Ukuhlanganisa futhi ukuhlehla ukuhlaziywa kanye nokusebenza kwayo ububanzi emnothweni

izindlela kwezibalo Basic Sekuyisikhathi eside esetshenziswa kuzo zonke izindawo yizenzo zabantu. Nokho, indima ebaluleke kunazo zonke eyadlalwa izibalo emnothweni. Phela, leli gatsha wesayensi alawule ubudlelwano kwezenhlalo noma kwezomnotho izinhlangano ibhizinisi wahlanganyela kule ukuhlaziywa nokucutshungulwa omkhulu amanani kolwazi.

Isikhathi esining impela ezifundweni kwezomnotho ukuthola isixazululo senkinga ekukhombeni ezinquma ukuthi ezingeni yenqubo Dynamics emnothweni. inkinga Enje ngokuvamile ukuzixazulula ukuhlanganisa futhi ukuhlehla ukuhlaziywa. Ukuze kuzuzwe ukuthembeka ukuhlaziywa kubalulekile hhayi kuphela ukubona ubudlelwano ezithile, kodwa futhi uningilize lezi izinkomba.

Ukuhlanganisa futhi ukuhlehla ukuhlaziywa ukuzixazulula le nkinga, ukuze avivinye hypothesis yezibalo maqondana khona namandla ukuhlanganisa. inombolo ezanele izici ezithinta inqubo umnotho, akuzona eziguquguqukayo okungahleliwe. Leli qiniso ukhonza njengelungu imfuneko ukuhlaziywa kwezomnotho izenzakalo isici ubudlelwane phakathi kwamagugu okungahleliwe futhi okungezona okungahleliwe. La mazwi ngokuthi ekuhlehleni ngakhoke indlela kwezibalo, okuyinto study kubo - ekuhlehleni ukuhlaziywa.

Ngenxa ukuthuthukiswa okuqhubekayo computer, ukusetshenziswa kobuchwepheshe khompyutha ngokwethukela kusetshenziswa izibalo kwezibalo. Ngakho, ukusetshenziswa ethile ye-computer kwezibalo idatha ukucutshungulwa isofthiwe ikuvumela ukuba ukuxazulula ngokushesha izinkinga ngobuhlobo nemingcele ahlukahlukene usebenzisa ekuhlehleni ukuhlaziywa.

Ngakho, ukuhlanganisa kanye ekuhlehleni ukuhlaziywa (isibonelo) ngokwanele ubonisa ukusetshenziswa kwalo ngohlelo-Microsoft Excel uma sicubungula idatha exchange rate.

UHlelo Lokungena Emibikweni Ye I yamathuluzi ikuvumela ukuba uxazulule izinkinga eziyinkimbinkimbi kwezibalo nobunjiniyela usebenzisa isethi okhethekile sokuhlaziya idatha amathuluzi. Ukuhlanganisa futhi ukuhlehla ukuhlaziywa Excel wenziwa nge inkomba oyisibopho idatha input bese kukhethwa imingcele kokuqala. Ukuhlaziywa ngokwayo ukuqhutshwa ngeBhayibheli Macro kwezibalo (iyatholakala ubunjiniyela umsebenzi), umphumela ibekwa ububanzi okukhipha ukuthi kungenziwa eshiwo umsebenzisi. Uma usebenzisa ezinye izindlela lolu hlelo, singathola yi ngefomu sokuqhafaza.

Ngosizo umfanekiso umhlaziyi ingcaca ungabona kuvumelana kwetinhlavu idatha kwezibalo. Le modi kusiza kakhulu umbono nokuqonda imiphumela.

Ngokwesibonelo, lapho ukuxuba izibalo ithebula ngesinye isikhathi kunzima ukubona amaphutha noma ukungalungi. Ukumelwa njengoba igrafu idatha ikuvumela ukuba ngokushesha futhi kalula ukuthola ngeziphambeko kanye anomalies, waba ukwanda okukhulu noma idatha iconsi, nakuba etafuleni akusho wawusho izici enjalo engemihle.

Ukuhlanganisa-Microsoft Excel ithuluzi iphakethe. Ingasetshenziselwa uningilize ubuhlobo amasethi idatha eziningana. Ukuhlanganisa ukuhlaziywa kungaba ukusungula ubuhlobo e ubukhulu amasethi wedatha. Ngakho, kukhona imiqondo "omuhle" ukuhlanganisa (izindinganiso eziphakeme ngamakhono ahlukahlukene idatha zixhumene nezindinganiso ezifanayo enkulu yesinye afanayo), i- "omubi" ukuhlanganisa (inani elincane ifayela idatha okuhlotshaniswa ne amagugu efanayo omunye afanayo) kanye ukuhlanganisa kulingana zero (idatha the kumalungu afanayo amabili ayixhunyiwe). Regression ukuhlaziywa e-Microsoft Excel ugobe usebenzisa indlela yezibalo ezifana okungenani izikwele.

Ngakho, ukuhlanganisa kanye ekuhlehleni ukuhlaziywa kuba lula kakhulu ukuba afeze nokusetshenziswa ubuchwepheshe bama-computer anamuhla, okuvumela ukuthola imiphumela efiselekayo ngesikhathi esifushane.
