[ , ] Kwisahluko, ndaba ezihle kakhulu malunga post-abahlulwe. Nangona kunjalo, oko akuthethi akusoloko ukuphucula umgangatho uqikelelo. Ukwakha imeko apho anokuthumela-abahlulwe ziyakwazi ukunciphisa umgangatho uqikelelo. (Kuba uthsuphe, bona Thomsen (1973) ).
[ , , ] Design kunye kuqhuba isaveyi non-linokuba on Amazon MTurk ukuze ubuze malunga ubunini umpu ( "Ngaba, okanye nabani na endlwini yakho, nompu, umpu okanye ngomva? Ingaba wena okanye omnye umntu kwikhaya lakho?") Kwaye ukuziphatha yolawulo lwemipu ( "Yintoni ocinga ukuba ibalulekile-ngaphezulu ukukhusela ilungelo Merika banemipu, okanye ukulawula ubunini umpu?").
[ , , ] Goel noogxa (2016) lenze uphando non-linokuba-based ebandakanya imibuzo 49 multiple-choice attitudinal avela Jikelele Social Survey (GSS) kwaye khetha uphando ngokuthi iPew Research Center on Amazon MTurk. Bakugqiba nyenyisa ngenxa non-nokumela data usebenzisa imodeli-based post-abahlulwe (Mnu P), uze uthelekise ngawoqikelelo oluhlaziyiweyo nabo kuqikelelwa usebenzisa iisaveyi GSS / Pew ezinokwenzeka-based. Kuqhuba isaveyi ofanayo MTurk kwaye sizame senze ngokufanayo kuMfanekiso 2A Figure 2b ngokuthelekisa liqikelela olulungisiweyo kunye noqikelelo ukususela kwimijikelo zakutshanje ze GSS / Pew (Funda isiHlomelo Table A2 uluhlu lwemibuzo 49).
[ , , ] Izifundo ezininzi zisebenzisa amanyathelo self-ingxelo mobile data umsebenzi yefowuni. Esi sicwangciso umdla apho abaphandi bakwazi ukuthelekisa ukuziphatha self-ingxelo yokuziphatha ezifakiweyo (jonga umzekelo, Boase and Ling (2013) ). izimo ezimbini eziqhelekileyo ukubuza nibiza kwaye ngefowuni, kwaye izakhelo ezimbini ixesha eziqhelekileyo malunga ngala "izolo" kwaye "kule veki iphelileyo."
[ , ] Schuman kunye Presser (1996) bathi imiyalelo mbuzo azilithetheleli iintlobo ezimbini ubudlelwane phakathi imibuzo: Imibuzo yinxalenye-yinxalenye apho lo mibuzo mibini kumgangatho ofanayo Okukodwa (umzekelo amanqaku abaviwa ezimbini kamongameli); kunye nemibuzo yinxalenye-wonke apho umbuzo jikelele lulandelayo umbuzo kakhulu ethile (umzekelo, becela "Waneliseke kangakanani umsebenzi wenu?" elilandelwe ngu "Waneliseke kangakanani bubomi bakho?").
Ke ngakumbi ubeluphawu iindidi ezimbini isiphumo umbuzo umyalelo: iziphumo ngokufanayo xa iimpendulo kumbuzo kamva ziziswa kufutshane (kunokuba ngenye indlela) kwi benikelwe umbuzo ngaphambili; kwahluke iziphumo xa kukho umahluko omkhulu phakathi iimpendulo kwimibuzo emibini.
[ , ] Ukwakha kumsebenzi Schuman kunye Presser, Moore (2002) uchaza njengomlinganiso eyahlukileyo isiphumo umbuzo umyalelo: isongezo, kunye yeyeemeko apho. Nangona uthelekiso kunye ukungqinelana neziphumo ziveliswa njengesiphumo uvandlakanyo abaphenduli 'lwezinto ezimbini ngokunxulumene kwabanye, wongezelelo ngamnye kunye neziphumo yeyeemeko ziveliswa xa wenza abaphendule olubuthathaka kakhulu-sikhokelo ezinkulu ngaphakathi apho imibuzo ebuziweyo. Funda Moore (2002) , ke ngoko bayile baze benze uvavanyo uphando kwi MTurk ukubonisa isongezo, okanye yeyeemeko iziphumo.
