Nobudlelwane kunye analysis parameter nganye kunye nesicelo yayo ngokubanzi kuqoqosho

liye lasetyenziswa iindlela Basic manani kuzo zonke iinkalo zezinto ezenziwa luluntu. Nangona kunjalo, indima ebalulekileyo eyadlalwa manani kuqoqosho. Ngapha koko, eli sebe inzululwazi elawula ubudlelwane yezentlalo noqoqosho zamaziko zoshishino inxaxheba kuhlalutyo kunye nokusebenza omkhulu izixa zolwazi.

Amaxesha amaninzi izifundo zoqoqosho ukufumana isisombululo kwingxaki ekuchongeni iinkalo ukuqinisekisa inqanaba inkqubo neentshukumo kuqoqosho. Loo ngxaki idla elisombulula uhlalutyo ukuhlanganisa ukuqhubeka kwaba bafundi. Ukuze kufikelelwe ukuthembeka zohlalutyo kuyimfuneko nje kuphela ukuchonga unxulumano ezithile, kodwa kwakhona ubungakanani ezi mpawu.

Nobudlelwane kunye analysis Isemantiki uyayisombulula le ngxaki, njengovavanyo lwe hypothesis-manani malunga ubukho kunye namandla nobudlelwane. inani elaneleyo kwizinto ezichaphazela inkqubo uqoqosho, kodwa variables random. Le nto isebenza kunikezo ekuhlalutyeni loqoqosho izenzakalo nomba ubudlelwane phakathi amaxabiso random and non-ejikelezayo. Ezi zonxibelelwano ibizwa ngokuba ukuhlehla kwaye ngoko ke indlela statistical, leyo izifundo kuzo - uhlalutyo ukuqhubeka kwaba bafundi.

Ngenxa uphuhliso oluqhubekayo zobugcisa computer, ukusetyenziswa kobugcisa computer liya kusetyenziswa izibalo zamanani. Ngaloo ndlela, ukusetyenziswa software lweenkcukacha-manani ezithile kwikhompyutha ikuvumela ukuba ukusombulula ngokukhawuleza iingxaki ulwalamano yemida eyahlukeneyo esebenzisa uhlalutyo ukuqhubeka kwaba bafundi.

Ngoko ke, nobudlelwane kunye nocazululo parameter nganye (umzekelo a) ibonisa ngokwaneleyo ukusetyenziswa kwayo kunye nenkqubo Microsoft Excel xa ukwinkqubo amazinga otshintshiselwano data.

Microsoft Excel I-toolkit ikuvumela ukuba ukusombulula iingxaki ezintsonkothileyo manani kunye nobunjineli usebenzisa iseti ezizodwa izixhobo analysis data. Nobudlelwane kunye analysis ukuhlehla Excel lwenziwa kunye ebonisa imbopheleleko lwe data kwaye ukhetho kokuqala iparameters. Uhlalutyo ngokwayo ungenziwa kusetyenziswa ezikulu-manani (kwakhona umsebenzi ezikhoyo zobunjineli), isiphumo ifakwa kuluhlu akhutshwayo lingakhankanywa ngumsebenzisi. Ukuba usebenzisa ezinye iindlela zenkqubo, singakwazi ukufumana isiphumo ngohlobo lomzobo.

Ngoncedo lwe umfanekiso umhlalutyi graphic ungabona lumelo olubonakalayo kwedatha yeenkcukacha-manani. Le imo kube lula kakhulu imbono kunye nokuqonda kweziphumo.

Ngokomzekelo, xa kuxutywa amanani itafile ngamanye amaxesha kunzima ukubona iimpazamo okanye engachananga. Ukumelwa njenge igrafu data ikuvumela ukuba ngokukhawuleza nangokulula ukubona ezinxaxhileyo kunye mgaqweni, ukunyuka ezibukhali okanye idrophu data, nangona itafile akuthethi zinto zingumqondiso izinto ezimbi kangaka.

Ukuhlanganisa yeyona Microsoft Excel isixhobo package. Ingasetyenziswa ukwenza ubungakanani ubudlelwane iiseti data eziliqela. Uhlalutyo unxulumano na ukuseka ubudlelwane xa ubukhulu iiseti data. Ngoko ke, kukho isigama ukungqinelana kweenkcukacha "positive" (amaxabiso aphezulu uluhlu data ziqhagamshelwe kwizithuba amaxabiso enkulu yesinye uluhlu efanayo), i "ezimbi" ukuhlanganisa (ixabiso elincinane ifayile yeenkcukacha enye enxulumene ne kumaxabiso afanayo kwezinye uluhlu) kunye kungqinelwano ilingana zero (data kwimiboniso zibini inthanethi). Uhlalutyo ukuhlehla Microsoft Excel iya iyelenqe usebenzisa indlela statistical ezifana izikwere ubuncinane.

Ngenxa yoko, nobudlelwane kunye analysis Isemantiki kulula kakhulu ukuba uzenze kunye nokusetyenziswa kobugcisa computer mihla, uvumela ukufumana iziphumo ezinqwenelekayo ngexesha elifutshane.
