What is the Rigorous and Accelerated Data Reduction (RADaR) Technique in Qualitative Research?

The rigorous and accelerated data reduction (RADaR) technique in qualitative data analysis is a technique that uses a team-based approach to coding and analyzing qualitative data.

The RADaR technique was developed for the purpose of analyzing various types (e.g., focus groups, interviews, case studies, existing documents, etc.) and quantities (e.g., 5 case studies, 12 individual interviews, 8 focus groups, etc.) of qualitative data for the purpose of pulling out relevant data that can be incorporated into one or two specific project deliverables. These project deliverables could range from peer-reviewed manuscripts for scientific journals to a thesis, final project report, conference presentations, book chapters, and health promotion materials.
