Calculation Example
Let's do a sample calculation:
Example:
Test Type:
T-Test (Two-tailed)
Parameters:
t = 2.5, df = 24, α = 0.05
Critical Value:
t₀.₀₂₅,₂₄ = ±2.064
Result:
P-Value:
0.020
Significance:
Significant
Decision:
Reject H₀
Confidence:
95%
Step-by-Step Calculation:
- Identify Test: Two-tailed t-test with df = 24
- Find Critical Value: t₀.₀₂₅,₂₄ = ±2.064
- Compare Values: |2.5| > 2.064, so in rejection region
- Calculate P-Value: P(|T| > 2.5) = 0.020
- Make Decision: P < α, so reject null hypothesis
