F-distribution) output and Effect Analysis table (based upon T-distribution) in a typical Fatorial Design data output, I have noticed exactly the same P-values between these 2 methods for any given factor.

    I understand logically that a big P-value in the effect analysis will imply a big P-value in the ANOVA output since the effect is nealy zero (insignifiant) therefore the population variance for that given factor should be equal to or less than that of the error in the F model.

    What is the statistical relationship between these 2 analysis models, or is there is a function for conversion between the T model and F model? They agree with each other perfectly well.

    Thanks a lot.
