Results for one component not stored - and dataHash question
After several runs of my study, I found that one participant did not have data for a single component within their study. From the application logs, I am certain they accessed that component and spent time on it. After further investigation into the study logs, I found the following for this participant:
The component that did not have data should have appeared on line 4 in the image above. Rather, the UUID on that line corresponds to the component that follows the missing component (for which we do have full data). Moreover, line 5 also corresponds to this following component (so it appears twice here despite only being completed once), and the 'dataHash' is now present. I am not sure how the dataHash should typically appear, but here is what a participant with complete data looks like in my study logs:
- From this, is there any indication as to why we may have not collected data for that component?
- Why does 'dataHash' typically show 'no data', and in what context is the hash present?
