【摘要】 减少缺失数据是提高“问卷有效率”的重要环节。主要根据统计分析的要求,从技术角度微观地探讨如何在ASP中利用数据库技术防止缺失数据,即通过Recordset对象中Fields集合的字段名(Fields().Name)与网络问卷表单的对象名(Name)进行关联,优化缺失数据校验程序,设计出更简洁、灵活且不受问卷试题规模影响的校验程序,增强了Web问卷的通用性,提高了“问卷有效率”,达到事半功倍的效果。更多还原

Therefore, after the name of a form in a web-based questionnaire is set in relation to the field(s) and the name of the record set up, the verifying program for missing value can be optimized. As a result, the program can be easily transferred to others.更多还原
