Your question is Design Decisions With Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you validate your design decisions using data rather than intuition?
Explain the practical process you use to define measurable hypotheses, select appropriate evidence, and decide whether to proceed, iterate, or abandon a design direction. Include how you align stakeholders, account for qualitative and quantitative evidence, and measure outcomes after release.
