Umqondo owodwa ovame ukusetshenziswa kuzibalo ukuchaza idatha yi-percentile. I-percentile inani elihlukanisa idatha ibe yizingxenye eziyikhulu ezilinganayo. Ku… Funda kabanzi
Ama-Quartiles Edatha Eqoqwe Isingeniso Izibalo, njengegatsha lesayensi elibhekene nokuqoqwa, ukuhlaziywa, ukuchazwa, ukwethula, kanye nokuhlela idatha, zinemiqondo eminingi ebalulekile esiza ekwenzeni izinqumo eziqhutshwa idatha. Umqondo owodwa obalulekile wezibalo ekuhlaziyweni kwedatha ama-quartiles. Ama-Quartiles asiza ukuqonda ukusatshalaliswa kwedatha nokuthi idatha iqoqwa kanjani ngamaqoqo. Kulesi sihloko, sizo… Funda kabanzi
Ama-Quartile Esethi Yedatha Eyodwa: Ukubheka Ngokujulile Ukusatshalaliswa Kwedatha Kuzibalo Omunye wemibono eyisisekelo kuzibalo ukuhlukanisa idatha ibe ama-quartile. Ama-Quartile asetshenziselwa ukuqonda ukusatshalaliswa kwedatha ngokuningiliziwe kunokubheka nje i-median noma i-mean. Kulesi sihloko, sizoxoxa ngama-quartile esethi yedatha eyodwa, ukuthi singawabala kanjani, kanye nokusetshenziswa kwawo ku… Funda kabanzi
Izibalo ziyigatsha lezibalo eliphathelene nokuqoqwa, ukuhlaziywa, ukuchazwa, kanye nokwethulwa kwedatha. Ezingeni lesikole samabanga aphezulu, izibalo ziyingxenye ebalulekile yekharikhulamu yezibalo ngoba zisiza abafundi baqonde ukuthi idatha isetshenziswa kanjani ezicini ezahlukene zokuphila. Omunye wemibono eyisisekelo efundwayo kuzibalo "isilinganiso sokubeka." Lesi sihloko sizoxoxa ngokujulile ngesilinganiso sokubeka, izinhlobo zaso, kanye... Funda kabanzi
Isigaba Esimaphakathi Nesemodi Sedatha Eqoqwe Idatha yezibalo ibilokhu iyisici esibalulekile ezifundweni zesayensi, ebhizinisini, kwezomnotho, nakweminye imikhakha ehlukahlukene. Empeleni, idatha yezinombolo ingahlaziywa ngezindlela ezahlukene, enye yazo ngokusebenzisa izindlela zokulinganisa ukuthambekela okuphakathi. Izindlela ezimbili ezibalulekile zokuthambekela okuphakathi ekuhlaziyweni kwedatha eqoqweni isigaba esimaphakathi nesemodi. Lesi sihloko sizohlola incazelo… Funda kabanzi
Isilinganiso Sedatha Eqoqwe: Umqondo, Ukubala, kanye Nokusetshenziswa Isingeniso Isilinganiso, noma lokho esivame ukukwazi njengesilinganiso, singenye yezindlela ezisetshenziswa kakhulu zokulinganisa ukuthambekela okuphakathi kwezibalo. Kudatha eqoqwe, ukubala isilinganiso akulula njengokubala isilinganiso samaphuzu edatha ngamanye ngoba kuhilela ukuhlanganisa idatha ngezigaba noma amakilasi athile. Lesi sihloko sizohlola ngokujulile… Funda kabanzi
Ukusebenzisa Izinga Lokuba Sesimeni Esiphakathi: Izinto Ezibalulekile kanye Nezicelo. Izinga lokuba sesimeni esiphakathi ziyimiqondo ebalulekile kuzibalo ezibhekisela kusethi yamanani abonisa phakathi kwesethi yedatha. Inhloso yazo ukunikeza umbono jikelele wamanani avame ukuvela noma isikhungo sokusatshalaliswa kwedatha. Izinga lokuba sesimeni esiphakathi zibalulekile ekuhlaziyweni kwedatha nasekucwaningweni ngoba zisivumela ukuthi sibone ukumelwa… Funda kabanzi
Isilinganiso: Isilinganiso noma Isilinganiso Isilinganiso noma isilinganiso singenye yemiqondo eyisisekelo kakhulu kwizibalo. Sivame ukusetshenziswa emikhakheni ehlukahlukene, kusukela kwezemfundo nakwezomnotho kuya kwisayensi. Kulesi sihloko, sizoxoxa ngokujulile ukuthi iyini isilinganiso, ukuthi singabalwa kanjani, nokuthi sihunyushwa futhi sisetshenziswa kanjani empilweni yansuku zonke. Iyini i-mean?
