Scenario 1. Suppose your instructor informs the class that the highest grade on each of
his multiple-choice exams will automatically receive a 100. All other grades below this
will be based on this high grade. For example if the highest grade is an 80 this would
receive an automatic 100. If someone scores a 40 then the grade earned would be a 50
[(40 80) * 100%)]. To the instructors surprise all the students earned a 100 on the first
exam even though their grades were all an identical 25%. How could this have
happened?
Using the scenario above what might the instructor do to avoid this same result?
