What is Statistics? And why does it matter?
Statistics is the science of collecting, organizing, and interpreting numerical facts, which we call data.
We are bombarded by data in our everyday lives. The
news mentions movie box-office sales, the latest poll of the president’s popularity, and the average high temperature for today’s date. Advertisements claim that data show the superiority of the advertiser’s product. All sides in public debates about economics, education, and social policy argue from data. A knowledge of statistics helps separate sense from nonsense in this flood of data.
The goal is to learn from data, and in this book you’ll see data from a variety of different areas. Soon enough you’ll be asking yourself “what does the data tell me?”
