Sports analysis report 'white' data: Why background information is vital

The article discusses an alarming incident in the sports analysis world: a pre-match badminton analysis report contained only 'N/A' (insufficient information) across all sections. A sports scientist reflects on the importance of data, from technical analysis to world rankings, and argues that without solid information, analytical conclusions are meaningless. The commentary stresses the need for Vietnam to build national sports databases, using examples from badminton and lessons from football. The author highlights that admitting data absence is better than falsifying numbers, and calls for systematic data collection in Vietnamese sports.
