Your question is Experiment Speed vs Statistical Rigor. 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).

Problem

Scenario

You're running product experiments on surfaces like Asana Inbox, task creation, or project onboarding. The team wants results quickly, but shorter tests and repeated looks at the data can weaken inference.

Question

How would you think about the trade-off between faster experimentation and statistical rigor?

What this tests

  • How you balance iteration speed against false positive risk
  • Whether you understand power, MDE, and sample size trade-offs
  • Whether you recognize the danger of peeking and optional stopping
