Yakha iisampulu zoBume beNgcaciso yeSaveyi

I-Survey yophando yophando iqala ngoCwangciso oluPhambili lweSampuli

Ehlabathini eligqibeleleyo, uphando lweprojekthi yophando lunokufunda onke amalungu ehlabathi elijoliswe kuyo. Ngokuqhelekileyo, oku akunakwenzeka kwaye akunakuhlawuleka. Kunoko, iisampuli zabantu abaninzi (iphela) zenziwe - isampula yiseko apho iingcamango zenziwa malunga nomhlaba wonke. Ukongeza, isampuli yakhiwa ngokusebenzisa ubuchule kunye nezicwangciso ezifaka isandla kwisifundo esifanelekileyo nesisisigxina.

Uphando lwemveli lweemakethi lusekelwe kwingcamango yokuba isampula - iqela elimele labaphenduli - lingabonwa kwaye lifikeleleke.

Iimviwo zeeMviwo kwiSaveyi yophando

Kuphando lweemarike, isampuli esimele sithuba sithetha ngoku:

• Ukukhethwa kwabathengi abambalwa abafanisa amalungu endalo ejoliswe kuyo yabathengi. Umzekelo wehlabathi elijoliswe kuyo lingaba ngabanikazi kunye nabasebenzisi be-SmartPhones, abaneminyaka engama-20 ukuya kuma-30.

• Umdlalo phakathi kwesampulu kunye nommandla wendalo kufuneka ube namandla kuzo zonke iimpawu ezilindeleke ukuba zibe neempembelelo kwiziphumo zophando.
  • Omnye umzekelo wesampu-kummandla wendawo yonke unokukhethwa kwabathengi beqhumiso elenziwe ngumntu omncinane, udumo lomfazi. Kulo mzekelo, iimpawu ezilindeleke ukuba zibe nefuthe kwiziphumo zophando ziya kuba yiBhinqa, iminyaka eyi-18-28 ubudala, ukuzonwabisa-savvy.
  • Isetyenti sesibini sezinto ezinokuba yiyo: Ukuhlala kweedolophu, ukubhalisa kwikholejini, ehlala kwicala elingasempuma okanye olunxweme olusentshonalanga, ingeniso yokuqonda (amanqanaba okufumana imali).

• Ubungakanani bamalungu obani na iimpawu ezifanelekileyo ezinokuthi zithathwe kwi sampulu mazingqinisise ngokulingana namalungu omhlaba wendawo ekujoliswe kuyo ngabathengi.
  • Ngokomzekelo, ukuba umboleki ummandla wabantu boshishino, abafundi beekholeji kunye nabahlali abakhulileyo, isampuli esimele singakhiwa kubafundi abavumiweyo kwisitoreji sencwadi saseyunivesithi ngoLwesithathu.
  • Ukufikelela kubathathi-nxaxheba kubunzima. Enye yezizathu eziphambili zokubangela ukuba iiphaneli zobuchwephesha zabathengi zisetyenziswe kwiimvavanyo zophando.
  • Esinye isicwangciso esiphumeleleyo kukuba kusetyenziswe inkqubo yokwenza isampula engaqhelekanga encedisa umphandi ukuba adlulise idatha malunga namaqela angaphantsi.

Ukhetho lweSample kwiSaveyi yophando

Amalungu eesampuli akhethwe ngeendlela eziliqela ezijoliswe ekunciphiseni i-bias. Kuthetha ukuba amathuba okudala izigqibo zophando ezichanekileyo zonyuka , kwaye izigqibo zingenziwa jikelele kwihlabathi elijoliswe kuyo.

Iisampuli zeSaveyi zikhethwa ngokukhethekileyo ngenkqubo yokurhweba. Ngokomzekelo, ukuba amalungu esampula akhethwe kwiziko ledatha, ngamnye umntu wesithathu kwi-list of database angakhethwa. Ngamanye amaxesha, amalungu esampula angadinga ukuba abelwe kunokuba akhethwe ngononophelo. Akuyona indlela ekhethiweyo njengoko, nangona phantsi kweemeko ezifanelekileyo, uphando luxhomekeke kwiimpawu ezingachanekanga ezisekelwe kwisampula ezinokukwenza konke ngethuba kwaye akukho nto enokuyenza ngokucwangciswa kophando. Makhe sibone uluhlu lwemithombo yephutha, luguqulelwe kwizinto zokuvota zeefowuni ezithatyathwe yiiNkxaso zoLwazi . Olu luhlu lubandakanya imithombo enokwenzeka yokungacaciswanga kuyo yonxibelelwano yophando, ukuphunyezwa kwenkqubo, kunye nokuhlalutya kwedatha yesaziso:

• Ulwazi olungapheliyo malunga namalungu egciniweyo lubangele iinguqu ezibalulekileyo ezishiywe ngaphandle kwesampuli
• Amalungu omzekelo abakhethiweyo abathandi ukungabandakanyeka kulo uphando.
• Amalungu esampulu ayanqabile ukuba bathathe inxaxheba kwisifundo ahluke ngokubhekiselele kwizinto ezibonakalayo ezibalulekileyo kwisifundo kunokuba abo basampula abavuma ukuthabatha inxaxheba.

• Abaphenduli be-Survey banikezela iimpendulo zobuxoki okanye ezingaphelelanga kwiimviwo zophando.

Izinto eziluluhlu, kwakhona ziguqulwa ukusuka kuluhlu lokuvota ngeeNkxaso zeeNzululwazi , zidibene noyilo lwenzululwazi.

• Inkqubo yokusetyenziswa kwendlela yokusetyenziswa kwamanani yayisetyenziswa kodwa-ngethuba-ithabatha amaninzi amaninzi. ^*
• Imibuzo ephandululweyo ayilwa kakuhle kwaye idibanisa abaphenduliweyo.
• Umyalelo wemibuzo kwiphononongo ithonya kakhulu iimpendulo zemibuzo elandelayo.
• Iimpendulo zeSaveyi zixhomekeke kwi-weighting okanye iqela eliphazamisa idatha.

Xa umphandi weemarike ekhululekile ngokufanelekileyo ukuba isampula imela abantu abajoliswe kulo kuphando lwakhe, uphando luya kutshintsha ukujonga ubungakanani besampula kunye nexesha lokuzithemba .

Izixhobo zoVavanyo yiwebhusayithi echaphazelekayo eyenziwe ngabaphandi bezesayikethi abazama ukubala ukubala nokukhupha ngaphandle.
