Qhov kev ywj pheej (lossis tswj hwm) qhov sib txawv yog qee yam uas tus kws sim lub hom phiaj hloov pauv lossis txawv ntawm qhov kev tshawb nrhiav. Qhov dependent (los yog teb) sib txawv yog ib qho uas tau pom thiab yuav hloov pauv hauv cov lus teb rauqhov sib txawv ntawm tus kheej.
Yuav ua li cas hloov pauv tsis tuaj yeem tswj tau?
Cov kev tshawb fawb no muaj ntau heev, thiab muaj ob peb lub ntsiab lus tsim nyog ua txog lawv. Ua ntej, kev hloov pauv tsis muaj kev ywj pheej feem ntau yog tus neeg koom tes sib txawv(lub cev tsis nco qab, hypochondriasis, kev hwm tus kheej, thiab lwm yam), thiab xws li lawv yog los ntawm kev txhais ntawm cov ntsiab lus.
hom kev hloov pauv twg tuaj yeem hloov kho?
Independent variables (IV): Cov no yog cov xwm txheej lossis cov xwm txheej uas koj siv hauv kev sim. Koj qhov kev xav yog qhov sib txawv no ua rau muaj kev cuam tshuam ncaj qha rau qhov sib txawv ntawm qhov sib txawv.
Puas yog qhov hloov pauv hloov pauv los ntawm tus kws tshawb fawb?
Yog li ntawd, hauv kev sim, tus tus kws tshawb nrhiav tswj hwm qhov hloov pauv ywj pheejlos txiav txim seb nws ua rau muaj kev hloov pauv hauv qhov sib txawv. Raws li peb tau kawm dhau los hauv txoj kev tshawb fawb piav qhia, cov kev hloov pauv tsis raug tswj xyuas. Lawv raug soj ntsuam raws li lawv ib txwm tshwm sim thiab tom qab ntawd kev sib koom ua ke ntawm qhov sib txawv tau kawm.
Yuav ua li cas yog qhov kev tswj hwm ntawm qhov hloov pauv ywj pheej?
Dua, txhawm rau tswj hwm qhov sib txawv ntawm tus kheej txhais tau tias hloov nws qib systematically kom cov pab pawg sib txawv ntawm cov neeg koom tau nthuav tawm ntau theem ntawm qhov sib txawv ntawd, lossis tib pab pawg neeg koom yog nthuav tawm rau ntau qib sib txawv ntawm lub sijhawm sib txawv.
Pom zoo:
Dab tsi yog qhov hloov pauv hloov pauv tau?
Subscripted Variable. Subscripted variables yog siv los khaws cov txiaj ntsig ntawm tib hom hauv ib qho array. Nws kuj tseem pab peb khaws cov txiaj ntsig ntau dua hauv ib lub npe sib txawv. Subscripted variables tau tshaj tawm los ntawm kev muab lub npe sib txawv nrog rau cov ntawv sau npe .
Puas hloov pauv hloov pauv tuaj yeem hloov kho?
Nyob hauv ntau qhov kev sim, qhov sib txawv ntawm kev ywj pheej yog kev tsim kho uas tsuas yog tuaj yeem tswj tsis ncaj . Puas yog qhov sib txawv nyob ntawm qhov ntsuas lossis tswj tau? Ib qhov sib txawv yog qhov ntsuas lossis manipulated hauv kev sim.
Qhov twg yog qhov hloov pauv hloov pauv mus rau ntawm daim duab?
Thaum peb npaj cov ntaub ntawv ntawm ib daim duab qhov kev hloov pauv hloov pauv yog ib txwm npaj rau ntawm X - axisthiab qhov sib txawv teb yog ib txwm npaj rau ntawm Y - axis. Independent variable yog lwm lub npe rau kev hloov pauv hloov pauv.
Kev hloov pauv hloov pauv tuaj yeem nyob twj ywm?
“ Silent” kev hloov pauv: tsis hloov pauv cov amino acid, tab sis qee zaum tseem tuaj yeem muaj cov nyhuv phenotypic, xws li, los ntawm kev ua kom nrawm lossis ua kom qeeb ntawm cov protein synthesis, lossis los ntawm kev cuam tshuam splicing.
Puas muab kev pauv pauv hloov pauv tau?
Kev ua lag luam tuaj yeem yog thim rov qab los ntawm kev tso cai thim rov qab, los ntawm cov nyiaj rov qab, lossis los ntawm kev them rov qab. Lub caij no, cov tub lag luam tsuas tuaj yeem tiv thaiv kev thim rov qab los ntawm kev deflection lossis sawv cev.
