Kev piav qhia Statistics . Kev piav qhia txheeb cais yog siv los piav qhia txog cov yam ntxwv ntawm cov ntaub ntawv hauv kev kawm. Lawv muab cov ntsiab lus yooj yim txog cov qauv thiab kev ntsuas. Ua ke nrog cov duab yooj yim tsom xam , lawv tsim lub hauv paus ntawm txhua qhov ntau tsom xam ntawm cov ntaub ntawv.
Tsuas yog li ntawd, dab tsi yog txhais los ntawm kev txheeb xyuas?
Kev piav qhia txheeb cais yog lub sij hawm muab rau lub tsom xam ntawm cov ntaub ntawv uas pab piav qhia, qhia lossis sau cov ntaub ntawv hauv lub ntsiab lus xws li, piv txwv li, cov qauv yuav tshwm sim los ntawm cov ntaub ntawv. Lawv tsuas yog ib txoj hauv kev los piav txog peb cov ntaub ntawv.
Koj sau ib qho kev txheeb xyuas txheeb cais li cas? Cov ntsiab lus piav qhia
- Ntxiv ib lub rooj ntawm cov ntaub ntawv nyoos hauv daim ntawv ntxiv.
- suav nrog ib lub rooj nrog cov kev txheeb cais uas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv.
- Txheeb xyuas qib lossis cov ntaub ntawv.
- suav nrog ib daim duab.
- Muab ib qho kev piav qhia ntawm koj qhov txheeb cais hauv ib nqe lus luv.
Ntawm no, hom kev piav qhia kev txheeb xyuas yog dab tsi?
Kev piav qhia txheeb cais piav lossis sau cov ntaub ntawv. Kev ntsuas ntawm lub hauv paus nyiam thiab kev ntsuas ntawm dispersion yog ob hom kev piav qhia txheeb cais . Qhov ntau, variance, thiab tus qauv sib txawv yog peb hom ntawm kev ntsuas ntawm dispersion.
Cov txheej txheem tseem ceeb ntawm kev piav qhia txheeb cais yog dab tsi?
Muaj plaub hom kev piav qhia tseem ceeb:
- Kev ntsuas zaus: * Suav, feem pua, zaus.
- Kev ntsuas ntawm Central Tendency. * Qhov nruab nrab, nruab nrab, thiab hom.
- Kev ntsuas ntawm Dispersion lossis Variation. * Ntau yam, Variance, Standard Deviation.
- Kev ntsuas ntawm Txoj Haujlwm. * Qib Qib Qib, Qib Qib Quartile.
