                III
Error III. Presentación de resultados.


info@qbsconsultora.es          Telf: 660.136.893 / 661.074.737
Interpretación de parámetros

  La presentación de los datos estadísticos contribuye, en gran
  medida, a la compresión de los resultados y conclusiones del
  trabajo.



  Estos resultados se pueden presentar en lenguaje escrito,
  tabular y gráficamente pero en cualquier caso los contenidos
  deben ser suficientes y claros.

Situación

  Los errores más comunes que hemos encontrado a la hora de
  presentar los datos son aplicar una precisión innecesaria, que
  puede incluso llegar a ser incorrecta, y la omisión de medidas
  que están estrechamente relacionadas, como por ejemplo una
  media y su desviación estándar.

Ejemplo




                          Falta S.D

Qué se debe hacer…

  La afirmación ‘más es mejor’ no siempre funciona, sobre todo a la
  hora de expresar con precisión los resultados. Hay que tener en
  cuenta que si el valor de nuestra significación es < 0,0001, es
  suficiente esta expresión, al igual que si es < 0,001. En la
  mayoría de los casos con una precisión de 2 ó 3 decimales es
  suficiente.

Qué se debe hacer…

 Por otra parte, hay que tener en cuenta, y así lo veremos en un
 error dedicado al tema, que existen parámetros estadísticos que
 no debemos presentar en ‘soledad’, como es el caso de una
 media sin su desviación estándar o de una significación sin el
 estadístico asociado, como pueda ser el valor F, t-Student, entre
 otros.
