Скачать или смотреть Misleading Statistics: When Histograms Break the Rules

On the surface, a histogram feels like one of the simplest charts you can make. But in this Street Stats Short, Kevin Keller explains how even a basic histogram can be misleading. When people build histograms, they often break two simple rules: you need (1) equal bin widths and (2) bars that actually touch. Once those rules are broken, the picture you think you’re seeing isn’t actually the process you’re running.

If you work with data visualization, this is the kind of thing that slips by all the time. A few clicks on bin settings can hide outliers and make a process feel tighter than it really is.

This is Lesson 6 in the Street Stats Shorts series on how statistics and “good‑looking” charts can mislead you. It’s your quick reminder to make sure that “nice” graph isn’t quietly misreporting the story.
