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.
Tsis tas li ntawd, cov ntaub ntawv sib txawv yog dab tsi? 13 Hom Cov Ntaub Ntawv
- 1 - Cov ntaub ntawv loj. Hnub no hauv: Tech.
- 2 - Cov ntaub ntawv tsim qauv, tsis muaj qauv, ib nrab cov ntaub ntawv. Txhua cov ntaub ntawv muaj cov qauv ntawm qee yam.
- 3 - Cov ntaub ntawv teev sijhawm.
- 4 - Cov ntaub ntawv tshuab.
- 5 - Spatiotemporal cov ntaub ntawv.
- 6 - Qhib cov ntaub ntawv.
- 7 - Tsaus cov ntaub ntawv.
- 8 - Cov ntaub ntawv lub sijhawm tiag tiag.
Tsis tas li ntawd, qhov txawv ntawm nominal thiab ordinal cov ntaub ntawv 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.
Lub hnub nyoog puas yog ib qho qauv lossis ncua sijhawm?
Lub sijhawm -level variables yog nruam, txhais tau hais tias txhua tus nqi ntawm qhov sib txawv yog ib qho increment loj dua li yav dhau los thiab ib qho me dua tus nqi tom ntej. Hnub nyoog , yog ntsuas hauv xyoo, yog ib qho piv txwv zoo; txhua qhov nce ntxiv yog ib xyoos.
