Interpretation Guide
P-Value
- p < 0.01: Very strong evidence
- p < 0.05: Strong evidence
- p < 0.10: Weak evidence
- p ≥ 0.10: Little to no evidence
Effect Size
- Small: Noticeable but minor
- Medium: Visible to the naked eye
- Large: Substantial real-world impact
Confidence Interval
If this range does not contain zero, the result is typically significant. A wider range indicates less precision.
