Welcome to your interview.
The question is on your right: Validity and Reliability in Research. 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.
You are reviewing a research readout from a user study on a home-buying flow. The team wants to know whether the findings are valid, whether the measurement is consistent, and how much confidence to place in the result.
How do you ensure the validity and reliability of your research findings?
