Okweqile lokho. okushiwo

Isihloko esichaza indima izibalo njengoba isayensi. Umcabango kurtosis kanye nokusebenzisa kwayo kwezesayensi.

Izibalo. Umqondo oyisisekelo

Izibalo - i-esuselwe eyisisekelo isayensi zezibalo. Le nto libhekisela eziningi social sciences, okuyinto kuhloswe asathuthuka abafundi 'imidwebo indlela abheka ngayo izinto ukuhlaziywa afanele izenzakalo.

Izibalo izifundo izinqubo ezihlukahlukene futhi izenzakalo izimpilo zabantu, lokhu kuwenza ivelele amaphetheni futhi zonke ngesimo imibiko ezibalo iDemo. Lokhu isayensi yomphakathi ewusizo futhi kudinga ngcono okuqhubekayo. Okweqile - kuyini? Lona umqondo oyisisekelo izibalo sokuqhafaza, esiza ukunquma ngokunemba calculus eziphambili. I ngokweqile akufanele abe ukuphambuka eqinile.

Izibalo ikuvumela ukwanelisa isidingo abantu ngoba ukwaziswa okunokwethenjelwa mayelana ethile imihlola, imicimbi nokunye. Ukunqunywa Dynamics zokuphila izici recession, yokujama tsi noma ukukhula - yilokho impela lokhu isayensi abahlangene.

Kuleli zwe lanamuhla kwezibalo ke ingenye yezindawo eziyinhloko enkundleni ngokwesayensi. Ake sibheke umqondo wegama elithi "okungalé". Iyini injongo kwezibalo kanye nokuqapha? Lapho kusetshenziswa le miqondo? Konke lokhu, bheka kamuva kulesi sihloko.

Kuyini ngokweqile ezibalweni?

Okweqile - umqondo kwezibalo elimelela nokucija isiqongo ngamunye ukusatshalaliswa ishadi. Kukhona ifomula ekhethekile ekubaleni yayo eqondile.

Ukulindela uthi ngoba iyunifomu ngaphezulu ukusatshalaliswa izibalo kurtosis kumele ilingane nesibalo esiqondile. Ngokwezwi nezwi igama elithi leli gama lisho ukuphambuka ethile kusukela yinto evamile ukukhuluma futhi sathuthukisa angaphilile noma ekusebenzeni kwenqubo kwezibalo.

Inkulumo ngokweqile lokweqisa kugrafu kwezibalo ungakhuluma mayelana nokuziphatha okungalungile cwaningo noma iphutha eluhlaza idatha igrafu. Enje mqondo scalar ngokwemvelo, okusho ukuthi ngezinga ukuhumusha yokugcina kufanele uthole inombolo ayiqukethe eziguquguqukayo noma imisebenzi asizayo. Yilokho kurtosis.

Uyini ukusatshalaliswa lesinesitfombe-sibuko futhi quin

I ngokweqile, okuyinto ezihlobene ukusatshalaliswa uhlobo lesinesitfombe-sibuko zero. Kungenzeka ukuba babonise ukuthi usebenzisa uhlelo. igrafu Asymmetric ikhombisa esihle zero inombolo. Libhekisela ngokweqile.

Kuyini nokucija eliphakeme? Isimiso, okuyinto has iphakama abukhali, ubonisa ukuthi ukubaluleka okwedlulele - kule nombolo lingaphansi kuka-zero. Kaningi kuba nezimo lapho lo mqondo asikwazi ukuchaza ngenani elilodwa. Kulokhu, kubalulekile eduze lokususa noma plus okufanekisa ingunaphakade.
