Reading 18


Read the following chapters in Introductory Statistics with Randomization and Simulation before class on November 20:

  • Chapter 2: read 2.5, 2.6

    Note: The textbook spends some time discussing how to use Z scores and probability tables for evaluating the normal distribution. If you have a difficult time following that part, do not worry too much about it, focus on the general concept instead of the technical details. The dnorm(), pnorm(), and qnorm() functions in R yield the same information as Z scores and probability tables.

Chapter 2.5 discusses the practical consequences of the Central Limit Theorem and chapter 2.6 discusses the normal distribution.
