A criminal justice professor is interested in the relationship between her students' seating position and their performance in class. She believes that the better students sit in the front or the room while the poorer students sit in the back. To investigate this relationship she ranks the students by class performance and categorizes their seating as either "front" or "back." Which statistical procedure would you apply to test the hypothesized difference in class performance based on seating position?

		Chi-square
		t-ratio
		ANOVA
		Median test
