Research of Non-sampling Error on Marketing Research Based on Inquiry Approach

抽样误差和系统误差（即非抽样误差）是统计误差的两个组成部份。

Sampling-error and system-error ( non-samplingerror ) are two components of statistical error .

浅谈问卷调查中非抽样误差的控制

On Control of Non-sampling Errors in Questionnaire

本文探索了将多阶模型应用于非抽样误差研究的思路。

This paper explores the way of using multilevel model in the study of non-sampling errors .

非抽样误差问题研究

Non-sampling Error Question Research

控制非抽样误差的主要方法是在调查操作的每一过程环节都采取有效预防措施。

And to take effective preventive measures in every procedure is proved to be the main way to control nonsampling error .

这个指标描述了由异质性而非抽样误差引起效应变异的百分比。

This describes the percentage of the variability in effect estimates that is due to heterogeneity rather than sampling error ( chance ) .

本文研究了国内外非抽样误差测度的主要方法，将其分为两类：基于设计的方法和基于模型的方法。

This paper studies the main techniques of measuring non-sampling error and classifies them into two classes : based on designs and based on models .

在恰当设计的程序中，多阶模型能够比传统方法更好地拟合样本数据的特征，实现非抽样误差的测度与调整。

Multilevel model can simulate the characteristics of sample data batter than conventional methods with correctly designed programs and realize the measurement and adjustment of non-sampling errors .

在抽样调查中，非抽样误差产生的原因十分复杂，且种类繁多，其对整个抽样调查的影响是不容忽视的。

Reasons which caused non-sample errors are complicated and various in sample investigation , and the influence on the whole sample investigation g should ′ t be neglected .

本文结合调查误差分析的理论，根据网络自身的特点，分析了网络调查的非抽样误差的来源，并提出了减少误差的方法。

With theory of error analyzing and characteristics of Internet , this article analyzes the non-sampling errors of Internet surveys and comes up with some steps to reduce them .

非抽样误差是统计调查中除抽样误差以外，由于各种原因而引起的误差，对调查结果的影响非常大。

Except of sampling errors , Non-sampling errors are aroused by all kinds of reasons in statistical survey , and the more important , they can affect the result of survey badly .

相对于抽样误差理论而言，非抽样误差理论研究存在明显的差距，且至今尚未形成严密的体系。

There is still obvious distance between the theory of Non sampling Error and the one of Sampling Error , and so far there is not a complete theoretic system coming into being .
