Measurability readout

Reach used: 10.0%
Exposed respondents to recruit: 556
Qualifying respondents required: 5,560
Total survey entrants required: 11,120
Expected control candidates: 5,004
Exposed to at least one campaign: 10.0%

What this means

The exposed group is normally the constraint. A large control pool cannot rescue a tiny exposed base, and a narrower exposure definition will reduce the usable group further.
