STDEVP muaj nuj nqi suav cov qauv sib txawv hauv cov qauv ntawm cov ntaub ntawv. Standard deviation yog ib qho kev ntsuas ntawm ntau npaum li cas variance muaj nyob rau hauv ib pawg ntawm cov zauv piv rau qhov nruab nrab (txhais tau tias) ntawm cov zauv. Nco tseg: STDEVP tau hloov nrog txoj haujlwm tshiab hu ua STDEV. P, uas muaj tus cwj pwm zoo ib yam.
Ib yam li ntawd, Stdevp yog dab tsi hauv Excel?
Lub Microsoft Excel STDEVP kev ua haujlwm rov qab tus qauv sib txawv ntawm cov pejxeem raws li tag nrho cov pejxeem ntawm tus lej. Cov STDEVP muaj nuj nqi yog ib tug built-in muaj nuj nqi nyob rau hauv Excel uas yog categorized li Statistical Function.
Tom qab ntawd, lo lus nug yog, kuv yuav tsum siv Stdev s lossis Stdev P? STDEV . P yog siv los xam cov txheem sib txawv rau tag nrho cov pejxeem whereas STDEV . S yog siv los xam cov txheem sib txawv rau ib qho piv txwv ntawm cov ntaub ntawv. Muaj ob hom txheem sib txawv , Siab thiab qis.
Yog li ntawd, qhov txawv ntawm Stdevp thiab Stdev hauv Excel yog dab tsi?
STDEV yog siv thaum cov pab pawg ntawm cov lej raug tshuaj xyuas tsuas yog ib feem ntawm cov qauv ntawm tag nrho cov pejxeem. STDEVP yog siv thaum pab pawg ntawm cov lej raug tshuaj xyuas tiav - nws yog tag nrho cov pejxeem ntawm qhov tseem ceeb.
Dab tsi yog qhov txawv ntawm VAR thiab VARP hauv Excel?
Lus hais. Cov VarP function ntsuas cov pejxeem, thiab cov Var muaj nuj nqi ntsuam xyuas cov qauv pej xeem. Yog tias cov lus nug hauv qab muaj tsawg dua ob cov ntaub ntawv, cov Var thiab VarP kev ua haujlwm rov qab tus nqi Null, uas qhia tias qhov sib txawv tsis tuaj yeem suav.
