F Statistic / F Value: Definition and How to Run an F-Test

WebThe P-value is determined by comparing F* to an F distribution with 1 numerator degree of freedom and n-2 denominator degrees of freedom. For the student height and grade point average example, the P-value is 0.761 (so we fail to reject \(H_{0}\) and we favor the reduced model), while for the skin cancer mortality example, the P-value is 0.000 ... WebIf you have only one variable in the model, then t-test on a single variable and its p-value will be the same as F-test on an entire model and its p-value. The difference is when you have more than one variable. In this case it is possible to have individual variable's p-values (from t-test) not significant, yet F-test p-values significant.
