  1. [ zovuta , imakhala masamu ] Mutu uno, ndinali wokondwa kwambiri ponena za stratification. Komabe, izi sizikuthandizira nthawi zonse kuchuluka kwa chiwerengero. Pangani mkhalidwe pamene chitsimikizo chitha kuchepetsa ubwino wa mawerengedwe. (Kuti mumvetse, onani Thomsen (1973) .)

  2. [ zovuta , kusonkhanitsa deta , imayenera kuwerengera ] Kulinganiza ndi kuyendetsa kafukufuku wa Amazon Mechanical Turk omwe sitingathe kufunsa kuti afunse za umwini wa mfuti ndi momwe amaonera kuyendetsa mfuti. Kuti muthe kuyerekezera malingaliro anu kwa omwe achokera ku chithunzi chotheka, chonde lembani mafunso ndi mayankho omwe mwasankha kuchokera ku kafukufuku wapamwamba monga omwe akuyendetsa Pew Research Center.

    1. Kodi kufufuza kwanu kwatenga nthawi yayitali bwanji? Amagulitsa bwanji? Kodi chiwerengero cha anthu omwe mumayesera chikufanizira ndi chiwerengero cha anthu a US?
    2. Kodi kulingalira kwakukulu kwa umwini wa mfuti pogwiritsa ntchito chitsanzo chanu?
    3. Lembani zosayimilira za chitsanzo chanu pogwiritsira ntchito stratification kapena njira ina. Tsopano kodi chiwerengero cha umwini wa mfuti ndi chiyani?
    4. Kodi ndondomeko yanu ikuyerekeza bwanji ndi chiwerengero chaposachedwa kuchokera ku zitsanzo zotheka? Mukuganiza kuti mukufotokozera chiyani zotsutsana, ngati zilipo?
    5. Bweretsani mafunso (b) - (d) chifukwa cha maganizo okhudza kuwombera mfuti. Kodi zomwe mukupeza zikusiyana bwanji?

  3. [ zovuta kwambiri , kusonkhanitsa deta , imayenera kuwerengera ] Goel ndi anzake (2016) adayankha mafunso okwana 49 omwe amachokera ku General Social Survey (GSS) ndikusankha kafukufuku ndi Pew Research Center kwa anthu omwe sankakhala nawo mwayi wochokera ku Amazon Mechanical Turk. Kenaka adasintha zosiyana siyana za deta pogwiritsira ntchito chitsanzo cha ma stratification ndi kuyerekeza kulingalira kwawo kosinthika ndi omwe akuchokera ku kafukufuku wa GSS ndi Pew. Pezani kafukufuku womwewo pa Amazon Mechanical Turk ndipo yesetsani kufotokozera chifaniziro cha 2a ndi chifaniziro 2b poyerekeza chiwerengero chanu chosinthidwa ndi chiwerengero cha zochitika zaposachedwapa za GSS ndi Pew kafukufuku. (Onani ndondomeko yowonjezera A2 pandandanda wa mafunso 49.)

    1. Yerekezerani ndikusiyanitsa zotsatira zanu ndi anthu a Pew ndi GSS.
    2. Yerekezerani ndi kuyerekezera zotsatira zanu ndi zomwe zafukufuku wa Mechanical Turk ku Goel, Obeng, and Rothschild (2016) .

  4. [ zamkati , kusonkhanitsa deta , imayenera kuwerengera ] Kafukufuku wambiri amagwiritsa ntchito njira zowonetsera mafoni. Izi ndi zochititsa chidwi zomwe ochita kafukufuku amatha kudziyerekezera ndi khalidwe lawo lokhazikika (onani mwachitsanzo, Boase and Ling (2013) ). Zizolowezi ziwiri zomwe anthu ambiri amafunsa zokhudza kuitana ndi kulemberana mameseji, ndipo mafelemu awiri omwe amakhala nawo nthawi zonse ndi "dzulo" komanso "sabata lapitalo."

    1. Musanayambe kusonkhanitsa deta iliyonse, ndi yani yotsimikiziranso zomwe mukuganiza kuti ndi yolondola? Chifukwa chiyani?
    2. Pemphani anzanu asanu kuti akhale mufukufuku wanu. Chonde mwachidule kufotokoza mwachidule momwe anzako asanu adasankhidwira. Kodi njirayi yotsatilazi ingapangitse zosokoneza zomwe mumaganiza?
    3. Afunseni mafunso otsatirawa:
    • "Ndi kangati yomwe wagwiritsa ntchito foni yako kuti uitane ena dzulo?"
    • "Mumatumizira mauthenga angati dzulo?"
    • "Ndi kangati yomwe wagwiritsa ntchito foni yako kuti uitane ena masiku asanu ndi awiri apitawo?"
    • "Ndi kangati yomwe wagwiritsa ntchito foni yako kutumiza kapena kulandira mameseji / ma SMS m'masiku asanu ndi awiri apitawo?"
    1. Pamene microsurvey iyi yatsirizika, funsani kuti muwone deta yawo yogwiritsira ntchito poyendetsedwa ndi foni kapena wothandizira. Kodi kudzigwiritsira ntchito kotani kumalingani ndi deta lolemba? Kodi ndi yolondola kwambiri, yomwe ndi yolondola kwambiri?
    2. Tsopano phatikizani deta yomwe mwasonkhanitsa ndi deta kuchokera kwa anthu ena mukalasi lanu (ngati mukuchita ntchitoyi kwa kalasi). Ndi deta yaikulu iyi, bweretsani mbali (d).

