Survey length calculation

How to calculate the length of the survey in survey solutions

This can be the time between the first assignment is made and the last interview completed (or better approved).

Survey Solutions doesn’t automatically calculate the survey duration, since there is always a possibility remaining that the survey coordinator adds more assignments in a survey in the future.

If you are having a data export from Survey Solutions, you can calculate the survey duration using the information from the assignment__actions and interview__actions files taking the difference between the maximum timestamp in the latter and the minimum timestamp in the former.

Hope this helps, Sergiy Radyakin
