Last year, sixteen-year-old Roy Christopher K. Ang, a freshman Medical Laboratory Science student from the Saint Louis University-Baguio City bagged the 17th PSQ National Finals. Ang was awarded a cash prize of P25,000.00 and a specially designed trophy, among others. His coach, Nora S. Umalla was also given a certificate of recognition and P12,500.00 cash reward.
The PSQ aims to assess the competency and skills of college freshmen in statistics as acquired from high school. The NSO and the Philippine Statistical Association have been conducting the yearly undertaking since 1992 to promote public awareness and appreciation of statistics. In 1994, the Commission on Higher Education began endorsing the annual competition.
