Abstract

In this paper we have given a methodology to estimate the correlation coefficient be- tween Combined Admission Test (CAT) score and Cumulative Grade Point Average (CGPA) of the students by truncating the CAT score at different cut-off points. An expression for asymptotic variance of estimated value of correlation coefficient has been derived for testing the hypothesis H0: $ho$ = 0 against the alternative H1: $ho$ extgreater 0.
