1. Weighted results mean that the overall response rate was at least 60%. The overall response rate is calculated by multiplying the school response rate times the student response rate. Weighted results are representative of all students in grades 9–12 attending public schools in each jurisdiction. With weighted data, it is possible to say, for example, "X% of students in territory Y never or rarely wore a seat belt when riding in a car driven by someone else." 2. Unweighted data represent only the students who completed the survey.
