3.3 Cov tag nrho daim ntawv ntsuam xyuas kev ua yuam kev moj khaum

Tag nrho cov daim ntawv ntsuam xyuas kev ua yuam kev = sawv cev uas tsis + ntsuas uas tsis.

Muaj ntau ntau yam ntawm uas tsis muaj peev xwm nkag mus rau hauv kev kwv yees los ntawm cov ntawv tshawb fawb, thiab txij li thaum lub 1940s soj ntsuam tau ua hauj lwm rau systematically npaj, to taub, thiab txo cov uas tsis. Ib qho tseem ceeb tshwm sim los ntawm tag nrho cov uas rau siab no yog tag nrho cov daim ntawv ntsuam xyuas kev ua yuam kev moj khaum (Groves et al. 2009; Weisberg 2005) . Lub ntsiab kev pom los ntawm tag nrho cov daim ntawv ntsuam xyuas kev ua yuam kev moj khaum yog tias teeb meem yuav yuav grouped rau hauv ob lub ntsiab thoob: teeb meem hais txog rau cov uas koj tham nrog (sawv cev) thiab cov teeb meem muaj feem xyuam rau koj kawm dab tsi los ntawm cov neeg sib tham (ntsuas). Piv txwv li, tej zaum koj yuav xav nyob rau hauv kwv cwj pwm txog online tus kheej cov neeg laus nyob rau hauv Fabkis. Tej no kwv yees yuav tsum tau ob txawv heev hom inference. Ua ntej, los ntawm cov lus teb uas cov neeg muab, koj yuav tsum xav hais tias lawv cov xeeb ceem txog online tus kheej. Ob txhais, los ntawm cov inferred cwj pwm ntawm cov neeg, koj yuav tsum xav hais tias cov cuj pwm nyob rau hauv cov pejxeem raws li ib tug tag nrho. Tus thawj hom inference yog sau rau ntawm psychology thiab kev txawj ntse science; thiab lub thib ob hom inference yog sau rau ntawm statistics. Ib tug zoo meej piv txwv tswvyim uas phem daim ntawv ntsuam xyuas cov lus nug yuav tsim phem kev kwv yees, thiab ib tug phem qauv tswvyim uas muaj zoo meej daim ntawv ntsuam xyuas cov lus nug yuav kuj tsim kev phem kev kwv yees. Zoo kwv yees yuav tsum tau suab le caag los ntsuas thiab sawv cev. Muab hais tias tom qab, tom ntej, kuv mam li saib xyuas yuav ua li cas daim ntawv ntsuam xyuas kev soj ntsuam tau xav txog sawv cev thiab ntsuas nyob rau hauv lub dhau los lawm. Kuv xav hais tias ntau npaum li cas ntawm cov khoom no yuav tsum xyuas rau kev scienitsts, tab sis nws tej zaum yuav tshiab rau ib co ntaub ntawv tshawb fawb. Ces, Kuv mam li qhia koj yuav ua li cas cov tswv yim coj cov muaj hnub nyoog daim ntawv ntsuam xyuas kev tshawb fawb.
