Adaptación de medidas de fiabilidad a cuestionarios de respuestas con datos fuzzy intervalares
J. García-García, M. A. Lubiano, A. M. Castaño, A. L. García-izquierdo
En estudios anteriores (Lubiano et al. 2016) se ha documentado que con el empleo de la escala de valoración fuzzy libre (FRS) se obtienen diferentes conclusiones estadísticas que con la escala tipo Likert. Además, cuando el análisis involucra magnitudes imprecisas, la FRS presenta la ventaja de permitir captar las diferencias individuales y la imprecisión de dichas respuestas.
En este trabajo se ha recurrido al empleo de la escala de valoración fuzzy libre con datos intervalares con el objetivo de agilizar el diseño y recogida de datos en cuestionarios en línea que involucran muchos ítems para medir ciertos aspectos psicosociales.
Para la presentación de resultados se establece el coeficiente de Cronbach con datos intervalares y se analiza la fiabilidad de diferentes medidas psicosociales en el cuestionario, comparando los resultados con los que se habrían obtenido si se redujera la información recabada al punto medio del intervalo (como ‘sucedáneo’ de la escala visual analógica).
Keywords: escalas tipo Likert; escalas fuzzy libre; datos intervalares; coeficiente de Cronbach
