- Measurement bias: Different quality data for different populations
- Evaluation bias: Using inappropriate metrics for different groups

**Algorithmic Bias Types:**
- Allocational harm: Unequal distribution of resources/opportunities
- Representational harm: Reinforcement of stereotypes
- Quality of service: Different performance levels across groups
- Individual fairness: Similar individuals treated differently

**Bias Mitigation Strategies:**

Pre-processing:
- Data augmentation for underrepresented groups
- Re-sampling techniques to balance datasets
- Synthetic data generation for minority classes
- Feature selection to remove protected characteristics

In-processing:
- Fairness constraints in model optimization

- Multi-task learning with fairness objectives
- Regularization penalties for biased predictions

Post-processing:
- Threshold adjustment for different groups
- Calibration across protected classes
- Output modification to achieve fairness metrics
- Human-in-the-loop review for high-stakes decisions

**Real-World Example: Amazon Hiring Algorithm Bias (2018)**
Problem: Resume screening algorithm showed bias against women
Root Cause: Training data reflected historical hiring patterns
Solution Approach:
- Immediate: Discontinued biased algorithm
