Tabla de distribución F
La distribución F es utilizada, por ejemplo, en la interpretación de un ANOVA. La distribución F resulta del cociente de dos distribuciones chi-cuadrado que se dividen por los respectivos grados de libertad.
Aquí puedes calcular el valor F crítico o el valor p con el número de grados de libertad dados. También puedes leer el valor F crítico para un nivel alfa dado en las tablas siguientes.
Tabla para la distribución F 0.95 (a=0.05)
La siguiente tabla muestra la función de distribución inversa de la distribución F para (1-a) = 0.95. En los ejes se encuentran los grados de libertad del numerador y del denominador.
