Background:

Read Chapters 13-15 of the book What is a p-value anyway? by Andrew Vickers. (Sam and Joe will have handed copies out already.) Respond to the circled discussion questions at the end of each chapter. Remember, length of response is not as important as how well and how clearly you communicate your well-formed thoughts in the response. Please avoid run-on sentences. You may use the outline below to frame your responses. Try to respond in such a way so that the reader can tell what the question was without having to write the question out before your answer.
