Your question is Statistical Significance with Small Samples. 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).
Explain how you determine statistical significance for an experiment with a small sample size.
Discuss how your approach depends on the metric type, sample size, distributional assumptions, and whether the analysis was planned in advance. Address hypothesis testing, confidence intervals, statistical power, minimum detectable effect, and the limitations of relying on a p-value alone. Explain how you would avoid false positives from repeated peeking or testing multiple outcomes.
