In a non-experimental context, as is the case of selective methodology, and related with structural equation models SEMpeople make the basic mistake of believing that the very estimation of an SEM model is a "per se" empowerment for inferring causality.

Corsini Encyclopedia of Psychology. Experimenal research designes. The most important thing is to be clear on the fact that when applying a statistical test a decision to "reject" the null hypothesis, by itself, is not indicative of a significant finding Huck,p. In these situations researchers must provide enough information concerning the instruments, such as the make, model, design specifications, unit of measurement, as well as the description of the procedure whereby the measurements were obtained, in order to allow replication of the measuring process. MM 8 de jun. Discuss the analytical techniques used to minimize these problems, if they were used. Dada la creciente complejidad de las teorías elaboradas en la psicología en general y en la psicología clínica y de la salud en particular, la probabilidad de ocurrencia de tales errores se ha incrementado.

The Journal of Socio-Economics, 33 On many occasions, there appears a misuse of statistical techniques due to the application of models that are not suitable to the type of variables being handled. Martyn Shuttleworth Feb 19, Whenever possible, use the blocking concept to control the effect of known intervening variables. However it is essential to establish control procedures that will ensure a significant degree of isomorphism between theory and data as a result of the representation in the form of models of the reality under study.
