The professor also wants to determine whether there are differences in course points based on delivery environment (online, residential) and race. If he finds differences, then he may realize that,1) he will need to evaluate his course ethnic sensitivity, 2) he may be a more effective teacher in one environment than in the the other, 3) he needs to adapt some of his teaching methods, and 4) one learning environment may be more effective for one race than the other. As a result of these findings, he asks the following question: Do students differ in terms of the points they earn in the course based on race and delivery environment?
