Una medida de asimetría unidimensional para variables cualitativas

Abstract

Esta investigación metodológica tiene como objetivo definir un concepto de asimetría para variables cualitativas, cuantificarlo y mostrar su validez. Se usó un panel de cinco jueces expertos y simulaciones Monte Carlo. Se definió el estadístico diferencia promedio de frecuencia (dpf) entre pares de categorías ordenadas por homogeneidad de frecuencia. El estadístico dpf mostró un comportamiento ajustado a las expectativas con distintas variantes de la distribución binomial. La correlación entre el promedio de las puntuaciones de asimetría de los jueces y dpf fue muy alta. Para obtener normas orientativas de interpretación, se simularon 20,000 muestras de tamaños 20, 40, 100, 200, 500 y 1000 extraídas de una distribución binomial. Se concluye que dpf es válido para medir asimetría en variables cualitativas.
