Cov rov ua dua yog li ntawd tseem ceeb hauv science. Cov rov ua dua txo variability nyob rau hauv kev sim tshwm sim. Nres ntawm kev hloov pauv nce lawv qhov tseem ceeb thiab qib kev ntseeg siab. Thaum kawg, tus kws tshawb fawb tuaj yeem txiav txim siab txog ib qho kev sim.
Ib yam li ntawd, vim li cas kev rov ua dua tseem ceeb thaum tsim kev sim Simutext?
rov ua dua txhais tau hais tias txhua txoj kev kho mob siv ntau tshaj ib zaug hauv ib qho kev sim . Tseem ceeb vim nws tso cai rau peb kwv yees qhov sib txawv ntawm cov ntaub ntawv. kev kho mob yam yog variable nyob rau hauv lub kev sim , nyob rau hauv kev tswj ntawm tus neeg sim uas peb xav tias yuav cuam tshuam cov lus teb.
Ib tug kuj yuav nug, yog vim li cas replication tseem ceeb? Rov ua dua yog li ntawd, yog tseem ceeb rau ntau qhov laj thawj, suav nrog (1) kev lees paub tias cov txiaj ntsig tau siv tau thiab ntseeg tau; (2) kev txiav txim siab ntawm generalizability los yog lub luag hauj lwm ntawm extraneous variables; (3) kev siv cov txiaj ntsig rau cov xwm txheej hauv ntiaj teb tiag; thiab (4) kev tshoov siab ntawm kev tshawb fawb tshiab sib txuas cov kev tshawb pom yav dhau los los ntawm
Tsis tas li ntawd, dab tsi yog replication hauv kev sim thiab vim li cas nws tseem ceeb?
Tau txais tib yam tshwm sim thaum ib kev sim rov yog hu ua rov ua dua . Rov ua dua yog tseem ceeb hauv kev tshawb fawb kom cov kws tshawb fawb tuaj yeem "kuaj lawv txoj haujlwm." Cov txiaj ntsig ntawm kev tshawb nrhiav tsis zoo yuav raug lees paub tshwj tsis yog tias qhov kev tshawb nrhiav rov qab ntau zaus thiab cov txiaj ntsig zoo ib txwm tau txais.
Vim li cas thiaj tseem ceeb rau kev siv qhov kev sim tsim?
Kev sim tsim yog tus txheej txheem ntawm kev npaj a kawm kom ua tau raws li lub hom phiaj. Kev npaj ib kev sim zoo yog heev tseem ceeb txhawm rau xyuas kom meej tias cov ntaub ntawv zoo thiab muaj cov qauv txaus thiab lub zog muaj peev xwm los teb cov lus nug tshawb fawb txog kev txaus siab kom meej thiab ua tau zoo raws li qhov ua tau.
Pom zoo:
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Vim li cas kev ntsuas thiab ntsuas qhov tseem ceeb hauv kev tshawb fawb txog kev lag luam?
Cov nplai tau siv ntau zaus hauv kev tshawb fawb kev lag luam vim tias lawv pab hloov cov ntaub ntawv zoo (xav, kev xav, kev xav) rau hauv cov ntaub ntawv ntau, cov lej uas tuaj yeem txheeb xyuas tau. Koj tsim ib qho kev ntsuas los ntawm kev muab cov khoom (yuav ua tau piav qhia) rau tus lej
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
