Feem ntau Hom ntawm Hloov pauv . Categorical sib txawv : sib txawv tshaj tuaj yeem muab tso rau hauv pawg. Nyob sib txawv : qhov tshwm sim ntawm kev sim. Raws li koj hloov lub ywj siab sib txawv , koj saib dab tsi tshwm sim rau tus neeg nyob sib txawv . Discrete sib txawv :ib sib txawv uas tsuas tuaj yeem ua rau qee tus lej ntawm qhov tseem ceeb.
Ua li no, hom sib txawv ntawm qhov sib txawv yog dab tsi?
Muaj rau 6 hom kev sib txawv:
- DEPENDENT VARIABLES.
- INDEPENDENT VARIABLES.
- INTERVENING VARIABLES.
- MODERATOR VARIABLES.
- CONTROL VARIABLES.
- EXTRANEOUS VARIABLES.
Tsis tas li ntawd, qhov piv txwv sib txawv yog dab tsi? A sib txawv yog cov yam ntxwv, tus lej, lossis ntau npaum li cas tuaj yeem ntsuas lossis suav. A sib txawv kuj tseem hu ua cov ntaub ntawv. Hnub nyoog, poj niam txiv neej, kev lag luam cov nyiaj tau los thiab cov nuj nqis, lub teb chaws yug, kev siv peev, qib kawm, qhov muag xim thiab hom tsheb yog piv txwv ntawm sib txawv.
Tom qab ntawd, lo lus nug yog, dab tsi yog 3 hom kev hloov pauv?
Tej yam uas hloov pauv hauv kev sim hu ua sib txawv . A sib txawv yog ib yam dab tsi, zoo, los yog tej yam kev mob uas muaj nyob rau hauv txawv tus nqi los yog hom . Ib qho kev sim feem ntau muaj peb hom ntawm sib txawv : ywj siab, nyob ruaj khov, thiab tswj tau.
Dab tsi yog hom kev hloov pauv hauv kev lag luam?
Ib feem ntawm qhov kev sim: Independent vs dependent variables
| Hom kev hloov pauv | Txhais |
|---|---|
| Independent variables (aka kho variables) | Cov kev hloov pauv uas koj siv tau txhawm rau cuam tshuam rau qhov tshwm sim ntawm qhov kev sim. |
| Dependent variables (aka teb variables) | Cov kev hloov pauv uas sawv cev rau qhov tshwm sim ntawm qhov kev sim. |

Dab tsi yog qhov sib txawv ntawm qhov kev txiav tawm thiab qhov kev sib cav Ampliative?
Yog hais tias tus arguer ntseeg hais tias qhov tseeb ntawm qhov chaw yeej tsim qhov tseeb ntawm qhov xaus, ces qhov kev sib cav yog deductive. Yog hais tias tus arguer ntseeg hais tias qhov tseeb ntawm qhov chaw muab tsuas yog vim li cas zoo los ntseeg qhov xaus yog tej zaum muaj tseeb, ces qhov kev sib cav yog inductive
Dab tsi yog qhov txawv ntawm cov ntaub ntawv hom thiab qhov sib txawv?
Ib qho kev sib txawv yuav tsum muaj cov ntaub ntawv sib txuas nrog nws, piv txwv li nws tuaj yeem muaj cov ntaub ntawv xws li cov lej, lej lej, cov cim thiab lwm yam. Qhov sib txawv ntawm hom Integer khaws cov lej suav thiab tus cim typevariable khaws cov cim tus nqi. Thawj qhov sib txawv ntawm ntau hom ntaub ntawv yog lawv qhov loj me me
Dab tsi yog qhov sib txawv ntawm qhov sib xyaw ua ke thiab qhov qub txeeg qub teg?
Txawm hais tias ob qho tib si Inheritance thiab Composition muab code reusablelility, qhov sib txawv tseem ceeb ntawm Composition thiab Inheritance nyob rau hauv Java yog tias Composition tso cai rov qab siv code yam tsis tau ncua nws tab sis rau Inheritance koj yuav tsum ncua chav kawm rau ib qho kev rov qab siv code lossis functionality
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
