Tsim kom muaj kev faib ua pab pawg
- Nrhiav qhov loj tshaj thiab qhov tsawg tshaj plaws.
- Muab xam qhov ntau = Maximum - Yam tsawg kawg nkaus.
- Xaiv tus naj npawb ntawm chav kawm xav tau.
- Nrhiav tus chav kawm dav los ntawm kev faib qhov ntau los ntawm tus lej ntawm chav kawm thiab sib npaug.
- Xaiv qhov chaw pib tsim nyog tsawg dua lossis sib npaug ntawm tus nqi yam tsawg kawg nkaus.
Ntawm no, 3 hom kev faib tawm zaus yog dab tsi?
Hom Kev faib tawm zaus
- Pawg zaus faib.
- Ungrouped zaus faib.
- Kev faib tawm ntau zaus.
- txheeb ze zaus faib.
- Kwv tij txheeb ze sib faib zaus.
Qhov thib ob, lub hom phiaj ntawm lub rooj zaus yog dab tsi? A zaus kev faib tawm rooj tuaj yeem pab koj npaj cov ntaub ntawv no kom paub. A zaus kev faib tawm rooj yog a daim duab uas summarizes qhov tseem ceeb thiab lawv zaus . Nws yog ib txoj hauv kev zoo los npaj cov ntaub ntawv yog tias koj muaj cov npe ntawm cov lej uas sawv cev rau zaus ntawm ib qho kev tshwm sim hauv ib qho qauv.
Tsis tas li cov lus nug yog, koj ua li cas los tsim ib lub rooj zaus los ntawm histogram?
Ua ib qho Histogram Siv Lub Sij Hawm Tshaj Tawm
- Ntawm qhov ntsug axis, tso zaus. Sau lub axis no "Frequency".
- Ntawm kab rov tav axis, tso tus nqi qis ntawm txhua lub sijhawm.
- Kos ib lub bar txuas los ntawm tus nqi qis ntawm txhua lub sijhawm mus rau tus nqi qis ntawm lub sijhawm tom ntej.
Yuav ua li cas koj pom cov chav kawm ncua sij hawm nyob rau hauv ib lub rooj zaus?
Ib lub rooj zaus rau cov ntaub ntawv uas muaj ntau tus nqi ntawm cov ntaub ntawv yog tsim raws li hauv qab no:
- Txiav txim siab cov ntaub ntawv ntau ntawm cov ntaub ntawv teev.
- Txiav txim siab qhov dav ntawm cov chav kawm ib ntus.
- Faib qhov ntau los ntawm kev xaiv dav ntawm chav kawm ntu ntu los txiav txim seb muaj pes tsawg lub sijhawm.
Pom zoo:
Yuav ua li cas koj pom qhov ntau ntawm lub rooj faib zaus?
Qhov ntau yog qhov txawv ntawm qhov qis tshaj (tsawg kawg) thiab siab tshaj (qhov siab tshaj) qhov tseem ceeb. Nyob rau hauv cov ntaub ntawv no teev qhov ntau yuav yog qhov siab tshaj tus nqi rho tawm tus nqi qis tshaj. Qhov siab tshaj plaws (tus nqi siab tshaj) yog 10, qhov qis tshaj (tus nqi qis tshaj) yog 1. Yog li qhov ntau ntawm cov ntaub ntawv teev yog 9
Kuv yuav ua li cas thiaj li tau txais kuv lub rooj pivot lub rooj tsim rov qab?
Xaiv ib lub xovtooj ntawm tes hauv lub rooj pivot, nyem nyem rau ntawm koj tus nas, thiab xaiv 'Show Field List'. Qhov no yuav coj rov qab lub rooj pivot
Dab tsi yog qhov chaw ntawm lub rooj faib khoom zaus?
Cov nqe lus hauv cov txheej txheem no (8) Kev faib tawm zaus. Yog tabulation los yog pab pawg ntawm cov ntaub ntawv rau hauv Categories tsim nyog uas qhia cov naj npawb ntawm kev soj ntsuam hauv txhua pab pawg lossis pawg. Chav kawm txwv. Qib qis dua. Upper-class txwv. Chav kawm loj. Chav kawm ciam teb. Cov qhab nees. Kev faib tawm ntau zaus
Yuav ua li cas peb yuav ua kom cov chav kawm tsis hloov hauv Java nrog hnub tim?
Peb yuav nkag siab tias cov lus qhia no txhais li cas los ntawm kev tsim cov chav kawm tsis hloov nrog cov khoom sib hloov nrog Hnub tim. Tsis txhob muab cov txheej txheem "setter" - cov txheej txheem uas hloov cov teb lossis cov khoom xa mus los ntawm cov teb. Ua kom txhua qhov chaw kawg thiab ntiag tug. Tsis txhob tso cai rau subclasses override txoj kev
Yuav ua li cas koj tsim ib lub rooj hauv Teradata nrog cov lus xaiv?
CREATE TABLE active_employees AS (xaiv * Los ntawm cov neeg ua haujlwm e WHERE e.active_flg = 'Y') NROG DATA; Tsim ib daim ntawv luam ntawm ib lub rooj uas twb muaj lawm. Tsim ib daim ntawv theej tshiab ntawm lub rooj uas tsuas muaj qee qhov ntawm cov ntaub ntawv qub - ib lub subset. Tsim ib lub rooj khoob tab sis nrog raws nraim tib yam qauv ntawm tus thawj
