Ib outlier tej zaum yuav yog vim qhov txawv ntawm qhov ntsuas lossis nws tuaj yeem qhia qhov kev sim ua yuam kev; cov tom kawg yog qee zaum raug cais tawm ntawm cov ntaub ntawv teeb. Ib outlier tuaj yeem ua rau muaj teeb meem loj hauv kev txheeb cais.
Xav txog qhov no, ua li cas koj pom cov txiaj ntsig hauv cov ntaub ntawv?
Ib qho point uas ntog sab nraum lub cov ntaub ntawv teeb lub innerfences yog cais raws li ib tug me outlier , hos ib tug uas ntog sab nraum lub laj kab sab nrauv yog cais raws li ib tug loj outlier . Txhawm rau nrhiav cov laj kab sab hauv rau koj cov ntaub ntawv teem, ua ntej, muab cov interquartile ntau los ntawm 1.5. Tom qab ntawd, ntxiv qhov ntawd rau Q3 thiab rho tawm ntawm Q1.
Ib sab saum toj no, kuv puas yuav tsum tshem tawm outliers ntawm kuv cov ntaub ntawv? Rau tus feem ntau, yog tias koj cov ntaub ntawv cuam tshuam los ntawm cov xwm txheej hnyav, koj ua tau khi tus input rau keeb kwm sawv cev ntawm koj cov ntaub ntawv uas tsis suav nrog outliers . Txiav txim siab nyob rau hauv rooj plaub ntawm dab tsi tus nyhuv ntawm cov outliers yog. Thiab los ntawm qhov ntawd, txiav txim siab seb koj puas xav tau tshem tawm , hloov, lossis khaws cia theoutlier tus nqi.

- Kaw koj cov ntaub ntawv outliers.
- Muab tus nqi tshiab.
- Sim ib qho kev hloov pauv.
Ib qho piv txwv ntawm qhov outlier yog dab tsi?
Outlier . ntau Ib tus nqi uas "nyob sab nraud" (ismuch me me los yog loj dua) feem ntau ntawm lwm cov nqi hauv cov ntaub ntawv. Rau piv txwv nyob rau hauv cov qhab nia 25, 29, 3, 32, 85, 33, 27, 28 ob leeg 3 thiab 85 yog " outliers ".
