IZIBALO

Amasu Ezibalo ku-Biology Ukusetshenziswa kwamasu ezibalo ku-biology kushintshe indlela ososayensi abaqonda ngayo izinto ezahlukahlukene zemvelo. Izibalo zivumela ukubalwa kwedatha okuyinkimbinkimbi, ukuhlonza amaphethini, kanye nokunquma ubudlelwano phakathi kwezinto eziguquguqukayo ezibonakala zingahlobene. Lesi sihloko sizochaza amasu ahlukahlukene ezibalo asetshenziswa ku-biology futhi sichaze ukuthi asetshenziswa kanjani ukuxazulula izinkinga zezinto eziphilayo. … Funda kabanzi

Ukuhlaziywa Kwezisekelo Ze-Covariance Ukuhlaziywa kwe-Covariance (ANCOVA) kuyindlela yezibalo ehlanganisa amasu okubuyela emuva nokuhlaziya ukuhlukahluka (ANOVA) ukulawula iziguquguquko ezingathonya ukuhlukahluka okuxhomeke. Umgomo oyinhloko ukuhlola umphumela weziguquguquko ezizimele kuguquko oluxhomeke ngemuva kokulawula imiphumela yeziguquguquko ezaziwa ngokuthi ama-covariates. Kulesi sihloko, sizoxoxa… Funda kabanzi

Izibalo Ekuhlaziyweni Kwezezimali Isingeniso Izibalo ziyisayensi yokuqoqa, ukuhlaziya, ukuhumusha, ukwethula, nokuhlela idatha. Ezweni lebhizinisi nezezimali, izibalo zidlala indima ebalulekile, zivumela abahlaziyi, abatshalizimali, kanye nabaphathi ukuthi benze izinqumo eziqhutshwa idatha. Ngaphandle kokuhlaziywa kwezibalo okujulile, izinqumo zezimali zivame ukuba eziqagelayo futhi eziyingozi kakhulu. … Funda kabanzi

Isivivinyo sikaMann-Whitney ku-Statistics Izibalo ziyigatsha lezibalo eliphathelene nokuqoqwa, ukuhlaziywa, ukuchazwa, kanye nokwethulwa kwedatha. Izibalo zisetshenziswa emikhakheni eyahlukene ukwenza izinqumo eziqhutshwa idatha. Enye indlela evame ukusetshenziswa kuzibalo yi-Mann-Whitney Test (eyaziwa nangokuthi i-Mann-Whitney U Test noma i-Wilcoxon Rank-Sum Test). Lena indlela engeyona i-parametric esetshenziselwa… Funda kabanzi

Ukuhlaziywa Okuhlukile Kwezibalo: Indlela Ejulile Ukuhlaziywa Okuhlukile kuyindlela yezibalo ewusizo kakhulu ekuhlanganiseni idatha ngezigaba ezahlukene. Iyithuluzi elinamandla elivame ukusetshenziswa emikhakheni eyahlukene, okuhlanganisa isayensi yezenhlalo, i-biomedicine, ezezimali, ukumaketha, kanye neminye imikhakha eminingi. Kulesi sihloko, sizohlola ngokujulile... Funda kabanzi

Izibalo Zososayensi Bedatha Izibalo ziwumkhakha ofunda ukuqoqwa, ukuhlaziywa, ukuchazwa, ukwethulwa, kanye nokuhleleka kwedatha. Kusosayensi wedatha, izibalo ziyisisekelo esibalulekile. Ososayensi bedatha basebenza nezinhlobo ezahlukene zedatha ukuze bakhiqize ukuqonda okungaqhuba ukwenza izinqumo okungcono. Ngakho-ke, ukuqonda okuphelele kwemibono ye… Funda kabanzi

Ukuhlaziywa Kwezingxenye Eziyinhloko Ezibalweni Isingeniso Ukuhlaziywa Kwezingxenye Eziyinhloko (i-PCA) kuyindlela yezibalo esetshenziselwa ukunciphisa ubukhulu bedatha ngenkathi kugcinwa izici ezibalulekile zesethi yedatha. Isetshenziswa kabanzi emikhakheni efana nokuqashelwa kwamaphethini, ukucubungula izithombe, kanye nokuhlaziywa kwedatha ye-genomic, lapho amanani amakhulu edatha angenza kube nzima ukuhumusha kanye… Funda kabanzi

Indlela Yokuqalisa Izibalo Isingeniso Izibalo yisayensi ehlose ukuqoqa, ukuhlaziya, ukuhumusha, nokwethula idatha. Ukuhlaziywa kwezibalo kuvame ukuncika ekucabangeni okuthile noma emibonweni yamathuba edinga osayizi abakhulu besampula ukuze kukhiqizwe izilinganiso ezinembile. Kodwa-ke, ezimweni eziningi, ukuthola amasampula amakhulu akusebenzi futhi akunakwenzeka. Yilapho indlela ye-bootstrap, inqubo… Funda kabanzi

Ukubaluleka Kokuhlaziywa Kwedatha Ezibalweni Izibalo yisayensi egxile ekuqoqweni, ekuhlaziyweni, ekuchazeni, ekwethulweni nasekuhleleni idatha. Ukuhlaziywa kwedatha kungenye yezingxenye ezibaluleke kakhulu zezibalo ngoba kusenza sikwazi ukwenza izinqumo ezinolwazi. Esikhathini sedijithali esigcwele idatha enkulu, ukubaluleka kokuhlaziywa kwedatha ezibalweni kuye kwanda kakhulu. Lesi sihloko… Funda kabanzi

Izimiso Zokusatshalaliswa Kwesampula Isingeniso Ukusatshalaliswa kwesampula kuwumqondo oyisisekelo kuzibalo ogxile ezicini zokusabalalisa amasampula atholwe kubantu. Izimiso zokusabalalisa amasampula zibalulekile ekucabangeni kwezibalo ngoba zisivumela ukuthi silinganise futhi sibikezele amapharamitha abantu ngokusekelwe kudatha yesampula. Ezweni langempela, ukuqoqa idatha kubantu bonke ngokuvamile akwenzeki. Funda kabanzi
