Hi everyone,
in my survey I randomized the blocks that appear to each respondent. 50% of the respondent get the full questionnaire, while the remaining 50% gets a shorter version. The idea is to understand if a shorter questionnaire also encourages respondents to complete the training faster. While it is easy to understand which version of the questionnaire respondents who completed the survey got, simply by looking at missing answers, I do not know how to retrieve which blocks those who did not finish the survey would have seen. Do you have any clue of how I can do this?
Thanks in advance for your help!
Best,
Marco
