by removing bad respondents and designing surveys that keep good respondents engaged. Research pro- fessionals now have evidence that survey design not only influences whether respondents abandon a survey but also impacts the data for those who complete it. The ability to predict the effect of various survey design variables on respondent engagement will help survey designers maximize engage- ment to increase the reliability of their data.
