Txhawm rau khiav lub bivariate Pearson Kev sib raug zoo , nyem Analyze> Correlate> Bivariate. Xaiv qhov sib txawv Qhov siab thiab qhov hnyav thiab txav mus rau hauv lub thawv Variables. Hauv Kev sib txheeb Coefficients cheeb tsam, xaiv Pearson . Hauv cheeb tsam Kev Ntsuas Qhov Tseem Ceeb, xaiv qhov koj xav tau qhov ntsuas qhov tseem ceeb, ob-tailed lossis ib-tailed.
Hais txog qhov no, koj piav qhia Pearson correlation li cas?
Pearson's Correlation Coefficient. Kev sib txheeb yog ib txoj hauv kev los tshawb xyuas qhov kev sib raug zoo ntawm ob qhov ntau, qhov sib txawv tsis tu ncua, piv txwv li, hnub nyoog thiab ntshav siab. Pearson txoj kev sib raug zoo coefficient (r) yog ib qho kev ntsuas ntawm lub zog ntawm kev sib koom ntawm ob qhov sib txawv.
Ib sab saum toj no, koj ua li cas qhia txog kev txheeb xyuas kev sib raug zoo? Daim ntawv qhia txog kev sib raug zoo yuav tsum muaj xws li:
- r - lub zog ntawm kev sib raug zoo.
- p tus nqi - qib tseem ceeb. "Qhov tseem ceeb" qhia koj qhov tshwm sim uas kab yog vim muaj caij nyoog.
- n - tus qauv loj.
- Kev piav qhia txheeb cais ntawm txhua qhov sib txawv.
- R2 - tus coefficient ntawm kev txiav txim.
Tom qab ntawd, ib tug kuj yuav nug, koj yuav ua li cas paub yog Pearson correlation tseem ceeb?
Rau txiav txim seb tus kev sib raug zoo ntawm variables yog tseem ceeb , piv cov p-tus nqi rau koj qhov tseem ceeb qib. Feem ntau, a qhov tseem ceeb qib (cim li α lossis alpha) ntawm 0.05 ua haujlwm zoo. Ib qho α ntawm 0.05 qhia tias qhov kev pheej hmoo ntawm kev txiav txim siab tias a kev sib raug zoo muaj- thaum , ua tau, tsis muaj kev sib raug zoo muaj - yog 5%.
Koj ua li cas kev txheeb xyuas kev sib raug zoo?
Txhawm rau khiav lub bivariate Pearson Kev sib txheeb , nias Txheeb xyuas > Sib txheeb > Bivariate. Xaiv qhov sib txawv Qhov siab thiab qhov hnyav thiab txav mus rau hauv lub thawv Variables. Hauv Kev sib txheeb Coefficients cheeb tsam, xaiv Pearson. Nyob rau hauv qhov kev ntsuam xyuas qhov tseem ceeb, xaiv qhov koj xav tau qhov tseem ceeb xeem, ob-tailed los yog ib-tailed.

Yog vim li cas magnesium nyob rau lub sij hawm 3 ntawm lub sij hawm?
Cov qauv ntawm cov khoom hloov pauv thaum koj mus hla lub sijhawm. Thawj peb yog hlau, silicon yog loj covalent, thiab tus so yog cov molecules yooj yim. Sodium, magnesium thiab aluminium tag nrho muaj cov qauv hlau. Nyob rau hauv magnesium, ob qho tib si ntawm nws sab nrauv electrons koom nrog, thiab nyob rau hauv txhuas tag nrho peb
Lub sij hawm twg yog californium nyob rau hauv lub sij hawm?
Cov khoom no yog ib qho khoom. Californium tau muab cais ua ib feem ntawm Actinide series raws li ib qho ntawm 'Rare Earth Elements' uas tuaj yeem nyob hauv Pawg 3 cov ntsiab lus ntawm Lub Sij Hawm Lub Sijhawm thiab hauv 6th thiab 7th lub sijhawm. Lub Ntiaj Teb Rare Elements yog ntawm Lanthanide thiab Actinide series
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nyob rau hauv lub oscilloscope?
Suav tus naj npawb ntawm kab rov tav faib los ntawm ib qho taw tes siab mus rau tom ntej (piv txwv li ncov mus rau ncov) ntawm koj lub teeb liab oscillating. Tom ntej no koj yuav muab tus naj npawb ntawm kab rov tav faib los ntawm lub sij hawm / faib kom pom lub teeb liab lub sij hawm. Koj tuaj yeem suav cov teeb liab zaus nrog qhov sib npaug no: zaus = 1 / lub sijhawm
Cov kab ntsug nyob rau hauv lub sij hawm lub sij hawm sawv cev li cas?
Cov kab ntsug ntawm lub sij hawm teev npe hu ua pab pawg lossis tsev neeg vim lawv cov tshuaj lom neeg zoo sib xws. Txhua tus tswv cuab ntawm tsev neeg ntawm cov ntsiab lus muaj tib tus lej ntawm valence electrons thiab cov khoom siv tshuaj zoo sib xws. Cov kab kab rov tav ntawm lub rooj ntu ntu yog hu ua lub sijhawm
