Spearman correlation yog feem ntau siv los ntsuas kev sib raug zoo uas muaj qhov sib txawv ntawm qhov sib txawv. Piv txwv li, koj tuaj yeem siv Spearman kev sib raug zoo los soj ntsuam seb qhov kev txiav txim uas cov neeg ua haujlwm ua tiav qhov kev sim ua rau muaj feem cuam tshuam rau lub hlis uas lawv tau ua haujlwm.
Vim li cas peb thiaj siv Spearman rank correlation?
Spearman's Rank correlation coefficient yog cov txheej txheem uas siv tau los xaus lub zog thiab kev taw qhia (tsis zoo lossis qhov zoo) ntawm kev sib raug zoo ntawm ob qhov sib txawv. Qhov tshwm sim yuav ib txwm nyob nruab nrab ntawm 1 thiab rho tawm 1.
Thaum twg yuav tsum siv Spearman's rank correlation coefficient?
Thaum qhov sib txawv tsis nquag faib lossis kev sib raug zoo ntawm qhov sib txawv tsis yog linear, nws yuav raug pom zoo kom siv Spearman rank correlation method. Tus coefficient ntawm kev sib raug zoo tsis muaj kev faib tawm.
Vim li cas Spearman qhov kev sim siv?
Spearman's Rank Correlation Test
Spearman's Rank Correlation is a statistical test kuaj seb puas muaj kev sib raug zoo ntawm ob pawg ntawm cov ntaub ntawv. Spearman's Rank Correlation test tsuas yog siv tau yog tias muaj tsawg kawg yog 10 (qhov tseeb tsawg kawg yog 15-15) khub ntawm cov ntaub ntawv.
Vim li cas peb thiaj khiav Spearman es tsis yog Pearson correlation?
2. Ib qhov sib txawv ntxiv yog tias Pearson ua haujlwm nrog cov ntaub ntawv nyoos ntawm qhov sib txawv thaumSpearman ua haujlwm nrog qib-qhib hloov pauv. Tam sim no, yog tias peb xav tias qhov scatterplot pom qhov muag pom qhov "tej zaum yuav yog monotonic, tej zaum yuav yog linear" kev sib raug zoo, peb qhov zoo tshaj plaws thawj koom ruam yuav yog siv Spearman thiab tsis yog Pearson.
