HOW UPWEIGHTING WORKS

Gold Standard pollsters receive an effective sample size inflation of n′ = n × (m²) where m = 2, so √n′ = 2 × √n. This means their contribution to the daily weighted average is doubled relative to standard pollsters of equivalent raw sample size. The upweight applies only when PSI minimum disclosure items (field dates, sample size, sample type) are present in the release.
