Not Panels, It's Engagement!

When it comes to sampling we need to think about a number of things. And perhaps there are two things which are not often discussed that go beyond quotas, randomisation, databases, profiling, sample and all of the usual jargon....

- outsource de-duplication to ensure the same panelist doesn't complete the same survey from two different sample sources

- some balancing of the sample from the database. Without this it is difficult to make results replicable and robust
