Abstract: In this paper we investigate the behavior of the conditional probability Prob (U gt; ut vertical bar V gt; v) of two records coming from students of an undergraduate course, where U is the score of calculus I, scaled in [0,1] and V is the score of physics scaled in [0, 1], the physics subject is part of the admission test of the university. For purposes of comparison, we consider two different undergraduate courses, electrical engineering and mechanical engineering, during nine years, from 2003 to 2011. Through a Bayesian perspective we estimate Prob(U gt; u vertical bar Y gt; v) year by year and course by course. We conclude that U is right tail increasing in V, in both courses and for all the years. Moreover, over these nine years, we observe different ranges of variability for the estimated probabilities of electrical engineering when compared to the estimated probabilities of mechanical engineering.
