TABLAS PARA EL CÁLCULO DE LA CORRELACIÓN BISERIAL

Estas tablas proporcionan los valores que corresponden a la variable dicotómica que permiten obtener el coeficiente de correlación biserial.
La primera columna p proporciona el valor de la proporción (de 0.99 a 0.01), siendo q=1-p el valor complementario.
La segunda y tercera columna proporcionan el producto pq y su raiz cuadrada. La raiz del producto pq permite obtener el coeficiente de correlación biserial puntual.
La sexta columna proporciona el valor de la ordenada y, en la distribución normal, del punto que divide a la distribución normal en dos partes cuyas áreas respectivas son p y q.
En función del valor de la ordenada y, las columnas cuarta y quinta proporcionan, respectivamente, los valores de pq/y y de p/y que permiten obtener, por dos vías alternativas, el coeficiente de correlación biserial.
