Two hundred and thirty-seven seventh- and eighth-grade students were assessed for levels of drug/alcohol use, involvement in extracurricular activities, peer influence, and personal attitudes. Cross-tabulations and the chi-square test of independence were used to statistically compare the three groups (non-users, users, and abusers). Several trends emerged from the data.
对237名七年级和八年级学生的毒品/酒精使用水平、课外活动参与情况、同伴影响和个人态度进行了评估。交叉表和独立性卡方检验被用于对三组（非使用者、使用者和滥用者）进行统计学比较。数据呈现出几个趋势。
