ABSTRACT

How data arrive In this chapter we move carefully into the world of numbers and describing measurements and findings in numerical terms – that is, using statistics. As with other concepts in this book, many of the ideas here will be known to you or, at least, you will find that you have used the concepts in your life already many times but perhaps not in a formal way. I will attempt throughout to stick

closely to the everyday experience of statistical things (for instance, working out your average shopping bill or estimating whether we’ve had a particularly rainy month).
