Validation Methods
Systematic approaches to verify the accuracy, reliability, and applicability of research findings, models, or processes.
Validation Methods
Validation methods comprise systematic techniques and procedures used to assess the accuracy, reliability, and applicability of research findings, theoretical models, or practical implementations. These methods are fundamental to ensuring the robustness of scientific inquiry and technological development.
Core Types of Validation
1. Internal Validation
- Assessment of internal consistency and logical coherence
- Verification of methodology and procedural accuracy
- Testing for systematic bias and experimental error
2. External Validation
- Evaluation of generalizability to other contexts
- Testing findings against independent datasets
- Assessment of real-world applicability
- Connection to ecological validity
3. Cross-Validation
- Partitioning data into training and testing sets
- K-fold validation techniques
- Bootstrap validation methods
- Related to statistical sampling techniques
