Replication Data for: Questions of Quality - Is Data Quality Still Tied to Survey Mode?

The increasing popularity of online surveys in the social sciences led to an ongoing discussion about mode effects in survey research. The following article tests if commonly discussed mode-effects (e.g. sample differences, data quality; item-non response, social desirability and open-ended question) can indeed be reproduced in a non-experimental mixed-mode study. Using data from two non-full-probabilityrandom samples, collected via an online and face-to-face survey concerning itself with opinions on migration and refugees, most assumptions found in experimental literature can indeed be replicated via research data. Thus, the mode effects need to be accounted for if the usage of mixed-mode designs is necessary, especially if online surveys are involved.

社会科学领域内线上调查的日益普及，引发了调查研究中关于调查模式效应（mode effects）的持续讨论。本文旨在检验学界常讨论的各类模式效应（如样本差异、数据质量、项目无应答、社会称许性偏差以及开放式问题相关效应），是否可在非实验性混合模式研究中得到复现。本研究依托两项通过线上与面对面调查收集的、聚焦移民与难民议题的非全概率随机样本数据，最终复现了实验文献中多数已提出的研究假设。因此，当研究必须采用混合模式设计时，尤其涉及线上调查时，需充分考量模式效应的影响。
