   2. Bapisa le ho bapisa liphetho tsa hau le tse tsoang ho phuputso ea Mechanical Turk e Goel, Obeng, and Rothschild (2016) .

4. [ ,, ,, ] Liphuputso tse ngata li sebelisa mehato ea boipheliso ea ho sebelisa liselefouno. Ena ke boemo bo thahasellisang boo bafuputsi ba ka bapisang boitsoaro ba boits'oaro ka boitšoaro bo hlephileng (bona mohlala, Boase and Ling (2013) ). Mekhoa e 'meli e tloaelehileng eo motho a ka e botsang ka eona ke ea ho letsetsa le ho romellana melaetsa,' me liforeimi tse peli tse tloaelehileng ke "maobane" le "bekeng e fetileng."

   2. Batla metsoalle ea hau e mehlano hore e be lipatlisisong tsa hau. Ka kopo, akaretsa ka bokhutšoanyane hore na metsoalle ena e mehlano e ne e nkiloe joang. Na ts'ebetso ee ea sampling e ka etsa hore ho be le likhetho tse itseng ka tekanyo ea hau?
   3. Ba botse lipotso tse latelang tsa microsurvey:
   • "Ke makhetlo a mangata ao u sebelitseng thelefono ea hau ea selefouno ho bitsa ba bang maobane?"
   • "U rometse melaetsa e mengata ea melaetsa maobane?"

   • "Ke makhetlo a mangata ao u sebelitseng mohala oa hao oa selefouno ho romela kapa ho amohela melaetsa ea selefouno / SMS matsatsing a supileng a ho qetela?"
   4. Hang ha sena sa microsurvey se phethiloe, botsa ho hlahloba boitsebiso ba bona ba ho sebelisa ha ba ntse ba kena ka fono kapa mofani oa bona oa tšebeletso. Tlhaloso ea ho ipapisa le ea hau e bapisoa joang le ho ngolisa lintlha? Ke efe e nepahetseng ka ho fetisisa, e nepahetseng haholo?
   5. Hona joale kopanya lintlha tseo u li bokeletseng le lintlha tse tsoang ho batho ba bang sehlopheng sa hau (haeba u etsa mosebetsi ona bakeng sa tlelase). Ka dataset ena e kholo, pheta karolo (d).

5. [ ,, ] Schuman and Presser (1996) re lipotso tsa lipotso li tla ba le lipotso tsa mefuta e 'meli ea lipotso: lipotso tse arolelanoang lipotso moo lipotso tse peli li leng boemong bo ts'oanang (mohlala, litekanyetso tsa batlatsi ba babeli ba mopresidente); le karolo e 'ngoe-lipotso moo potso e tloaelehileng e latelang potso e tobileng (mohlala, ho botsa "U khotsofetse hakae ka mosebetsi oa hau?" o lateloa ke "U khotsofetse hakae ka bophelo ba hau?").

   Ba tsoela pele ho hlalosa mefuta e 'meli ea potso ea lipotso: liphello tse tsitsitseng li etsahala ha likarabo tsa potso e tlang li ntse li atamela (ho feta kamoo li neng li tla ba kateng) ho ba fuoeng potso ea pele; phapang e fapaneng e etsahala ha ho e-na le phapang e kholo pakeng tsa likarabo tse peli.

Etsa tlhahlobo ea lipatlisiso Turkong ea Amazon Mechanical ho leka lipotso tsa hau.
      
   2. U khonne ho bopa karolo e kholo ea karolo e kae? E ne e le ts'ebetso e tsitsitseng kapa e fapaneng?
   3. U na le phello e kholo hakae-eo u khonang ho e etsa? E ne e le ts'ebetso e tsitsitseng kapa e fapaneng?

6. [ ,, ] Ho haha ​​mosebetsing oa Schuman and Presser, Moore (2002) hlalosa phapang e fapaneng ea pheliso ea lipotso: liphetoho tse eketsang le tse senyang. Le hoja liphetoho le liphello tse tsitsitseng li hlahisoa ka lebaka la ho hlahlojoa ha lintho tseo tse peli tse amanang le tsona, liphello tse tlatsehang le tse senyang li hlahisoa ha ba arabelitsoeng ba etsoa ka hloko haholoanyane moralo o moholoanyane oo lipotso li botsitsoeng ho tsona. Bala Moore (2002) , ebe o qapa le ho etsa lipatlisiso ho MTurk ho bonahatsa liphello tse eketsang kapa tse tlohang.

7.

8. [ ] Ka boiteko ba ho bolela esale pele liphello tsa EU ea 2016 Referendum (ke hore, Brexit), YouGov-e leng marang-rang a ho etsa lipatlisiso tsa 'maraka-a tsamaisoang marang-rang a sehlopha sa batho ba ka bang 800 000 ba arabelitsoeng United Kingdom.

   Tlhaloso e qaqileng ea sebopeho sa lipalo tsa YouGov se ka fumanoa ho https://yougov.co.uk/news/2016/06/21/yougov-referendum-model/. UGov o ile a arola likhetho ka mefuta e thehiloeng ho khetho ea likhetho ka kakaretso ea likhetho tsa 2015, lilemo, litšoaneleho, tekano le letsatsi la lipuisano, hammoho le sebaka seo ba neng ba lula ho sona.

Tlhahlobo ea ho qetela ea letsatsi e boletse hore 48/52 e le ho rata ho lula (https://yougov.co.uk/news/2016/06/23/yougov-day-poll/). Ha e le hantle, tekanyetso ena e hlokometse phello ea ho qetela (Lekhetlo la 52/48) ka lintlha tse 'nè tsa palo.

   1. Sebelisa moralo oa phoso oa lipatlisiso o tšohloang khaolong ena ho hlahloba hore na ho ka etsahala'ng.
   2. Karabo ea UGov ka mor'a likhetho (https://yougov.co.uk/news/2016/06/24/brexit-follows-close-run-campaign/) e hlalositse: "Sena se bonahala se le karolo e kholo ka lebaka la ho etela-ntho e ' re boletse hore nako eohle e tla ba ea bohlokoa bakeng sa phello ea morabe o joalo o loketseng.
