The Art of Statistics: How to Learn from Data book club questions

1. 1.

   Spiegelhalter argues that statistical literacy is as important as reading literacy. Do you believe that? Where did your own statistical education fall short?

2. 2.

   Think of a health claim you've accepted based on reported statistics. What would you now look for to evaluate whether it was well-supported?

3. 3.

   The book shows how the same data can be presented to seem alarming or reassuring depending on the framing. Where in your media consumption do you notice this most?

4. 4.

   Spiegelhalter distinguishes personal risk from population risk. How do those two things interact when making decisions about your own health or safety?

5. 5.

   What's the most statistically dubious claim you've heard repeated as fact? What would you need to see to disconfirm it?

6. 6.

   The book covers the replication crisis. How should that change how much weight you give to any single study?

7. 7.

   Spiegelhalter makes the case for expressing probabilities as expected frequencies. Have you found that framing changes how risks feel to you?

8. 8.

   Where in your professional life do you make decisions based on data? What assumptions in that process do you rarely examine?

9. 9.

   What does it mean to say a statistical model is 'good'? Can a model fit data well and still be misleading?

    Spiegelhalter argues that good visualization is an art as well as a science. What makes a chart trustworthy versus manipulative?

11. 11.

    How do you personally communicate uncertainty to people who want a definitive answer — in your work or family decisions?

12. 12.

    The book ends with a discussion of algorithmic decision-making. What statistical responsibilities come with using an algorithm to decide who gets a loan, a job, or medical treatment?

How to run the discussion

• Pick six to eight, not all of them. An hour of real discussion covers fewer questions than anyone expects, and racing the list is what makes a book club feel like homework.
• Open with what people noticed, not what they concluded. Asking for a verdict first hardens opinions before anyone has heard each other.
• Let the disagreement run. The questions below that split a room are the ones worth the time; the ones everyone answers the same way can be skipped.
• Ask the quiet person a specific question. A direct, narrow question is far easier to answer than an open invitation to contribute.
