On the Basis of records form 57 soccer games played in 2003 Credit Suisse First Boston Hong Kong Sevens, this research paper intends to apply canonical correlation to the investigation of 11 offense/ defense techniques in terms of (1) CP: completed passes, (2) PK: possession kicked, (3) EM: errors made (4) TOW: turnovers won, (5) ET: effective tackles, (6) MT: missed tackles, (7) SW: scrums won, (8) LW: lineout won, (9) PC: Penalties conceded, (10) RE: restart errors and (11) TI: team involvement, which may bring about influences to scores counted/uncounted in a game. Research findings point out that canonical correlation coefficients between the 11 offense/defense techniques and tries /losses of scores are p1=.708 and p2=.609 in each instance; both reach a significant level (p….). The crucial role played in canonical vitiate n1 appears to be MT, which results in positive correlation to tries and negative correlation to losses for scores. The order of importance to the canonical vitiate n1 can be defined as LW, PK , and ET, among which LW and ET have positive correlation to tries, while maintaining negative correlation to losses for scores. This research paper concludes that the application of analyzing canonical variates to 11 offense/defense techniques employed in 2003 Credit Suisse First Boston Hong Kong Sevens have brought about significant correlation and interpretations to tries and score losses. Results of this research paper could serve as worthwhile reference fro couches in making training plans and strategies for actual games plays.
