tamaño del efecto, intervalos de confianza, software estadístico

Resumen

En la actualidad se observa un uso más intenso de indicadores de tamaño del efecto para informar resultados de investigaciones. Se discute primero la importancia de comunicar de manera comparable los resultados de investigación en Ciencias Sociales, para luego ejemplificar diferentes casos de aplicación de medidas de tamaño del efecto. A continuación se ilustra la razón por la que la estimación del tamaño del efecto no es una extensión intuitiva de los intervalos de confianza usuales y se muestra el procedimiento para hacerla. Finalmente, se usa el paquete MBESS en lenguaje R a través de INFOSTAT® para realizar las estimaciones de manera sencilla.
