How can I setup segments to manage my quotas?

Segment assignments are used to group respondents for quota and stratificaiton control

For example you might segment by gender as below.

What this achieves is the following

- You can now control quotas in the live screen
- any deck allocations will be independent by segment
- this includes experiments

This means that random-without-replacement allocations in one segment won’t cannibalise the other.

Thanks, but how do I set up quotas in Survey engine? For e.g. postcode screen-out: that when after a certain number of people from one postcode area, new people from the same postcode will be screened out.

For a manageable number of segment, say 20-30 you would set up a segment per postcode. Just add a segment assignment after where you collect the postcode.

Say the postcode question has the label pcode

Then each segment would be assigned with the relevant display\_condition e.g the bondi beach segment would have display condition:

($pcode eq ‘2026’)

In practice you can do this for every postcode.

Then (after publishing) each segment defined can have it’s own quota.

Thank you, this helps me to continue!
