About this book

Chapter 9: The modelling project

The 20% component: choosing a problem, building and testing a model, and reporting it against the SEC brief.

The chapter problem

Your own model. You will choose a real situation, build a mathematical model of it, test it against data, and report honestly on where it fails. This chapter is the guide, and the project it describes is worth a fifth of your mark.

Where it is used: The modelling project, and every real problem after school.

Your turn to connect it: What situation in your own life would a model help you decide about?
