How are the results of the cognitive ability books EA and EN, interpreted?
The responses to Cognitive Ability questionnaires can be interpreted according to a scale of 0 to 100, where individuals who had no correct responses are coded with a “0”, while individuals with full success are coded with a “100”. However, for a more detail description on the subject of individual cognitive levels, you can consult the following literature: Raven J.C., Court J.H and J. Raven (1993), Test de Matrices Progresivas. Escalas Coloreada, General y Avanzada, Paidos Iberica Eds. ISBN: 9501260607.
