Solutions — Making Sense of Social Data

Solutions to End-of-Chapter Exercises

← Online materials · The book · Français · Last updated: August 2026

These are the solutions to the exercises at the end of each chapter. They are fully worked: the substitution, the intermediate value, the result, and what the result means. Solutions to the exercises inside each section are in the book itself, printed immediately after the exercises they answer.

Do the exercise first. A solution read before the attempt is just more text to read. A solution read after the attempt is a check on your reasoning, and only the second one teaches you anything.

All solutions (PDF)

The complete PDF contains every chapter published so far, and its cover page states the revision date and which chapters it covers. If you downloaded it earlier in the term, download it again rather than assuming it is complete. The per-chapter files below are the same solutions, split up for anyone who wants one chapter rather than all of them.

Something looks wrong

If a solution disagrees with your answer and you think the solution is the one at fault, you may well be right — tell me. Include the chapter and exercise number. Corrections go on the errata page and into the next revision.
