Resumen

En este texto se presenta una crítica a los métodos utilizados por los artículos científicos convencionales. Esto lleva a tres conclusiones generales sobre el uso convencional de los métodos estadísticos: en primer lugar, los resultados suelen presentarse de una manera innecesariamente confusa; en segundo lugar, el paradigma empleado para probar las hipótesis nulas tiene profundas fallas (por lo general, es preferible la estimación de la magnitud de los efectos y citar los intervalos o los niveles de confianza); y, en tercer lugar, hay varios problemas, independientemente de los conceptos estadísticos particulares empleados, los cuales limitan el valor de cualquier enfoque estadístico. Los dos primeros problemas se pueden remediar fácilmente, mientras que el tercero significa que, en algunos contextos, emplear ciertos enfoques estadísticos puede que no valga la pena. El estudio de caso que se emplea es un artículo sobre administración, pero problemas similares también surgen en otras ciencias sociales.
