Kev Qhia Txog Kev Tshawb Fawb Hauv Koj Cov Ntawv
- Txhais tau tias: Ib txwm qhia qhov nruab nrab (tus nqi nruab nrab) nrog rau kev ntsuas ntawm qhov sib txawv (tus qauv sib txawv (s) lossis tus qauv yuam kev ntawm qhov nruab nrab).
- Zaus: Zaus cov ntaub ntawv yuav tsum tau muab sau tseg nyob rau hauv cov ntawv nyeem uas tsim nyog ntsuas xws li feem pua, proportions, los yog ratios.
Xav txog qhov no, koj ua li cas sau cov txiaj ntsig ntawm kev piav qhia txheeb cais?
Cov ntsiab lus piav qhia
- Ntxiv ib lub rooj ntawm cov ntaub ntawv nyoos hauv daim ntawv ntxiv.
- suav nrog ib lub rooj nrog cov kev txheeb cais uas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv.
- Txheeb xyuas qib lossis cov ntaub ntawv.
- suav nrog ib daim duab.
- Muab ib qho kev piav qhia ntawm koj qhov txheeb cais hauv ib nqe lus luv.
Tsis tas li ntawd, koj yuav ua li cas qhia txog qhov txhais tau tias thiab tus qauv sib txawv? APA style yog qhov tseeb heev txog cov no. Tsis tas li ntawd, tshwj tsis yog qee qhov txiaj ntsig p, feem ntau cov txheeb cais yuav tsum muab sib npaug rau ob qhov zauv. Mean thiab Standard Deviation Feem ntau qhia meej hauv kab lus: Cov qauv tag nrho yog cov hluas (M = 19.22, SD = 3.45).
Tom qab ntawd, ib tus tuaj yeem nug, koj yuav txiav txim siab li cas yog qhov txiaj ntsig tseem ceeb?
A xeem yog xam statistically tseem ceeb yog tias muaj qhov tsawg kawg nkaus qhov tshwm sim tuaj yeem tshwm sim los ntawm lub sijhawm. Ntawd yog, yog qhov tshwm sim (p) qis dua qhov pib uas pab pawg xaiv ua ntej (?), kuj hu ua alpha.
Yuav ua li cas koj txheeb xyuas lub ntsiab lus thiab tus qauv sib txawv?
Yeej, me me standard deviation txhais tau tias tias qhov tseem ceeb hauv cov ntaub ntawv txheeb cais yog ze rau txhais tau tias ntawm cov ntaub ntawv teev, on nruab nrab , thiab loj standard deviation txhais tau tias tias cov nqi hauv cov ntaub ntawv teev nyob deb deb ntawm qhov txhais tau tias , yog nruab nrab.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Vim li cas IMViC thiaj li muaj txiaj ntsig los txheeb xyuas Enterobacteriaceae?
IMViC muaj txiaj ntsig zoo thaum txheeb xyuas Enterobacteriaceae tshwj xeeb thaum siv nrog rau urease, vim tias lawv suav nrog plaub qhov kev sim indole ntau lawm kuaj, methyl liab kuaj, Voges-Proskauer kuaj thiab citrate ntau lawm kuaj uas feem ntau txheeb xyuas cov kab mob gram tsis zoo ntawm Enterobacteriaceae
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Yuav ua li cas koj txheeb xyuas cov kev sib txuas ntxiv thiab cov kab ntsug?
Cov kaum sab xis yog ob lub kaum sab xis nrog qhov sib npaug ntawm 90º. Cov ces kaum ntxiv yog ob lub kaum sab xis nrog qhov sib npaug ntawm 180º. Vertical angles yog ob lub kaum sab xis uas nws ob sab tsim ob khub ntawm opposite rays. Peb tuaj yeem xav txog cov no yog cov kaum sab xis uas tsim los ntawm X
