Indlela Yokubala Ama-Quartile, Ama-Decile, kanye nama-Percentile ku-Statistical Data Kuzibalo, sivame ukudinga ukwazi indawo yenani ngaphakathi kwesethi yedatha. Ukubala nje isilinganiso noma i-median akwanele, njengoba lezi zilinganiso ezimbili zingachazi ukuthi idatha isatshalaliswa kanjani nokuthi ukubonwa kuqhathaniswa kanjani nezinye. Yilapho ama-quartile nama-decile angena khona. Funda kabanzi
Ukuhlaziya Ukwehluka kanye Nokuphambuka Okujwayelekile Ekusabalalisweni Kwedatha Ezibalweni, ukuqonda ukusatshalaliswa kwedatha kubaluleke njengokuqonda amanani aphakathi njenge-mean noma i-median. Amasethi amabili edatha angaba nesilinganiso esifanayo, kodwa ukusatshalaliswa kwawo kungase kuhluke kakhulu: elinye lingase lihlanganiswe ngokuqinile eduze kwesilinganiso, kanti elinye lingase lisakazeke kabanzi. Yilapho ukwehluka kanye nokuphambuka okujwayelekile kungena khona… Funda kabanzi
Amasu Okunquma Ukuphambuka Okumaphakathi Kudatha Yezibalo Kuzibalo, ukuqonda nje "isikhungo" sedatha—isibonelo, ngokusebenzisa isilinganiso noma isilinganiso—ngokuvamile akwanele. Amasethi amabili edatha angaba nesilinganiso esifanayo, kodwa ahluke kakhulu ngezinga "lokuhluka" kwamanani awo. Ngakho-ke, izilinganiso zokuhlakazeka zibalulekile. Isilinganiso esisodwa sokuhlakazeka okulula ukuyiqonda nokusebenzisa ukuphambuka okumaphakathi... Funda kabanzi
Indlela Yokubala Ububanzi Bedatha Ekuhlaziyweni Kwezibalo Ububanzi bedatha bungenye yezindlela ezilula zokulinganisa ukuhlakazeka ekuhlaziyweni kwezibalo. Nakuba kungase kubonakale kulula, ububanzi budlala indima ebalulekile ekuhlinzekeni umbono osheshayo wezinga lokwehluka kwamanani ngaphakathi kwesethi yedatha. Empeleni, ububanzi buvame ukusetshenziswa njengesinyathelo sokuqala ngaphambi kokubala ezinye izindlela zokulinganisa ukuhlakazeka, oku… Funda kabanzi
Umehluko Phakathi Kwesilinganiso, Isilinganiso, kanye Nemodi Ezibalweni Ezichazayo Ezibalweni Ezichazayo, enye yezinhloso eziyinhloko ukufingqa idatha ukuze kube lula ukuyiqonda. Idatha enkulu, ehlukahlukene, futhi ngezinye izikhathi "engcolile" izoba nolwazi oluthe xaxa uma yethulwa ngendlela yezilinganiso zesilinganiso sesilinganiso esiphakathi. Izilinganiso ezintathu ezisetshenziswa kakhulu zesilinganiso esiphakathi ziyisilinganiso esiphakathi, esiphakathi,... Funda kabanzi
Ukusebenzisa Imodi Ukunquma Amanani Avame Ukuvela Empilweni yansuku zonke, sivame ukuhlangana nedatha: amaphuzu okuhlolwa kwabafundi, osayizi bezicathulo ezithengiswa kakhulu, izinhlobo zemikhiqizo ezithandwa kakhulu, kanye nenani lezikhalazo ezitholwa kakhulu yinkonzo yamakhasimende. Umbuzo uwukuthi, singanquma kanjani kalula ukuthi yimaphi amanani noma izigaba ezibonakala kakhulu... Funda kabanzi
Amasu Okubala Okuphakathi Kwedatha Eyodwa Neqoqwe I-median iyisilinganiso sokuthambekela okuphakathi okusetshenziswa kaningi kuzibalo. Ngokungafani nesilinganiso (isilinganiso), esengeza wonke amanani bese sihlukaniswa ngenani lamanani, i-median igcizelela "inani eliphakathi" lesethi yedatha ehleliwe. Ngenxa yokugxila kwayo endaweni, i-median imelana kakhulu... Funda kabanzi
Indlela Yokunquma Isilinganiso Noma Isilinganiso Kusethi Yedatha Isilinganiso noma isilinganiso singenye yezindlela ezisetshenziswa kakhulu zokulinganisa ukuthambekela okuphakathi kwezibalo, izibalo, kanye nokuphila kwansuku zonke. Uma umuntu ethi "ibanga eliphakathi lekilasi" noma "izindleko ezimaphakathi zenyanga," empeleni usho isilinganiso. Lo mqondo usisiza siqonde isithombe esijwayelekile sesethi yedatha ngu...

Ukuhlaziywa Kwedatha Kusetshenziswa Ama-Polygon Avamile Kuzibalo Kuzibalo, ukwethulwa kwedatha kuyisinyathelo esibalulekile ngaphambi kokufinyelela iziphetho. Idatha equkethe izinombolo ezingavuthiwe ivame ukuba nzima ukuyiqonda uma ingahlelwanga kahle futhi ingaboniswanga kahle. Enye indlela ephumelelayo yokwethula ukusatshalaliswa kwedatha ngokusebenzisa ama-polygon avamile. Ama-polygon avamile asisiza sibone amaphethini… Funda kabanzi
Amasu E-Histogram Edatha Eqoqwe I-histogram iyindlela yokwethula idatha esetshenziswa njalo kwizibalo, ikakhulukazi lapho kukhulunywa ngedatha eqoqwe. Ngokungafani neshadi lebha elijwayelekile, elibonisa izigaba ezihlukene, i-histogram ibonisa ukusatshalaliswa kwemvamisa kwedatha yezinombolo eqoqwe ngezikhawu zekilasi. Nge-histogram, singabona...
