So, just what is a normal cat? How could a student explain what normal is? Is it easier if you have numbers? Why or why not? What do you do with nonnumerical or categorical data? Can a cat have a mean (average) fur color? If not, how would you describe "normal" fur color. What kinds of charts or graphs would help? Is a sampling of 14 cats enough to represent all of the cats in the world? If not, how many should be sampled?
