Diseños de respuesta múltiple: aplicación de la teoría de la detección de señales al análisis de la inferencia visual de series de tiempo

Abstract

Visual inspection and type of graphs used. The objective of this research was to see if the evaluation of the effectiveness of a given treatment through visual inspection depends on the type of graphs used. Three subjects were studied with 3000 graphs (1.000 line, 1.000 bar and 1.000 box-plots), each one representing the results of an A-B design. The results indicate that the subjects committed more errors when the data was presented by lines or bars instead of box-plots.
