One Method to Check the Population Homogeneity of a Test


Цветков, Димитър (2016) One Method to Check the Population Homogeneity of a Test Proceedings of the Forty Fifth Spring Conference of the Union of Bulgarian Mathematicians, April 6–10, 2016, pp. 187 - 193. ISSN 1313-3330


 In this paper it is considered a method for checking the population homogeneity of a given psychological or didactical test with respect to the way of its accepting from different populations. For this purpose we look for a statistical association between the a priori known populations and posterior estimated clusters on the base of experimental data. The lack of such statistically significant association is considered as an evidence for the absence of a discrimination and therefore as a strong indicator for homogeneity. The posterior clusters are searched by means of the Generalized Partial Credit Model from the Item Response Theory.
