Create an experiment results calculator
Build the significance and effect-size maths into something the team can use without a statistician.
What this prompt helps you do
A calculator artifact taking real inputs and returning effect size, significance, confidence interval, and caveats.
When to use it
Experiment results are being interpreted informally and underpowered tests are being called wins.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Report the confidence interval, not just the verdict; a significant result with a wide interval is barely a result.
How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
