Izindlela Zocwaningo Lwezomnotho
Izindlela zocwaningo lwezomnotho ziyiqoqo lamasu nezinqubo ezisetshenziswa osomnotho nabacwaningi ukuqonda, ukuhlaziya, nokubikezela izenzakalo zomnotho. Ucwaningo lwezomnotho ludlala indima ebalulekile ekuthuthukisweni kwethiyori yezomnotho, inqubomgomo, kanye nokusebenza. Lesi sihloko sizoxoxa ngezindlela ezahlukene zocwaningo lwezomnotho, okuhlanganisa izindlela zokuhlola kanye nezibalo, kanye namasu okuqoqwa kwedatha kanye nokuhlaziya asetshenziswa kakhulu ezifundweni zomnotho.
Indlela Yokulinganisa
Indlela yokulinganisa ucwaningo lwezomnotho ihilela ukuqoqa nokuhlaziya idatha yezinombolo ukuze kutholakale amaphethini, ubudlelwano, noma izitayela. Le ndlela ivame ukubhekwa njengengakhethi ngoba imiphumela ingalinganiswa futhi ihlaziywe kusetshenziswa amathuluzi ezibalo.
1. Ukuhlolwa kanye nokuhlolwa okungamanga
Ukuhlolwa kuyindlela yokucwaninga ehilela ukuphatha iziguquguquko ezizimele ezilodwa noma ngaphezulu nokubuka imiphumela yazo kuguquko oluxhomekekile. Ukuhlolwa kuvame ukwenziwa elabhorethri noma kwenye indawo elawulwa ngokuqinile. Kodwa-ke, ngenxa yokuthi kunzima ukukusebenzisa ezimweni zomnotho, lapho ukungenelela okuqondile kuvame ukungabi nasimilo noma okungasebenzi, ukuhlolwa mbumbulu noma ukuhlolwa kwemvelo kuvame ukusetshenziswa. Ukuhlolwa kwemvelo kusebenzisa izehlakalo ezenzeka ngokwemvelo "njengezivivinyo" zokubuka imiphumela yazo.
2. Ukuhlola kanye Nemibuzo
Ucwaningo kanye nemibuzo kuyizindlela ezivamile zokuqoqa idatha yobuningi ocwaningweni lwezomnotho. Ucwaningo lungenziwa mathupha, ngocingo, noma ku-inthanethi. Lungahlanganisa izihloko ezahlukahlukene, kusukela ekusweleni umsebenzi kanye nemali engenayo yemindeni kuya emibonweni yabathengi. Abacwaningi basebenzisa ucwaningo ukuqoqa idatha kumasampula amakhulu nokuhlanganisa okutholakele kubantu abaningi.
3. Ukuhlaziywa Kwezibalo Nokwezomnotho
Ukuhlaziywa kwezibalo kuhilela ukusebenzisa amathuluzi ezibalo ukuhlaziya idatha nokuhlonza amaphethini noma ubudlelwano. I-Econometrics iyigatsha elikhethekile lezibalo eligxile ekusetshenzisweni kwezindlela zezibalo kudatha yezomnotho. Lobu buchwepheshe busebenzisa amamodeli ezibalo kanye nokubuyela emuva okuqondile ukubikezela izinguquko zomnotho nokuhlola imibono yezomnotho. Besebenzisa izazi zezomnotho, izazi zezomnotho zingalinganisa isidingo semakethe, zihlaziye imiphumela yezinqubomgomo zomnotho, futhi zibikezele ukukhula komnotho.
4. Ukuhlaziywa Kokufaka Nokukhipha
Ukuhlaziywa kokufakwayo nokukhishwayo kuyindlela yokulinganisa esetshenziswa ukuhlola ubudlelwano phakathi kwemikhakha ehlukene yezomnotho. Yasungulwa nguWassily Leontief, le ndlela ihilela i-matrix ekhombisa indlela umkhiqizo wemboni eyodwa osetshenziswa ngayo njengokufakwayo komunye umkhakha. Lokhu kusiza ukuqonda isakhiwo somnotho kanye nomthelela wezinguquko ekukhiqizeni komunye umkhakha kweminye.
Indlela Esezingeni Elifanele
Izindlela zokucwaninga kwezomnotho ezisezingeni eliphezulu zihilela ukuqoqa idatha engeyona eyezinombolo ukuze kuqondwe ngokujulile izimo zomnotho kanye nokuziphatha kwabantu. Le ndlela ithinta kakhulu imizwa yabo kodwa inikeza ukuqonda okuningiliziwe komongo okungenakufezwa ngezindlela zokulinganisa zodwa.
1. Ucwaningo Lwecala
Ucwaningo lwecala luyindlela yokuqoqwa kwedatha esezingeni eliphezulu lapho abacwaningi benza khona ukuhlaziywa okujulile kwecala elilodwa noma amacala amaningana ngaphakathi komongo wangempela. Lezi zifundo ziwusizo kakhulu ekuqondeni ukuguquguquka okuyinkimbinkimbi ngaphakathi komongo othize. Isibonelo, ucwaningo lwezinqubomgomo zomnotho zezwe lungaveza imiphumela ethile yezenhlalo nezomnotho kanye nezinselele ezibhekene nazo.
