Naked Statistics
Stripping the Dread from the Data
by Charles Wheelan
Brief overview
This book demystifies the world of data, probability, and statistical methods in a lively, down-to-earth manner. It shows how numbers both inform and deceive us, and how a few core principles of statistics can reveal hidden truths or uncover errors in everyday life. By journey’s end, you’ll see how to better interpret figures, ask sharper questions of data, and spot misleading conclusions.
Why Numbers Matter
We start with a simple truth: numbers have the power to shape how we see the world. Everyday, we rely on percentages to evaluate success rates, interpret polls that gauge public opinion, and trust graphs that detail economic trends. Yet, it’s easy to forget that these figures come from data that can be incomplete or biased.
In this book, you’re invited to peer behind the curtain to see how raw data becomes a story—whether that story is accurate or intentionally bent to mislead. And you’ll learn that even slip-ups in data collection or analysis often occur without any bad intentions. A misunderstood chart or a single faulty assumption in a big dataset can send whole decisions awry.
Drawing on a wide range of real-life anecdotes—from job statistics in public offices to extreme lottery winners—we’ll unravel the crucial concepts that can sharpen your skill in interpreting the blizzard of data all around you. There’s no need to be a math whiz: the main ingredient is curiosity.
The Power and Perils of Averages
When we think of a 'typical' value, we often reach for the average. Yet the mean can be hijacked by outliers—like a single billionaire who skews the income figures for an entire town. That’s why the median, which splits a group exactly in half, can sometimes reveal a more meaningful 'middle.'
Consider salaries in a small company. If the owner rakes in millions, the mean salary sounds quite high, but the median reflects what most employees earn. By understanding this nuance, we see how policy debates on 'middle class well-being' can become distorted if only a single metric—like average wage—dominates the conversation.
In daily life, the difference between mean and median resonates everywhere: housing prices, test scores, or even credit card debts. Recognizing when to use one, the other, or a combination keeps us from being fooled by extremes. Think of it like choosing the right lens on a camera: each lens captures reality, but from a distinct angle.