[ , ] Christopher Antoun noogxa (2015) laqhuba uphando sithelekisa iisampuli lula efunyenwe ezine ezahlukeneyo online imithombo ukugaya: MTurk, Craigslist, Google AdWords kunye Facebook. Yila uphando elula nokuqesha nxaxheba kwimithombo ubuncinane ezimbini ezahlukeneyo online ukugaya (inokuba imithombo eyahlukeneyo ukusuka imithombo ezine ezisetyenziswa Antoun et al. (2015) ).
[ ] YouGov, umntu esekelwe kwi-intanethi lemfuna ngokuqinileyo, kuqhutywa ngokweentloko ekhompyutheni ligqiza malunga 800.000 baphendula UK kwaye asetyenziselwa uMnu P. ukuqikelela isiphumo EU Uvoto (oko kukuthi, Brexit) apho lwabavoti UK ukuvota nokuba ukuhlala okanye ashiye European Union.
Inkcazelo eneenkcukacha imodeli statistical YouGov yeyona apha (https://yougov.co.uk/news/2016/06/21/yougov-referendum-model/). Kalukhuni ukuthetha, YouGov Ulwahlulo lwabavoti ngokwendidi ngokusekelwe 2015 unyulo jikelele ukhetho ivoti, ubudala, iziqinisekiso, isini, umhla ndlebe, kwakunye elisemthethweni abaphila kulo. Okokuqala, bona basebenzisa data eqokelelwe panelists YouGov ukuqikelela, phakathi kwabo ngubani ukuvota, inani labantu yohlobo lwabavoti ngamnye banenjongo ukuvota weKhefu. Baye baqikelela kaGrant uhlobo lwabavoti ngalinye ngokusebenzisa 2015 British Study Election (BES) lwangaphaya konyulo ubuso ngobuso phando, kungqinisiswa enithe evela kwizixa lonyulo. Ekugqibeleni, baqikelele bangaphi abantu kukho kuhlobo ngalunye ngumvoti kwabavoti esekelwe kuBalo lwakutsha and Annual Population Survey (inkcazelo Ukongeza evela BES, YouGov uphando data ehlabathini unyulo jikelele, kwaye ulwazi vanhu vo ezininzi iqela ngalinye yonyulo nganye).
Kwiintsuku ezintathu ngaphambi kokuba kuvotwe, YouGov wabonisa okhokelayo point ezimbini Zelivu. Ngobusuku yokuvota, yokuvota wabonisa kufutshane kakhulu ukubiza (49-51 Hlalani). Lokugqibela uphando kwi-mini-kwangaphambili 48/52 baxhasa Hlala (https://yougov.co.uk/news/2016/06/23/yougov-day-poll/). Enyanisweni, oku uqikelelo uphose isiphumo sokugqibela (52-48 Ikhefu) ngamanqaku omyinge ezine.
[ , ] Bhala yokulinganisa ukubonisa nganye iimpazamo umelo kumfanekiso 3.1.
[ , ] Uphando Blumenstock noogxa (2015) ebandakanyeka ekwakheni sokufunda umatshini ungasebenzisa data wokulanda yedijithali ukuqikelela iimpendulo kuphando. Ngoku, uza kuzama into efanayo kunye dataset eyahlukileyo. Kosinski, Stillwell, and Graepel (2013) bafumanisa ukuba Facebook uthanda ulaziyo iimpawu ngamnye kunye neempawu. Okumangalisayo kukuba, ezi zinto zenzeka njani kuba oluchanileyo ngaphezu abahlobo kunye nabalingane (Youyou, Kosinski, and Stillwell 2015) .
