Check Your Understanding

1. How should you present your investigation?

Answer: Start with why this claim matters (hook). State the claim. Walk through your investigation step by step. Show evidence. Deliver your verdict. Take questions.

2. What visuals should you use?

Answer: Show the original claim, any graphs you evaluated (annotated with your findings), your own comparison graphs if applicable, and a clear verdict slide.

3. What if the audience disagrees with your verdict?

Answer: Welcome it! Disagreement means they are thinking critically too. Ask them to share their evidence and have a respectful discussion. Being open to challenge is what real data scientists do.

4. What does it mean to be a Data Detective for life?

Answer: It means you never stop questioning. Every headline, every ad, every claim — you ask: Where did this data come from? Who collected it? Is it fair? What is missing? These questions protect you.
