| 中文摘要: |
| 调查安徽某独立学院在校大学生婚前性行为发生的比例，为保护大学生的个人隐私，设置敏感问题Simmons模型对“你是否发生过婚前性行为？”问题进行调查，采用随机应答技术，结合全概率公式及方差的性质，应用CochranW.G抽样理论，给出各层各阶段大学生婚前性行为发生比例的估计值及方差，该调查方法及其统计公式科学、有效。调查结果显示大学生婚前性行为发生比例高。 |
| 英文摘要: |
| The ratio of undergraduate’s premarital sex has been investigated in some university of Anhui province. To investigate the problem of sensitive question of "Have you ever had sex before marriage", we have set up Simmons model for protecting the personal privacy of undergraduate. Using random response technology, we have combined complete probability formula and the property of variance and applied the CochranW.G sampling theory. The estimated value and variance of the rate of all levels and stages of undergraduate’s premarital sex are provided. This investigation method and its statistical formula are scientific and effective. According to the survey, the ratio of undergraduate’s premarital sex is high. Furthermore, we have to strengthen sexual moral education for college students. |