  5. [ zamkati , kusonkhanitsa deta ] Schuman and Presser (1996) amatsutsana ndi mafunso omwewa ndi ofunika mafunso awiri: mafunso okhudzana ndi magawo awiri omwe ali ndi chiwerengero chofanana (mwachitsanzo, mayeso a azimayi awiri); ndi mafunso ena onse omwe funsoli likutsatira funso lodziwika bwino (mwachitsanzo, kufunsa "Kodi muli okhutira bwanji ndi ntchito yanu?" kenako "Ndinakhutitsidwa bwanji ndi moyo wanu?").

    Amapitiriza kufotokoza mitundu iwiri ya kusintha kwa funso: zotsatira zofanana zimapezeka pamene mayankho a funso lotsatira amabweretsa pafupi (kuposa momwe angakhalire) kwa iwo omwe aperekedwa ku funso lakale; Kusiyanasiyana kumachitika pamene pali kusiyana kwakukulu pakati pa mayankho ku mafunso awiri.

    1. Pangani awiri a magawo a gawo lomwe mukuganiza kuti adzakhala ndi zotsatira zowonjezera mafunso; magawo awiri-mafunso onse omwe mukuganiza kuti adzakhala ndi zotsatira zazikulu; ndi mafunso awiri omwe mukuganiza kuti palibe kanthu. Fufuzani kafukufuku pa Amazon Mechanical Turk kuti muyese mafunso anu.
    2. Kodi ndi gawo lanji lalikulu lomwe mudatha kulenga? Kodi zinali zosagwirizana kapena zosiyana zosiyana?
    3. Kodi ndi zotsatira zazikulu bwanji zomwe mwatha kupanga? Kodi zinali zosagwirizana kapena zosiyana zosiyana?
    4. Kodi pangakhale kusintha kwa mafunso pakati pa awiriwa pomwe simunaganize kuti dongosololo likhale lofunika?

  6. [ zamkati , kusonkhanitsa deta ] Kuwonjezera pa ntchito ya Schuman and Presser, Moore (2002) akufotokoza mbali yosiyana ya zotsatira zoyendera mafunso: zotsatira zowonjezera ndi zochotsa. Ngakhale kuti zosiyana ndi zotsatira zake zimagwiritsidwa ntchito monga zotsatira za anthu omwe amafunsidwa pazochitika ziwirizo poyenderana wina ndi mzake, zotsatira zowonjezera ndi zowonongeka zimaperekedwa pamene ofunsidwa amavomereza kwambiri chikhazikitso chachikulu chomwe mafunsowo akufunsidwa. Werengani Moore (2002) , ndikukonzekera ndikuyesa kufufuza pa MTurk kuti muwonetse zotsatira zowonjezera kapena zochotsera.

  7. [ zovuta , kusonkhanitsa deta ] Christopher Antoun ndi anzake ogwira nawo ntchito (2015) adapanga kafukufuku poyerekeza ndi zopezeka pazinthu zinayi zochokera ku intaneti: MTURK, Craigslist, Google AdWords ndi Facebook. Pangani kafukufuku wosavuta ndi kuitanitsa ophunzira kudzera m'mabuku awiri othawiramo ntchito pa Intaneti (magwerowa akhoza kukhala osiyana ndi magwero anayi ogwiritsidwa ntchito ku Antoun et al. (2015) ).

    1. Yerekezerani mtengo wogwiritsira ntchito-mwa ndalama ndi nthawi pakati pa magulu osiyanasiyana.
    2. Yerekezerani momwe mukugwiritsira ntchito zitsanzo zomwe zatengedwa kuchokera kuzinthu zosiyanasiyana.
    3. Yerekezerani ndi khalidwe la deta pakati pa zitsanzo. Malingaliro okhudza momwe mungayezere khalidwe la deta kwa ofunsidwa, onani Schober et al. (2015) .
    4. Kodi gwero lanu lopindulitsa ndi lotani? Chifukwa chiyani?

  8. [ zamkati ] Poyesera kufotokozera zotsatira za 2016 EU Operendum (ie, Brexit), YouGov-yofufuza pamsika wofufuza msika-yomwe inachitidwa pa intaneti pa gulu la anthu okwana 800,000 omwe anafunsidwa ku United Kingdom.

