## Definition
Hypothesis Testing is a statistical framework for evaluating whether observed data provides enough evidence to reject a null hypothesis in favor of a treatment effect.

## Core Principles
- State null and alternative hypotheses clearly
- Choose an appropriate test for the data type
- Set the decision threshold before the experiment starts
- Interpret p-values alongside practical significance
