2.5 Kutsiliza
deta Big zili paliponse, koma ntchito ndi zina deta taona kufufuza chikhalidwe ndi zovuta. Mu zimene ndinaona pali chinachake ngati palibe ufulu nkhomaliro katundu kufufuza ngati mulibe anaika kwambiri ntchito deta, ndiye kuti mwina titi anaika kwambiri ntchito kusanthula deta yanu kapena kuganizira zimene zili funso chidwi kufunsa za deta. Zochokera maganizo m'mutu uno, ine ndikuganiza kuti pali njira zitatu zikuluzikulu zimene magwero aakulu deta adzakhala lofunika kwambiri kufufuza okhudzidwa:
- empirically adjudicating pakati kupikisana maulosi ongolankhula. Zitsanzo za ntchito imeneyi monga Farber (2015) (New York Taxi madalaivala) ndi King, Pan, and Roberts (2013) (kufufuza mu China)
- bwino muyeso nawo pa ndondomeko kudzera nowcasting. Chitsanzo cha ntchito imeneyi ndi Ginsberg et al. (2009) (Google Matenda a Chimfine Trends).
- kuyerekeza zotsatira causal ndi zatsopano zachilengedwe ndi yofananira. Zitsanzo za ntchito imeneyi. Mas and Moretti (2009) (kusuzumiramo mmene zokolola) ndi Einav et al. (2015) (zotsatira za mtengo poyambira pa amagulitsa nsombazo pa eBay).
mafunso zambiri zofunika kafukufuku chikhalidwe kungasonyezedwe monga mmodzi wa awa atatu. Komabe, njira imeneyi kumafuna ofufuza kubweretsa kwambiri kwa deta. N'chiyani chimachititsa Farber (2015) chidwi ndi zolinga ongolankhula choyezera lapansi. Izi zolinga ongolankhula zichokera kunja kwa deta. Choncho, anthu amene ali bwino kufunsa mitundu ina ya mafunso kafukufuku, magwero aakulu deta kungakhale kuberekana.
Pomaliza, osati chiphunzitso lotengeka kafukufuku wazotsatira (amene akhala akupereka maganizo pa mutu uwu), tikhoza tayizunguzani ndi script ndi kulenga empirically lotengeka kalelo. Amene, mwa kudzikundikira mosamala mfundo wazotsatira, moyo, ndi masamu, tingalimbitse ziphunzitso zatsopano.
Izi njira, data-poyamba njira kuti chiphunzitso si chatsopano, ndipo mwamphamvu linanena ndi Glaser and Strauss (1967) ndi kuitana kwawo kwa chiphunzitso chinakhazikika. Njira imeneyi data-choyamba Komabe, sizikutanthauza "mapeto a chiphunzitso," monga akuti ndi yaikulu ya utolankhani padziko kafukufuku mu m'badwo digito (Anderson 2008) . M'malo mwake, monga kusintha malo deta, tiyenera kuyembekezera kukonzanso zinatanthauza ubale wa pakati pa chiphunzitso ndi deta. M'dziko limene zosonkhanitsira deta zinali zofuna ndalama zambiri, ndi bwino kokha kusonkhanitsa deta kuti mfundo amati adzakhala zothandiza kwambiri. Koma, mu dziko kumene ndalama yaikulu kwambiri deta kale kupezeka kwa free, ndi bwino kuyesetsa ndi data-poyamba njira (Goldberg 2015) .
Monga Ine asonyeza mu chaputala ichi, ofufuza angaphunzire zambiri mwa kuona anthu. Yotsatira machaputala atatu, ine mmene tingaphunzire zinthu zambiri ndi osiyana ngati ife kukonza kusonkhanitsa wathu deta ndi kucheza ndi anthu mwachindunji powafunsa mafunso (Chapter 3), kuthamanga zatsopano (Chapter 4), ndipo ngakhalenso iwo m'kati kafukufuku mwachindunji (Chapter 5).
