Gather initial thoughts and broad opinions about the book.

1. Charles Wheelan opens the book by sharing his frustrating experience with high school calculus to position himself as a guide who values practical application over abstract theory. How did this framing affect your reading experience and your expectations for the book? If you’ve encountered Darrell Huff’s classic, How to Lie with Statistics, how would you compare Wheelan’s goal of empowering readers with Huff’s aim of exposing statistical deception?

2. What was the single most surprising or counterintuitive concept you learned from the book, such as the solution to the Monty Hall problem or the idea of reversion to the mean?

3. Did you finish the book feeling less intimidated by the data you encounter in the news and daily life? In what specific ways has your perspective on headlines, polls, or studies changed? What skills from the book do you imagine yourself using most often?

Encourage readers to connect the book’s themes and characters with their personal experiences.

1. The book shows we use statistics regularly without realizing it, citing examples like sports averages. Think about a hobby, job, or personal interest where you interact with data. How has reading this book changed the way you think about the numbers in that part of your life?

2. What about Wheelan’s discussion of common probability errors, like the gambler’s fallacy or misjudging risk, resonated with your own experiences?

3. Think about the concept of perverse incentives, where a metric designed to improve performance ends up encouraging negative behavior, like in the Houston schools scandal. Where have you seen a similar dynamic play out in a workplace, school, or community setting?

4. How do you feel about algorithms that use correlation to shape your choices, from Netflix recommendations to targeted advertising? Does understanding the statistical mechanisms behind these tools, as Wheelan explains them, make you feel more comfortable or more wary of their influence on your decisions? Does it change how you interact with them?

5. Wheelan uses the concept of expected value to explain why buying lottery tickets or extended warranties on inexpensive items is generally a poor financial choice. Has this discussion prompted you to re-evaluate any small financial risks you take?

Examine the book’s relevance to societal issues, historical events, or cultural themes.

1. The 2008 financial crisis and the failure of the Value at Risk (VaR) model serve as a central cautionary tale in the book. What does this story suggest about our society’s reliance on complex models to manage risk, especially when those models create a false sense of security? Where do you see similar levels of trust placed in predictive algorithms today, for better or worse?

2. What does the discussion on polling, particularly how question wording and sampling methods can produce dramatically different results, suggest about the nature of measuring public opinion in our society?

3. The conclusion raises ethical questions about data privacy with the example of Target identifying a pregnant teenager from her purchasing habits. In the years since this book was published, this issue has become even more central to public debate. How have your own views on the trade-offs between data-driven convenience and personal privacy evolved?

Dive into the book’s structure, characters, themes, and symbolism.

1. Wheelan frequently uses analogies to make complex topics accessible, such as comparing the Central Limit Theorem to LeBron James or data quality to a quarterback’s offensive line. Which of these comparisons did you find most effective in clarifying a difficult idea? How does this rhetorical strategy contribute to the book’s overall tone and argument?

2. What did you think of the book’s structure, which builds from descriptive statistics to probability and finally to more complex tools like regression analysis?

3. Wheelan crafts a distinct authorial persona as a friendly, pragmatic guide who wants to make statistics intuitive. How did this voice affect your engagement with the material?

4. How does Wheelan develop the central theme that correlation does not imply causation? What rhetorical tools does he use to get this point across in different chapters and examples?

5. Wheelan dedicates significant time to how statistical are misused, as in the chapters on deceptive descriptions and regression mistakes. In what ways does Naked Statistics serve as a modern toolkit for spotting statistical manipulation?

6. In what ways do the case studies, like the Whitehall studies on stress or Esther Duflo’s poverty research, function as “intellectual detective stories” within the book?

Encourage imaginative and creative connections to the book.

1. The conclusion poses five major questions statistics can help answer, from the future of football to the fight against global poverty. If you were to add a sixth question to this list reflecting a critical issue today, what would it be? Which statistical tools or research designs from the book would you propose using to begin answering it?

2. Imagine you have to explain the difference between the mean and the median to someone who hasn’t read the book. Using Wheelan’s style, what simple, memorable story or analogy, like “Bill Gates walks into a bar,” would you create?

3. Let’s get creative with the “mandatory warning label” concept Wheelan applies to regression analysis. Pick a common statistic you encounter in daily life, such as a weather forecast’s “percent chance of rain,” a food’s nutrition label, or a political poll’s margin of error. What would your warning label say to help people interpret it more wisely?
