- The minimum detectable difference (MDD) quantifies the smallest difference between treatment and control means needed to identify significant effects, factoring in data variability and defined probability levels.
- MDD helps assess the reliability of effect thresholds in environmental studies, guiding regulatory decisions concerning chemical exposure in plants and ecosystems.
- The paper critiques the existing MDD calculation methods for lacking clear definitions of type II error rates and proposes improvements to enhance their robustness for effective risk assessment outcomes.
