Professor Karl$$s class has a DFW rate of $75\%!$ DFW stands for dropped, failed, or withdrawn, and it shows the percentage of students who do not succeed. The college wants to keep DFW rates below $30$ percent, on average. The class is Business Statistics, a difficult class. Perhaps the students are ill$-$prepared, or perhaps Professor Karl$$s course is harder than necessary. What step should the Dean take next?