    Kufotokozera tsatanetsatane wa chitsanzo cha YouGov yazomwekupezeka kungapezeke pa https://yougov.co.uk/news/2016/06/21/yougov-referendum-model/. Mwachidule, YouGov adagawila voti m'mitundu yotsatizana ndi chisankho chokhala ndi chisankho chakale cha 2015, zaka, ziyeneretso, ubwino, ndi tsiku lofunsidwa, komanso malo omwe adakhalamo. Choyamba, iwo adagwiritsa ntchito deta yomwe inasonkhanitsidwa kuchokera kwa InuGov panelists kuti muyese, pakati pa omwe adasankha, chiwerengero cha anthu a mtundu uliwonse wa voti omwe akufuna kuti asankhe. Amaganiza kuti kusintha kwa mtundu uliwonse wa voti pogwiritsa ntchito Bungwe la Bungwe la British Electoral Study (BES) la 2015, posankha chisankho choyang'ana pamasom'pamaso, chomwe chinatsimikiziranso kuchoka pamabwalo a chisankho. Potsirizira pake, iwo amawonetsa kuti ndi anthu angati omwe alipo pa mtundu uliwonse wa voti mu chisankho, kuchokera pa kafukufuku wam'mbuyomu ndi kafukufuku wa pachaka (ndi zina zowonjezeredwa kuchokera kuzinthu zina za deta).

    Masiku atatu asanavotere, YouGov adawonetsa chitukuko cha mfundo ziwiri kuti achoke. Usiku watatsala pang'ono kuvota, kafukufukuyo wasonyeza kuti zotsatira zake zinali pafupi kwambiri kuti asaitanidwe (49/51 Khalani). Kufufuza komaliza pa tsiku kunaneneratu 48/52 kuti mukhalebebe (https://yougov.co.uk/news/2016/06/23/yougov-day-poll/). Ndipotu, kuyerekezera uku kunasowa zotsatira zomaliza (kuchoka kwa 52/48) ndi mfundo zinayi.

    1. Gwiritsani ntchito ndondomeko yowonongeka yofufuza yomwe ikufotokozedwa mu chaputala chino kuti muone zomwe zakhala zikulakwika.
    2. Mayankho a YouGov pambuyo pa chisankho (https://yougov.co.uk/news/2016/06/24/brexit-follows-close-run-campaign/) anafotokoza kuti: "Izi zimawoneka mbali yaikulu chifukwa cha kutembenuka-chinachake chomwe tanena kuti nthawi zonse zidzakhala zofunikira kwambiri pamapeto a mpikisano woterewu. Chitsanzo chathu chotsatira chinakhazikitsidwa, pokhapokha, ngati ovomera atavota pa chisankho chachikulu chotsiriza ndipo pangakhale chisankho choposa momwe chisankho chimawonongera chitsanzo, makamaka kumpoto. "Kodi izi zikusintha yankho lanu ku gawo (a)?

  9. [ zamkati , imayenera kuwerengera ] Lembani mawu oyimira kuti muwonetsetse zolakwika zonse zomwe zikuimira pa chithunzi 3.2.

    2. Pangani vuto pamene zolakwitsa zikuphatikizana.

  10. [ zovuta kwambiri , imayenera kuwerengera ] Kafukufuku wa Blumenstock ndi anzako (2015) akuphatikizapo kupanga makina ophunzirira makina omwe angagwiritse ntchito deta yolongosola ndondomeko kuti awonere mayankho a kafukufuku. Tsopano, muyesa chinthu chomwecho ndi dataset yosiyana. Kosinski, Stillwell, and Graepel (2013) adapeza kuti Facebook amakonda zimalongosola makhalidwe ndi makhalidwe. N'zosadabwitsa kuti maulosi awa akhoza kukhala olondola kwambiri kuposa anzanu ndi anzanu (Youyou, Kosinski, and Stillwell 2015) .

    1. Werengani Kosinski, Stillwell, and Graepel (2013) , Kosinski, Stillwell, and Graepel (2013) fanizo 2. Deta yawo ilipo pa http://mypersonality.org/
    2. Tsopano, pempherani fanizo lachitatu.
    3. Pomaliza, yesetsani chitsanzo chanu pa Facebook: http://applymagicsauce.com/. Zimakulimbikitsani bwanji?

  11. [ zamkati ] Toole et al. (2015) adagwiritsa ntchito mauthenga ofotokozera ma CD (CDRs) kuchokera pa mafoni kuti afotokoze za ntchito zosagwira ntchito.

    1. Yerekezerani ndi kuyerekezera zojambula za Toole et al. (2015) ndi Blumenstock, Cadamuro, and On (2015) .
    2. Kodi mukuganiza kuti CDRs iyenera kuyimitsa kafukufuku wamakono, kuwathandizira kapena kusagwiritsidwa ntchito konse kwa olemba ndondomeko kuti ayang'anire ntchito? Chifukwa chiyani?
    3. Kodi ndi umboni wotani umene ungakutsutseni kuti CDRs ingathe kusintha m'malo mwa chikhalidwe cha umphawi?
