Hypothesis Testing and P-Values
P-Value Definition
The p-value is the probability of observing a statistic as extreme (or more extreme) as the sample statistic, assuming the null hypothesis (H₀) is true.
Interpretation
- Large p-value: Evidence in favor of H₀ (Null Hypothesis).
- Small p-value: Evidence in favor of Hₐ (Alternative Hypothesis).
Types of Errors
- Type I Error (α): Rejecting H₀ when H₀ is true.
- Type II Error (β): Failing to reject H₀ when H₀ is false.
