Processing izibalo ze data kunye neempawu zayo

Statistical lweenkcukacha kwakungenakwenzeka ngaphandle udidi lwabo, gabalala uhlalutyo. Naziphi na iziphumo kufuneka kuqala kubekwe ngendlela yokuba umntu ukufumana ulwazi omninzi oluncedo. Ukuba idatha kakhulu, ngoko ke kufuneka ukuba amaqela okanye ngokubanzi.

Ngoko ke, amaqela kuyimfuneko ukuchaza imithetho phantsi apho data ziya kusasazwa. Kulo mzekelo indlela ozikhethileyo ziya kuxhomekeka ukubonakala nje kuphela kodwa lulutho okunokwenzeka ulwazi ifunyenwe. zib ngokuchanekileyo iziphumo zophando kulula kakhulu ukuba bafunde kwaye zihlalutywe.

iindlela-manani ye nga tirhisiwaka kwiinkalo ezininzi zezinto ezenziwa luluntu lweenkcukacha. Zingakotshwa zohlulwa ngokwendidi 3 eziphambili:

1) iindlela jikelele ukuba ingasetyenziswa ngaphandle ngokuqwalasela entsimini kwesicelo;

2) iindlela kwiinkalo ezithile zemisebenzi inxaxheba kuphononongo kweenkqubo yokwenene ngezimanga;

3) iindlela ukulungiselela isifundo data ezithile.

Ngokucacileyo, indlela ngqo ngakumbi ngawo babesenza processing manani ze-data, i enemveliso kokukhona uya lokuyihlolisisa le meko eziphathekayo. Ukuba indlela yokuqala kusebenza iziphumo zenzululwazi, ixabiso eziza kuvavanywa kuphela khrayitheriya yenzululwazi, indlela wesithathu lisetyenziswa kuphela imisebenzi ethile kwindawo ethile.

Ukongeza ulwazi ngokubanzi malunga neendlela ngawo data kusetyenzwa, kukwabalulekile ukuba akwazi ukusebenza kakuhle kunye neziphumo. lweenkcukacha-manani lubandakanya ukwenza iitafile okanye iigrafu ukuze ukucaciselwa wafumana ulwazi.

Xa ulwazi lokuqala isigaba nga ishwankathelwe kule theyibhile. Umzekelo, i-processing izibalo ze-data zovavanyo ebhalwe ngendlela tabular kuvumela abaphandi ukuba ahlangule ezingaphezulu amangeno ezingeyomfuneko izikhombisi ngokulinganisa amaxabiso yeemeko ezongezelelweyo echaphazela indlela nokuhlola. Tables elula ubhale kuphela idatha sifundo okanye experiment, kodwa ukuba azihlanganisele okwakalokunje kunye neziphumo eziphambili. Noko ke, ngokuba ilungelo ukwakhiwa kwayo kuyimfuneko ukuze bacinge kwangaphambili inani elifunekayo lwemiqolo nemihlathi, bhala phantsi zonke iparameters eziyimfuneko.

A itafile kungenziwa nje ephepheni okanye ngenisa ngqo data kwi computer. Le khetho yesibini ikuvumela ukuba uhlaziye ngokukhawuleza idatha indlela ekunene ukufumana, icala, ixabiso elikhulu okanye ephantsi, ukuba azihlanganisele okanye ukufumana ixabiso avareji kweziphumo qela ekhethiweyo.

Musa ukulibala ukuba xa processing abanobuchule manani lwe data kufuna iitafile ezininzi, kufuneka ukubala beze ngamnye kunye igama elikhethekileyo.

indlela ngakumbi ibonisa sokurekhoda data imizobo. Bona abangaboni zibonisa unxulumano phakathi amaxabiso ezahlukeneyo, kube lula ukuqonda kweziphumo zophononongo.

Ukwazi imigaqo esisiseko zolwakhiwo iitafile kunye iigrafu, ungenza ngokukhawuleza nangendlela efanelekileyo lenze nokuqwalaselwa kweenkcukacha.
