Charles Lutwidge Dodgson (1832–1898) was an English mathematician who loved to write children’s stories in his free time. The dialogue between Alice and the Cheshire Cat occurs in the masterpiece Alice’s Adventures in Wonderland, written by Dodgson under the pen name Lewis Carroll. These lines relate to our study of hypothesis testing. Statistical tests cannot answer all of life’s questions. They cannot always tell us “where to go,” but after this decision is made on other grounds, they can help us find the best way to get there. “I don’t much care where—” said Alice. “Then it doesn’t matter which way you go,” said the Cat. —LEWIS CARROLL Alice’s Adventures in Wonderland For online student resources, visit the Brase/Brase, Understandable Statistics, 10th edition web site at . 408 Copyright 2010 Cengage Learning.
