experiment-design

Design experiments that actually prove something. Most A/B tests fail because they test vague ideas, run too short, or peek at results. A well-designed experiment has a clear hypothesis, adequate power, and a pre-committed analysis plan.

Every experiment starts with a written hypothesis before any work begins:

"If we [make this specific change] for [this audience], then [this metric] will [change in this direction] by [this amount], because [this reason based on evidence]."

使用正确的方法设计假设驱动的实验和 A/B 测试。当被要求设计 A/B 测试、验证假设、计划实验或为产品变更设置测试时使用。涵盖假设写作、样本量和常见错误。 来源：assimovt/productskills。
