Ukuhlaziywa Kwedatha Yabantu Kusetshenziswa Imidwebo Namagrafu Ukuhlaziywa kwedatha Yabantu kuyisinyathelo esibalulekile ekuhleleni intuthuko, ekwenzeni izinqubomgomo zomphakathi, kanye nokuhlolwa kohlelo lwezenhlalo nezomnotho. Imininingwane efana nosayizi wabantu, ukusatshalaliswa kwendawo, isakhiwo seminyaka, amazinga okuzalwa nokufa, kanye namazinga okufuduka ayinalutho uma ivezwa kuphela ngesimo samathebula amade. Ngakho-ke, imidwebo kanye... Funda kabanzi

Indlela Yokuhlanganisa Idatha Ngezikhawu Zamakilasi Ukuhlanganisa idatha ngezikhawu zamakilasi kuyisinyathelo esibalulekile kwizibalo ezichazayo. Umgomo ukwenza kube lula inani elikhulu ledatha eluhlaza ukuze kube lula ukufunda, ukuhlaziya, nokuveza amathebula okusatshalaliswa kwemvamisa noma ama-histogram. Uma idatha ihlukahlukene kakhulu futhi ihlakazekile, kuvame ukuba nzima ukubona amaphethini. Ngezikhawu zamakilasi, … Funda kabanzi

Ukusetshenziswa Kwezibalo Ezichazayo Ocwaningweni Lwezenhlalo Izibalo ezichazayo zingenye yezisekelo ezibaluleke kakhulu ocwaningweni lwezenhlalo. Ngaphambi kokuba abacwaningi baqhubeke nokuhlaziya okucabangayo—njengokuhlola i-hypothesis, ukuhlehla, noma ukulingisa ubudlelwano phakathi kweziguquguquko—badinga ukuqonda “ubuso” bedatha eqoqwe. Yilapho izibalo ezichazayo zisebenza khona: ukufingqa ngokuhlelekile, ukwethula, nokuchaza izici zedatha ukuze kuqondwe kalula. Kumongo we... Funda kabanzi

Amasu Okucubungula Idatha Yokuhlola Ukusebenzisa Izibalo Eziyisisekelo Ucwaningo lungenye yezindlela ezivame kakhulu zokuqoqa idatha kubaphenduli, kungaba ucwaningo lwezemfundo, ukuhlolwa kwezinsizakalo, ucwaningo lwemakethe, noma ukwenza izinqumo zenhlangano. Kodwa-ke, idatha yocwaningo ngeke ibe namsebenzi uma ingacutshungulwa ngendlela ehlelekile. Yilapho izibalo eziyisisekelo zisebenza khona: ukusiza abacwaningi ukufingqa idatha, ukuthola amaphethini,… Funda kabanzi

Ukuhlaziywa Kwedatha Yokuthengisa Kusetshenziswa Izibalo Ezichazayo Ezweni lebhizinisi elincintisanayo, idatha yokuthengisa ingaphezu nje kwerekhodi lokuthengiselana; iwumthombo wolwazi oluhlelekile olungasiza izinkampani ukuqonda ukuziphatha kwemakethe, ukuhlola ukusebenza, nokwenza izinqumo ezinolwazi oluthe xaxa. Kodwa-ke, idatha yokuthengisa ivame ukuba nkulu futhi isakazeke ngezindlela ezahlukene, okwenza kube nzima ukuyiqonda ngokubheka izinombolo... Funda kabanzi

Ukusetshenziswa Kwezibalo Ezichazayo Ocwaningweni Lwezemfundo Izibalo ezichazayo ziyingxenye ebalulekile yocwaningo lwezemfundo ngoba zisebenza ukuchaza idatha ngokufingqiwe, ngokucacile, nangokuqondakala kalula. Esimweni semfundo, idatha ivame ukuhlukahluka: amaphuzu okuhlolwa kwabafundi, imiphumela yemibuzo yokugqugquzelwa kokufunda, amazinga okuba khona, amaphuzu okufunda nokubhala, ngisho nedatha yabantu njengobudala, ubulili, kanye nesizinda sezenhlalo nezomnotho. … Funda kabanzi

Indlela Yokufunda Nokuchaza Amagrafu Ezibalo Ngendlela Efanele Amagrafu ezibalo avame ukusetshenziswa ukwethula idatha ngamafuphi nangokulula. Kusukela emibikweni yebhizinisi kanye nezindaba zezomnotho kuya ocwaningweni lwezemfundo kanye nokuthunyelwe ezinkundleni zokuxhumana, amagrafu asisiza sibone izitayela, ukuqhathanisa, kanye namaphethini okunzima ukuwaqonda kusukela ezinombolweni ezingavuthiwe zodwa. Kodwa-ke, amagrafu angadukisa futhi uma efundwa ngokushesha… Funda kabanzi

Ukuhlaziya Ukusatshalaliswa Kwedatha Kusetshenziswa Ukuphambuka Okujwayelekile Ezibalweni, ukuqonda nje "isikhungo" sesethi yedatha akwanele. Amasethi amabili edatha angaba nesilinganiso esifanayo, kodwa izici zawo zihluka kakhulu ngenxa yezinga lawo lokusatshalaliswa. Yilapho umqondo wokusatshalaliswa kwedatha uba khona obalulekile. Esinye sezilinganiso ezithandwa kakhulu, eziqinile, nezisetshenziswa njalo zokusatshalaliswa emikhakheni ehlukahlukene—kusukela kwezemfundo nakwezomnotho kuya kwezempilo—... Funda kabanzi

Amasu Okwethula Idatha Asebenzisa Ama-Ogives Ahle Nangalungile Kuzibalo, ukwethula idatha akukhona nje ukufaka izinombolo kumathebula noma kumagrafu; kumayelana nokuguqula idatha eluhlaza ibe ulwazi oluqondakalayo noluhlaziyayo. Enye indlela yokubona ngeso lengqondo evame ukusetshenziswa ukubona ngeso lengqondo amaphethini okusabalalisa imvamisa kanye nama-frequency aqongelelekayo yi-ogive. Ama-Ogives avame ukusetshenziswa lapho idatha... Funda kabanzi

Ukusebenzisa Amathebula Okusabalalisa Imvamisa Eqongelelekayo Ekucubungulweni Kwedatha: Ekucubungulweni kwedatha, ikakhulukazi kwizibalo eziyisisekelo, enye yezindlela eziphumelela kakhulu zokufingqa inani elikhulu ledatha eluhlaza ukusebenzisa ithebula lokusabalalisa imvamisa. Kodwa-ke, sivame ukudinga ulwazi hhayi nje kuphela ngokuthi mangaki idatha ewela ekilasini ngalinye, kodwa futhi nokuthi ingakanani idatha eqongelelekayo... Funda kabanzi
