Welcome to your interview.

The question is on your right: Explaining P Values Clearly. Take a moment with it first.

Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.

Problem

Scenario

You are presenting results from a model validation or policy test, and a stakeholder asks whether the result is "statistically significant" and what the p-value actually means. You need to explain it in plain language without losing the statistical meaning.

Question

What is a p-value, and how do you explain its statistical significance to a non-technical stakeholder?
