Abstract
To investigate the possibility of detecting match-fixing, this study aims to verify whether the number of rallies in universal and anomalous badminton matches follows Benford’s law. The study counted the number of rallies in 685 international badminton tournaments selected through purposive sampling and analyzed the first significant digits of the rally data through the χ2 test and intra class correlation coefficient. Of these, two well-known fixed badminton matches were found to be anomalous, and hence, the finding is that the number of badminton rallies in universal matches follows Benford’s law while the anomalous matches do not do so.
