QUÉ SIGNIFICA FALSE NEGATIVE EN INGLÉS
Errores de tipo I y de tipo II
En las estadísticas, una hipótesis nula es una afirmación de que lo que se estudia no produce ningún efecto o no hace ninguna diferencia. Un ejemplo de una hipótesis nula es la afirmación "Esta dieta no tiene ningún efecto sobre el peso de las personas". Por lo general, un experimentador enmarca una hipótesis nula con la intención de rechazarla: es decir, la intención de ejecutar un experimento que produce datos que demuestran que la cosa bajo estudio hace una diferencia. Un error de tipo I es el rechazo incorrecto de una hipótesis nula verdadera. Con respecto a la hipótesis no nula, representa un falso positivo. Por lo general, un error de tipo I lleva a concluir que existe un supuesto efecto o relación cuando en realidad no lo hace. Ejemplos de errores de tipo I incluyen una prueba que muestra que un paciente tiene una enfermedad cuando de hecho el paciente no tiene la enfermedad, una alarma de incendio que apaga indicando un incendio cuando de hecho no hay fuego o un experimento que indica que un tratamiento médico Debe curar una enfermedad cuando en realidad no lo hace. Un error de tipo II es la falta de rechazo de una falsa hipótesis nula. Con respecto a la hipótesis no nula, representa un falso negativo.
