To examine the type of answer level of adequate answers with the analysis of variances, the proportion of adequate answers of every subject under each condition was logistically transformed. Each correct answer represented one point, so any given subject could have 5/10, that is, 0.50 of adequate answers under a given condition. Hence, every subject had a score and a proportion associated with that score under each condition analyzed. After the logistic transformation, these data were used to make the relevant comparisons with repeated measures tests or ANOVA, for independent samples, as appropriate.
Para poder analizar el tipo de respuesta con análisis de varianzas con porcentajes o proporciones no es posible realizar este tipo de prueba: WOODS; FLETCHER; HUGHES, 1986, se realizó una transformación logística sobre la proporción de respuestas adecuadas de cada sujeto en cada condición: con estos datos se realizaron las comparaciones pertinentes con pruebas de comparación de medias para medidas repetidas o pruebas ANOVA para muestras independientes, según correspondiera.
