Una de las principales herramientas son las cartas de control. Hawkins plantea un procedimiento para monitorear la variabilidad del proceso mediante cartas de control CUSUM. En este artículo se presenta su aplicación en la medida de variabilidad de los valores de pH en el uso de fungicidas; así, como los resultados sobre su desempeño en comparación con la carta de control de Shewhart, la cual no es tan efectiva para detectar corrimientos pequeños.]]></p></abstract>
