Hauv Cov ntsiab lus, nominal variables yog siv rau "lub npe," los yog sau ib tug series ntawm qhov tseem ceeb. Ordinal nplai muab cov ntaub ntawv zoo txog qhov kev txiav txim ntawm kev xaiv, xws li hauv cov neeg siv khoom txaus siab kev soj ntsuam. Lub sijhawm nplai muab peb qhov kev txiav txim ntawm qhov tseem ceeb + lub peev xwm los ntsuas qhov sib txawv ntawm txhua ib.

Ua raws li qhov no hauv kev xav, qhov txawv ntawm cov ntaub ntawv nominal thiab ordinal yog dab tsi?

Cov ntaub ntawv nominal yog ib pawg ntawm cov tsis-parametric variables, thaum Ordinal cov ntaub ntawv yog ib pawg ntawm cov tsis-parametric txiav txim hloov pauv. Txawm hais tias, lawv yog ob qho tib si tsis yog qhov sib txawv, qhov txawv ntawm lawv yog qhov tseeb cov ntaub ntawv ib txwm muab tso rau hauv qee yam kev txiav txim los ntawm lawv txoj haujlwm.

Qhov thib ob, hom ntaub ntawv twg yog qhov ntsuas? Cov ntaub ntawv tuaj yeem raug cais raws li nyob rau ntawm ib qho ntawm plaub nplai: npe , kev cai , lub sijhawm los yog piv . Txhua qib kev ntsuas muaj qee yam khoom tseem ceeb uas yuav pab tau kom paub. Piv txwv li, tsuas yog cov piv scale muaj lub ntsiab lus zeros. Daim ntawv qhia ncuav qab zib qhia cov pab pawg ntawm npe variables (i.e. qeb).

Yog li ntawd, dab tsi yog qhov piv txwv ntawm cov ntaub ntawv teev tseg?

Ordinal cov ntaub ntawv yog cov ntaub ntawv uas tau muab tso rau hauv qee yam kev txiav txim lossis nplai. (Ib zaug ntxiv, qhov no yog qhov yooj yim kom nco qab vim kev cai suab zoo li kev txiav txim). Ib piv txwv ntawm cov ntaub ntawv ordinal yog ntsuas kev zoo siab ntawm qhov ntsuas ntawm 1-10. Hauv nplai cov ntaub ntawv tsis muaj tus nqi tsim nyog rau qhov sib txawv ntawm ib tus qhab nia mus rau lwm qhov.

Dab tsi yog qhov sib txawv ntawm ordinal thiab interval cov ntaub ntawv?

1. Ordinal cov ntaub ntawv muaj kev txhawj xeeb tshaj plaws txog qhov kev txiav txim thiab qeb duas thaum interval cov ntaub ntawv muaj kev txhawj xeeb txog cov sib txawv ntawm tus nqi hauv ob qhov nqi sib law liag. 2. Ordinal cov ntaub ntawv tso ib qho tseem ceeb rau txoj hauj lwm ntawm ib lub teev thaum interval cov ntaub ntawv nyob ntawm tus nqi sib txawv ntawm ob tus nqi hauv a nplai.
