I used pretty much the same question items year after year or until a new textbook was introduced. Only the data sheets would change. There were no surprises about exam questions. I have always believed students improve learning in statistics if they are not confronted with the unexpected in a given time frame. The idea is to get the correct response and make the appropriate statistical decision. The other great thing about this was (for those of us lazy souls) one did not need to prepare completely new exams each term...only the data sheets. This system might not work for all, but it might for some. . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
