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).

Define participation clearly, validate the decline, decompose it across relevant dimensions, and distinguish measurement issues from behavioral or operational causes. Recommend follow-up analyses or actions based on the evidence.
