The purpose of this article is, first, to extend Poon et al.'s (1993) maximum likelihood estimation (MLE) of the correlation coefficient based on interval data to the regression case. Secondly, this paper shows how the traditional method of collecting interval data with the intervals chosen by the researcher cart be easily modified to avoid the problems discussed by Poon et al. (1993). The MLE for this modification to the regression problem is presented. Finally, all the methods discussed in this paper are used to estimate the effects of grade point average and gender on student perceptions of the percentage of their classmates who have cheated on at least one exam in college.
