    The authors, one a medical statistician, the other a medical educator, gradeeach statistical concept by importance and ease of understanding. Thesegradings help readers pick out concepts that suit their level of understanding,or the most important concepts if they are short of time. The book thereforecaters both for readers that are bewildered by medical statistics and for thosethat want to learn about more complex concepts.
