  2. What is statistics? • A way of reasoning, along with a collection of tools and methods, designed to help us understand the world. • It is not all about the numbers. • It’s about the data • Data are values along with their context, without context they are just numbers! • Data is plural, datum is singular

  3. Statistics is about variation • Imagine a population at a university you are considering attending. • Suppose that every student was enrolled in the same number of courses, spent the same amount of money on textbooks, and favored increasing student fees to support library services. • In this population, there is no variability in the number of courses, amount spent on textbooks, or student opinion on the fee increase.
