Testing Statistical awayefike: logic jikelele

Hypothesis - omnye wemiba ebaluleke kakhulu kuphuhliso yenzululwazi kunye nenkqubela zobugcisa. Kokuma kweziphumo iziganeko ezahlukeneyo izibakala, hypothesis kubaluleke Inkolelo theoretical component. Uphononongo olunzulu kwezi zibakala ngezimanga kuyimfuneko ukuhlola imibono yezinto. Iindlela ezisetyenziswayo yokuvavanywa le kokucingelwayo kufuneka ube kwezesayensi. Ngamanye amazwi, kuba ngenxa nimana okanye izifundo esekelwe kwimithetho-siseko yobunzululwazi esekwe kakuhle.

Ukuze ubone ukuba ukunyaniseka imibono theoretical component kukho uvavanyo hypothesis manani. Le ndlela iquka ukusetyenziswa ingummiselo statistical, ezilingana bajikeleze kukonke, owakhiwa ukufumana uhlobo oluthile umsebenzi njengako iziphumo zophando okanye abakuqapheleyo (uvavanyo-manani). Ezo uvavanyo hypothesis manani likuvumela ukuba wenze isigqibo sokugqibela malunga ukunyaniseka imibono theoretical component.

Inkqubo Uhlalutyo lwamanani idla sikhatshwe imfuneko ngokuqulunqa livavanya okucingelwayo ethile theoretical malunga abantu bafunda ezitshintshayo okanye iparameters ezizimeleyo. Uthelekiso eli cebiso nesampula data ekhoyo, kulandele uhlolo iqondo ukuthembeka imveliso, kwaye yaphunyezwa kunye nokusetyenziswa zokugweba zamanani ezithile, ebizwa - uvavanyo hypothesis manani.

Phantsi yeengcinga manani kufuneka ziqondwe iintlobo ezahlukeneyo ngeenkolelo theoretical malunga nohlobo parameters lonikezelo ezithile ezahlukeneyo random, nto leyo enokuthi phantsi zihlolwe, kukhokelwa iziphumo zophononongo kwi isampuli ejikelezayo manani. Ngamanye amazwi, hypothesis lwamanani ngokuba uqikelelo malunga neempawu abantu, ukuvavanya ukuba usebenzise iinkcukacha-manani. Ngoko, kuba nokwenzeka ukuvavanya hypothesis ukulingana kwe-avareji zabemi kunye amaxabiso athile yezinto.

uvavanyo hypothesis-manani, intsingiselo yazo kukuba ngokusekelwe kwedatha yeenkcukacha-manani ezikhoyo ukuqinisekisa okanye ukuphikisa kwingcinga mfundo kunye ingozi encinci ukuthintela isiphoso okanye impazamo lusebenza kakhulu kwaye indlela ethandwa zophando lwezenzululwazi. uvavanyo hypothesis lwenziwa kwi imithetho echaziweyo ngokungqongqo.

Khumbula njalo ukuba uvavanyo hypothesis manani na probabilistic ngokwendalo. Ngale ndlela uyakwazi ukuchaza a (ipesenti) yedijithali ngokoMthetho, amathuba kokwenza isigqibo ephosakeleyo okanye isiphelo lobuxoki phezu ukutyhilwa kweziphumo zophononongo manani ebonakalayo necacileyo okanye isiganeko. Ukuba kwemposiso okanye impazamo ayinamsebenzi, ubudlelwane manani kubalwa sifundo izibakala okanye iziganeko enokusetyenziselwa iinjongo ezithile, kunye ngaphandle kwengozi esiphoso.
