The Statisical Project Competition for Secondary School Students has been an annual event of the Hong Kong Statistical Society since 1986/87. This year, a team from our school joined the competition and won the Third Prize in the Junior Section. The team members collected statistical data about environmental protection in Hong Kong and analysed with reference to the official measures in alleviating the air pollution problem and designed a poster for the competition. The project title is "Government policy can effectively improve our Air Quality"
