ODK Collect. A way to avoid duplicating a collected information

Hi Guys

Is there a way to avoid collecting the same information on different
devices or even on the same device.
example of a household survey, a house can be visited twice by the same
device filling the same form. ODK collect allows that to happen therefore
obviously that will create a duplicate.

not sure if i make sense

Hey remember ODK is just the tool, we are the users of the tool. Whatnwe
did was divide up the collectors into team so folks target different homes
and not the same.

We however still had slippage.

Nope.

Minimizing this needs to be part of your survey campaign planning.

And data cleansing, curating and validation, where you would detect and
consolidate or remove duplicates, needs to be part of your data processing
sequence.

One thing that helps is making sure you include metadata in your form.
instanceID, deviceID, startTime and endTime will help a lot when you
are cleaning data.
