Survey has been widely used as a data collection method for both academic and administrative research. Different modes of conducting surveys have been created and continuously developed (Groves, 2011). With the fast-growing penetration of smartphones and other mobile media, survey researchers are faced with the challenge of how to make use of them in surveys while ensuring high data quality and minimizing bias in the coverage (Watson, Zamith, Cavanah & Lewis, 2015). It is especially important to note that Web surveys are now displayed on different devices with different screen sizes and entry methods. So how response entry devices affect response quality is another important question for survey researchers. This study attempts to address these issues by examining the effects of survey modes and response entry device on response quality.
