The chart looked good. The question that matters: are the numbers real?

Earlier in this course, you handed over a file and got answers: a summary, a chart, numbers. If you've caught yourself wondering "how do I know they're right?", congratulations: that question is the skill, and today it gets an answer.

The people who build these tools ask the same thing. Their own guide tells you to check the work before you rely on it, and they built the tool to show that work when asked. Most people never ask.

Today you ask. On the answer you already have.
