MERINO SOTO, César A.  and  WILLSON, Victor. Comparison of t distribution variables: an application on the difference of groups to construct validity. liber. [online]. 2013, vol.19, n.2, pp.243-249. ISSN 1729-4827.

It is a statistical technique to compare results of the application of statistical tests based on t distributions. This technique is applied using a MS Excel program; an indicator of the magnitude of the effect (Cohen d) is included, which is part of the current recommendations for publication of statistical results. For a demonstration of the technique the information published in three empirical studies was used and Student’s t distribution variables obtained were compared. The results were consistent with the posted information. Finally, the advantages and methodological conditions of the proper application of the technique in the context of the psychometric and not psychometric research in psychology and education is discussed.

Keywords : Student’s t; statistical analysis; construct validity; methodology.
