Enter up-to-14 pairs of Observed & Expected frequencies, and then click the Calculate button. Blank boxes are not included in the calculations.

In entering your data to move from cell to cell in the data-matrix use the Tab key not arrow or enter keys.

The Degree of Freedom is often the number of occupied paired-cells minus one.

H0: The observed frequency table fits the claimed distribution.

Observed - Oi
Expected - Ei
Degree of Freedom

Prueba de Bondad de Ajuste para Variables Aleatorias Discretas
Introduzca hasta 14 pares de frecuencias observadas (Observed) y esperadas (Expected), luego presione el botón Calculate (Calcular). Las filas y/ o columnas vacías no serán incluidas en los cálculos.
Mientras entre sus datos en la matriz, muévase de celda a celda usando la tecla Tab, no use la flecha o la tecla de entrada.
El Degree of Freedom (Grado de Libertad) normalmente es el número de celdas ocupadas medos uno.
Ho: La frecuencia observada que ajusta la distribución propuesta.
Los resultados que usted obtendrá de esta matriz son:
Chisquare = Chi- cuadrado
P- value = Valor P
Conclusion = Conclusión
