AI Coach

Like having a tutor on every lesson

Ask anything as you learn. The AI Coach has read every lesson, every example, every footnote — and it adapts its answers to your level, your role, and the goals you set.

  • Explains concepts in your own words, with examples from your industry.
  • Pulls quotes and figures directly from Ben Jones's books.
  • Recommends what to focus on next based on your progress.
What's the difference between accuracy and precision when reporting data?
AI Coach
Great question. Accuracy is how close your measurement is to the truth — precision is how close repeated measurements are to each other. A scale that always reads 5lb heavy is precise but inaccurate. A scale that reads anywhere from 1lb light to 3lb heavy is neither.
Show me an example from the course.
AI Coach
In Lesson 3, the survey example reports voter intent within ±3 points — that's the precision. The accuracy is whether the actual election result lands inside that band.
