Welcome to your interview.
The question is on your right: Parametric vs Non-Parametric. 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.
What is the difference between parametric and non-parametric statistical tests, and when would you choose one over the other?
