Summary
Correspondence analysis visualizes qualitative data relationships. Tri-Deux software enhances interpretation by directly displaying variable modality connections, aiding in identifying patterns and potential typologies.
Area of Science:
- Statistics
- Data Visualization
- Sociology
Context:
- Correspondence analysis is a favored method for qualitative data.
- Graphical representations aid in understanding modality positions but interpretation can be subjective.
- Existing methods lack direct visualization of modality interconnections.
Purpose:
- To introduce Tri-Deux statistical software for enhanced correspondence analysis.
- To provide a tool for directly visualizing and interpreting relationships between modalities.
- To aid researchers in identifying patterns and potential typologies within qualitative data.
Summary:
- Tri-Deux software visualizes connections between variable modalities based on independency deviations.
- Lines link modalities, weighted by attraction strength, allowing clear distinction between strong and weak associations.
- The software facilitates the identification of how modalities gather or contrast, improving the interpretation of correspondence analysis results.
Impact:
- Improves the objectivity and clarity of correspondence analysis interpretation.
- Enables researchers to more easily discover potential typologies within qualitative data.
- Facilitates a 'return to clinical practice' by making data analysis more intuitive and relevant.
