Processing izibalo idatha kanye nezici zayo

Ngokwezibalo ngokucubungula idatha kwakungenakwenzeka ngaphandle ukuhleleka kuka, nje okungaqondile kanye nokuhlaziywa. Noma yimiphi imiphumela kufanele kuqala ukubeka ifomu yokuthi muntu owayekwazi ukusondela ulwazi oluwusizo kakhulu. Uma idatha lungaphezu, base kudingeka aqoqwe noma generalized.

Ngakho-ke, amaqembu kudingekile ukuchaza imithetho idatha izokwabiwa ngaphansi kwazo. Kulokhu indlela ekhethiwe kuzoncika ukubonakala nje kuphela kodwa futhi iwusizo bezikhali ulwazi etholakale. Kahle babeqoqana imiphumela yocwaningo kuba lula ukufunda futhi ukuhlaziywa.

izindlela Statistical for ngokucubungula idatha singasetshenziswa sphere eziningi izenzo zabantu. Abakwazi ihlukaniswe 3 izinhlobo eziyinhloko:

1) Izindlela jikelele engasetshenziswa ngaphandle kokucabangela emkhakheni kwesicelo;

2) Izindlela ezindaweni ezithize umsebenzi abathintekayo ekuhloleni izinqubo zangempela kanye izenzakalo;

3) izindlela lapho kutadishwa idatha ethile.

Ngokusobala, indlela eqonde kakhulu ngawo eyenziwa ukucutshungulwa lezibalo idatha, ufeze ngaphezulu sizohlaziya isimo ukhonkolo. Uma indlela yokuqala esebenza ngemiphumela zesayensi, ukubaluleka okuyinto bazohlolwa kuphela ngemibandela yesayensi, indlela yesithathu isetshenziswa kuphela imisebenzi ethile endaweni ethize.

Ngaphezu ulwazi olujwayelekile mayelana izindlela idatha icutshungulwe, kubalulekile ukwazi ukuthi asebenze kangcono imiphumela. Ngokwezibalo ngokucubungula idatha kuhilela ukudala amathebula noma amagrafu ukuzwakala wathola ulwazi.

In ulwazi esigabeni sokuqala kungaba efingqiwe ethebuleni. Ngokwesibonelo, processing izibalo idatha zokuhlola eqoshiwe ngefomethi tabular kuvumela abacwaningi ukuletha extra okufakiwe ezingadingekile izinkomba ukulinganisa amanani yezici ezingeziwe ezithinta inkambo ukuhlola. Amathebula elula ukurekhoda hhayi kuphela idatha cwaningo noma ukuhlolwa, kodwa ngamafuphi Okwesikhashana futhi imiphumela esemqoka. Nokho, ilungelo ukwakhiwa yabo okudingeke ukuba akucabange kusengaphambili inani elidingekayo lemigqa namakholomu, abhale phansi wonke nemingcele ezidingekayo.

A ithebula kungenziwa nje ephepheni noma ngqo faka idatha ku computer. Indlela yesibili ikuvumela ukuba ngokushesha ukuhlunga idatha ngendlela efanele ukuze uthole ngobukhulu noma, Ngakolunye uhlangothi, i-value ephansi, ngamafuphi noma ukuthola inani eliyisilinganiso imiphumela neqembu.

Ungakhohlwa ukuthi uma ngabe ukucubungula abanekhono ngokwezibalo kwemininingwane yocwaningo idinga amatafula amaningi, kumele olunezinombolo bona futhi ngamunye beveza igama elehlukile.

indlela Okuningi engokomfanekiso ukurekhoda idatha ihluzo. Bona zibukeke ukubonisa ubudlelwane phakathi namanani ahlukene, lula ukuqonda imiphumela yocwaningo.

Ukwazi izimiso eziyisisekelo ukwakhiwa amathebula kanye amagrafu, ungakwazi masinya enze ukucutshungulwa idatha.
