Excel, isticmaalayaashu waxay xisaabiyaan Statistics kala duwan si ay u muujiyaan kala firdhinta xogta. Sababtan awgeed, isticmaalayaashu waxay isku dayaan inay xisaabiyaan Coefficient of Variance gudaha Excel. Xisaabinta Coefficient of Variance ( CV ) waa sahlan tahay in la isticmaalo Excel's STDEV.P ama STDEV. S ee shaqooyinka la dhisay iyo sidoo kale kuwa caadiga ah Qaabacooyinka tirakoobka .

Aynu nidhaahno waxaanu haynaa xog-ururin loo tixgaliyay sida Dadka ( Set ) ama Sample oo waxaanu doonaynaa inaanu xisaabi Coefficient of Variance ( CV )

Waxay muujinaysaa inta uu le'eg yahay kala duwanaanshiyaha Ccelcelis ahaan ama Mean ee Dadka (Set) ama Sample . Marka, waxaa jira 2 qaabab kala duwan oo loogu talagalay Coefficient of Variance ( CV ). Waxay kala yihiin:

Xisaabi Isku-duwanaanta Kala-duwanaanta ee Excel

Haddii isticmaalayaashu raacaan qaacidada Tirakoobka si ay u xisaabiyaan Coefficient of Variance ( CV ), marka hore waxay u baahan yihiin ka hel weecanaanta caadiga ee Dadweynaha ( σ )  ama Sample ( S ) iyo Ccelcelis ahaan ama Macnaha ( μ ). Haddii kale, isticmaalayaashu waxay isticmaali karaan STDEV.P iyo STDEV.S si ay u xisaabiyaan Dadka iyo Sample kala duwanaanshaha Standard Deviation xisaabinta.

    Excel wuxuu bixiyaa hawlo badan oo gudaha ah si loo fuliyo Statistics kala duwan. Shaqada STDEV.P waa mid ka mid ah. Tirooyinka ayay xujo ahaan u qaadataa.

    Sida aynu hore u soo sheegnay Coefficient of Variance ( CV ) waa tirada laba qaybood (ie, Standard). leexashada ( σ ) iyo Mean ( μ )). Shaqada STDEV.P waxay helaysaa Isbeddelka caadiga ah ( σ ) ee Dadka iyo AVERAGE natiijooyinka shaqada Mean ( μ ) ama Ccelcelis ahaan .

Ka beddelka STDEV.P shaqada, Excel waxa uu leeyahay STDEV.S xogta muunadda ah si loo xisaabiyo ka leexashada caadiga ah Standard Deviation ( σ ). Si la mid ah STDEV.P shaqada, STDEV.S waxay u qaadataa tirooyinka dooddeeda. Habka caadiga ah Coefficient of Deviance ( CV ) qaacidada waa saamiga u dhexeeya Ka leexashada caadiga ah ( σ ) iyo Mean ( μ ).
