摘要
2000年全球实现消除IDD目标,如何评价各省是否“达标”?除依据其标准外,必须科学地制定实施标准的具体方法。作者提出消除IDD“三级二层整群”考核验收抽样方法,是集单纯随机抽样、阶段抽样、分层抽样、整群抽样“四位一体”综合抽样方法。既达到样本例数要求,又具有代表性;既可控制或减少系统误差及抽样误差,又能节省大量人力、物力、才力和时间;是一种科学合理实用的抽样方法。
How will we evaluate whether each province in China has reached the goal which is to virtually eliminate IDD world-wide by the year 2000? Based on the standard of eliminating IDD we now consider that a concrete method to put it into effect must be worked out. In this paper the authors present a method used to examine and accept the elimination of IDD, called three stage-bistratum cluster sampling. This method is a comprehensive one consisting of four portions, i. e. random sampling, stage sampling, stratified sampling and cluster sampling. It is found that the method can represent the whole samplings as well as meet the demand of sample numbers, and that not only can control/reduce systematic error and sampling error but also save time and money and use manpower & material resources sparingly. It is thought to be a scientific and practical method.
