Abstract : This study was designed to examine the effectiveness of using two methods of comparing relevant and control questions. A mock homicide scenario was set up using a sleeping, female mannequin. A thief was burglarizing the room. While attempting the robbery, the female woke up causing the thief to kill her. A total of 120 subjects were used for training, piloting and data collection. Tests were analyzed by polygraph instructors who were blind to the programmed condition. The first comparison involved comparing the relevant questions to the overall strongest control question. The second comparison consisted of comparing the relevant question to the strongest and closest control question. The study results showed the evaluation of the tests using the strongest control and the strongest and closest control were not significantly different.
