This thesis tests the relative efficiency of Fischer's approach of Chi-square on Affinity viewing time profiles to the more commonly used deviance differential approach. Through his use of a Chi-square approach, Fischer has attempted to make a norm-referenced, comparison of ipsative scores generated using Affinity. His goal has been to create an ethically acceptable approach to identifying sexual interest without losing the efficiency generated through the use of the commonly used deviance differential. A Receiver Operating Characteristic (ROC) curve is used to generate the efficiency of each approach and provide results for comparison. These results lead to a discussion of their implications for Fischer's approach of Chi-square, the deviance differential approach, and to the general use of data generated by Affinity.