2. Ingxoxo Ejulile
Izingxoxo ezijulile zihilela ukuxhumana okuqondile phakathi kwabacwaningi nabaphenduli. Ngalezi zingxoxo, abacwaningi baqoqa idatha esezingeni eliphezulu ngokusekelwe kokuhlangenwe nakho kwabaphenduli, imibono, kanye nemibono yabo. Le ndlela iwusizo kakhulu ekutholeni ukuqonda okucebile nokujulile kwezinkinga zomnotho eziyinkimbinkimbi. Izingxoxo ezijulile zingahlelwa, zingahlelwanga kahle, noma zingahlelwanga kahle.
3. Iqembu Lokugxila
Iqembu lokugxila liyindlela esezingeni eliphezulu lapho kukhethwa khona iqembu elincane labantu ukuze lixoxe ngesihloko noma udaba oluthile. Umholi wengxoxo uqondisa ingxoxo futhi aqophe imibono emisha. Le ndlela iphumelela kakhulu ekuhloleni imibono ehlangene kanye nemibono yesimo sezomnotho.
4. Ukubuka Okuqondile
Ukubuka okuqondile kuyindlela yokuqoqa idatha lapho abacwaningi bebuka khona abantu endaweni yabo yemvelo ngaphandle kokungenelela. Lokhu kubuka kungaba ukuhlanganyela noma ukungabi yingxenye. Le ndlela inikeza ukuqonda ngokuziphatha kwezomnotho esimweni sayo semvelo, njengokuthi abathengi benza kanjani izinqumo zokuthenga emakethe noma ukuthi abasebenzi basebenzisana kanjani endaweni yokusebenza.
Ukuhlanganiswa Kwezindlela Zokulinganisa Nokulinganisa
Ucwaningo oluphelele lwezomnotho luvame ukudinga ukuhlanganiswa kwezindlela zokulinganisa kanye nezindlela zokuhlola. Indlela yezindlela ezixubile ivumela abacwaningi ukuthi basebenzise amandla azo zombili izindlela futhi babhekane nobuthakathaka bazo ngazinye. Isibonelo, abacwaningi bangasebenzisa izinhlolovo zokulinganisa ukuze bathole izindlela ezijwayelekile, kulandelwe izingxoxo ezijulile ukuze baqonde umongo kanye nezizathu zalezo zindlela.
Indlela yokuqoqwa kwedatha
1. Idatha Eyinhloko
Idatha eyinhloko idatha eqoqwe ngqo ngabacwaningi ngezinjongo ezithile zocwaningo. Lezi zindlela zifaka phakathi izinhlolovo, izingxoxo, ukuqaphela, kanye nokuhlolwa. Ukuqoqa idatha eyinhloko kuvumela abacwaningi ukulawula inqubo yokuqoqwa kwedatha nokuqinisekisa ukubaluleka nokuthembeka kolwazi oluqoqwe.
2. Idatha Yesibili
Idatha yesibili idatha eqoqwe ngaphambilini yinye inhlangano futhi iyatholakala ukuthi abacwaningi bayisebenzise. Imithombo yedatha yesibili ifaka phakathi izincwadi zikahulumeni, imibiko yenkampani, omagazini bezemfundo, kanye nezizindalwazi zezibalo. Nakuba kufinyeleleka kalula kunedatha eyinhloko, idatha yesibili ingase ingahlangabezani ngokugcwele nezidingo zocwaningo ngenxa yezinhloso ezahlukene eziqoqwe ngazo.
Ukuhlaziywa kwedatha
Ngemva kokuqoqwa kwedatha, isinyathelo esilandelayo ukuhlaziywa kwedatha. Ocwaningweni lwezibalo, ukuhlaziywa kwedatha kuvame ukuhilela ukusebenzisa isofthiwe yezibalo njenge-SPSS, i-SAS, i-Stata, noma i-R ukwenza izivivinyo zezibalo kanye namamodeli ezomnotho. Ukuhlaziywa kwedatha yekhwalithi, okwamanje, kuvame ukuhilela ukufaka ikhodi ukuze kutholakale izindikimba namaphethini ngaphakathi kwedatha. Isofthiwe efana ne-NVivo noma i-Atlas.ti ivame ukusetshenziselwa ukusiza ekuhlaziyweni kwedatha yekhwalithi.
Isiphetho
Izindlela zocwaningo lwezomnotho zingamathuluzi abalulekile asetshenziswa osomnotho nabacwaningi ukuhlola, ukuqonda, nokubikezela izenzakalo zomnotho. Ngokusebenzisa izindlela ezahlukene namasu—kokubili okubala kanye nokwekhwalithi—abacwaningi bangathola ukuqonda okuphelele ngezinkinga zomnotho. Ukuhlanganisa lezi zindlela kunganikeza umbono ophelele nojulile, kusize ekuthuthukisweni kwezinqubomgomo nemikhuba yezomnotho esebenza kahle kakhulu. Ukuqonda nokusebenzisa izindlela zocwaningo ezifanele kubalulekile ekufinyeleleni imiphumela yocwaningo evumelekile, ethembekile, newusizo.
