Mielipidemittaukset ovat Suomessa perinteisesti olleet verrattaen tarkkoja. Esimerkiksi vuoden 2015 vaaleissa jokainen kolmesta säännöllisesti kannatuskyselyitä toteuttavasta tahosta oli viimeisessä mittauksessaan keskimäärin reilun puolentoista prosenttiyksikön päässä vaalituloksesta isojen ja keskisuurien puolueiden osalta.
Kuitenkaan mikään yksittäinen gallupien tekijä ei todennäköisesti saa arvioitua kannatusta täysin oikein, vaikka lähellä ovatkin. Usemman mielipidemittauksen painotettu keskiarvo antaa yksittäistä mittausta kattavamman kuvan tilanteesta.
Alla on kuvattu paitsi kotimaassa säännöllisesti puolueiden kannatuksia mittaavien tahojen mielipidemittauskeskiarvo siten, että se on painotettu kunkin mittauksen otantamäärällä, myös yksittäiset mittaukset sellaisena kuin ne on julkaistu. Kyseessä on siten keskiarvo, jonka kautta voi arvioida puolueiden kannatustasoa. Koska mittaajat ovat kotimaassa niin harvassa ja mitttavat puolueet niin moninaisia, ei alla yritetäkään oikaista mahdollisia mittaajan sisäisiä epätarkkuuksia. Listauksessa virhemarginaalit ja kannatukset ovat listattuna mittaajan esittämässä muodossa.
