hi all, i am designing survey in Qualtrics and I already use the " Prevent Ballot Box Stuffing." However, when I launched the survey in MTurk, i found there are lots of duplicate IP address so respondents clean their cookies and/or use another device. but my research and filter questions need one respondent only fill in survey once. How can I avoid this? many thanks for your help and solutions.
hi all, i set up a filter question for occupation, like "Which of the following categories best describe your employment status?" and if respondent does not choose choice 1 "working more 20 hours per week" OR choice 2 "working 1-19 hours per week" , they should end the survey but i only can set up only one choice. i do not know what's wrong with my setting. i checked several times and i failed to find mistakes.
