Qhov sib piv nplai tuaj yeem muab faib ua plaub hauv qab no hom txheej txheem scaling : (a) Paired Comparison Scale , (b) Qib Order Scale , (c) Constant Sum Scale , thiab (d) Q-sort Scale.

Kuj paub, dab tsi yog cov txheej txheem scaling tseem ceeb hauv kev tshawb fawb?

Scaling Techniques hauv Kev Tshawb Fawb Kev Lag Luam

Nominal Nplai. Nominal scale yog qhov yooj yim siv tab sis muab qhov ntsuas qis tshaj plaws.
Ncua Sij Hawm. Lub sijhawm ntsuas feem ntau yog siv rau hauv kev tshawb fawb kev lag luam.
Ordinal Nplai.
Sib piv cov nplai.
Qhov ntsuas ntsuas.

Ib yam li ntawd, 3 theem ntawm kev ntsuas yog dab tsi? Cov ntaub ntawv qib kev ntsuas. Ib qho kev sib txawv muaj ib qho ntawm plaub theem sib txawv ntawm kev ntsuas: Nominal , Ordinal , Lub sijhawm , los yog Ratio. ( Lub sijhawm thiab qhov piv ntawm qhov ntsuas qee zaum hu ua Nruam lossis Nplai).

Ib yam li ntawd ib tug yuav nug, dab tsi yog 4 ntsuas ntsuas?

Cov ntaub ntawv tuaj yeem raug cais raws li nyob rau ntawm ib qho ntawm plaub teev : nominal, ordinal, interval los yog ratio. Txhua qib ntawm ntsuas muaj tej yam tseem ceeb uas yuav pab tau kom paub. Cov khoom ntawm Kev ntsuas ntsuas : Identity – Txhua tus nqi ntawm tus ntsuas ntsuas muaj lub ntsiab lus tshwj xeeb.

Cov txheej txheem ntsuas yog dab tsi?

Cov txheej txheem los yog txheej txheem siv kom tau txais cov ntaub ntawv piav qhia txog yam ntawm cov txheej txheem lossis qhov zoo ntawm cov khoom tsim tawm ntawm cov txheej txheem. Kev ntsuas cov txheej txheem yuav tsum tau sau ua ib feem ntawm Six Sigma project lossis lwm yam kev txhim kho cov txheej txheem, txhawm rau kom ntseeg tau tias kev ntsuas ntawm kev txhim kho rau cov txheej txheem yog qhov tseeb.
