About This Tool
QOL Converter Ark provides a disciplined method to map quality-of-life scores between standard scales, enabling consistent interpretation across studies, HR dashboards, and health analytics projects. It focuses on domain logic rather than UI.
Conceptual operation: for each score you select the source scale and target scale, choose an assignment method (direct linear mapping, z-score normalization, or category alignment), and feed the numeric value. The tool computes a converted score using documented formulas and returns metadata such as method and source/target scales.
Beneficiaries include researchers comparing QoL across trials, HR teams reporting employee well-being, and clinicians assessing population health. Differentiators are support for multiple scales, transparent calculation methods, batch processing, and auditable mappings via explicit inputs and outputs.
Core features include input validation, error handling for unsupported scales, and export options for reproducible results and integration into reports.
How to Use
1. Provide inputs: select source scale, target scale, and enter the source score.
2. Choose method: linear mapping, z-score normalization, or category mapping.
3. Run calculation: obtain converted score and metadata.
4. Review outputs: verify converted score, method, and scales; note uncertainty if normalization was used.
5. Export results: download JSON or CSV for pipelines.
