Full party list from the article's embedded poll chart, whose data record is https://services.api.no/api/empiricus/v1/public/political-poll/experiment/54492 ('Nettavisens partibarometer for september 2025', pollingCompany InFact); article text confirms Ap 26,5, Rødt 7,3, Sp 6,3, SV 5,4, H 13,6, Frp 21,8. Weighting: kjønn, alder, geografi og partivalg 2021. Nettavisen's later 'valgdagsmåling' (8 Sep) is an election-day poll, not a pre-election poll. The release does not state its base; its party shares add up to about 100, so they are read as shares of those naming a party.

Method

Each figure is the pollster’s final published poll before the vote, read from its own release, the commissioning outlet’s report, or an official registry; never from Wikipedia or an aggregator. It is set against the certified count as a share of valid votes. Error is poll minus result, in percentage points; the mean is over the contestants the poll and the count both name. Margin error is the certified winner’s lead over the certified runner-up as the poll had it, minus as it was, and names the one the poll leaned towards. Where the poll’s base differs (for example, all respondents including undecided), the comparison says so. These are measured facts, not grades: we rank no pollster.
