Spearman sika ukuhlanganisa Coefficient. Spearman sika isikhundla ukuhlanganisa Coefficient

Isiyalo "Ephakeme Mathematics" kwezinye izimbangela kwenqatshwa, njengoba ngempela hhayi wonke umuntu ungaqonda. Kodwa labo nenhlanhla yokuthola ukufunda ngale ndaba futhi uxazulule izinkinga besebenzisa zibalo ahlukahlukene kanye izici, kungaba ozibongayo i cishe awuqede osvedemlennosti. Esikhathini isayensi ezingokwengqondo, kukhona focus hhayi kuphela yobuntu, kodwa futhi amafomula ethile nezindlela zezibalo ukuhlola umbono phambili ngokuhamba ucwaningo. Ukuze wenze lokhu, kukhona izinto ezahlukene.

Spearman sika ukuhlanganisa Coefficient

Kuyinto nesilinganiso ezivamile sokunquma abasondelana ukuhlobana kwemikhosi yiziphi izici ezimbili. Coefficient ubizwa nangokuthi indlela non-parametric. Ibonisa izibalo uxhumano. Okungukuthi, siyazi, isibonelo, ukuthi ulaka wengane kanye nobuhlungu ezihlobene nomunye, futhi ukuhlanganisa Coefficient Spearman isikhundla isibalo ubonisa ubuhlobo zezibalo phakathi lezi zinhlamvu ezimbili.

Wenzenjani ukubala Coefficient isikhundla?

Ngokwemvelo, it has ifomula ayo ngazo kubalwa kuwo wonke eziguquguqukayo noma izincazelo zezibalo. Futhi has a Coefficient ukuhlanganisa of Spearman. Ifomula yena simiswe ngalendlela lelandzelako:

Uma uthi nhlá, ifomula Akucaci ngokuphelele, kodwa uma ubheka, yonke into kalula kakhulu kubalwa:

• n - inombolo izimpawu noma izinkomba ukuthi zibekwa.
• d - umehluko isikhundla ezimbili eziqondile elihambisana ethile ezimbili eziguquguqukayo kokuhlolwa ngalinye.
• Σd ^{2 -} isamba sezikwele ukwahluka isikhundla inkomba, izigcawu lapho kubalwa ngokuhlukile isikhundla ngamunye.

Ububanzi zezibalo izinyathelo zokuxhumana

Ukuze ukwazi ukufaka isicelo kumele lilinganise Coefficient kudatha imfanelo ambalwa abangu zibalwa, okungukuthi, liye inikezwa inamba ethize kuncike indawo enikezwe uphawu, futhi ngokujulile ukubaluleka kwaso. It is wafakazela ukuthi izinhlu ezimbili zamahalananda izici, obonakaliswe ifomu zezinombolo, parallel eziningana. Coefficient Spearman isikhundla ukuhlanganisa inquma degree of concurrency, uxhumano yobunzima izici.

Ngomsebenzi wokugqokwa zezibalo ku ukubala nokuzimisela uxhumano izici by Coefficient wathi kunesidingo ukwenza izenzo ezithile:

1. Inani ngalinye kwanoma yisiphi isihloko noma mcimbi wanikezwa inombolo ukuze - isikhundla. Kungaba ukufanisa mkhuba zehla zenyuka.
2. Ngaphezu kwalokho amagugu isici uqhathaniswa kwababusi imigqa emibili quantified ukucacisa therebetween umehluko.
3. Ngo ikholomu ehlukile itafula umehluko ngamunye etholwe nerejista square yayo, futhi imiphumela ibekwe kafushane lapha ngezansi.
4. Ngemva lezi zinyathelo, sisebenzisa ifomula ukuthi sinquma Coefficient ukuhlanganisa of Spearman.

Properties of ukuhlanganisa Coefficient

I izakhiwo eyinhloko Spearman Coefficient zihlanganisa lokhu okulandelayo:

• Amanani Ukumeda ku uhla -1 kuya ku-1.
• ukutolika Coefficient akuvunyelwe.
• Abasondelana ngayo ubuhlobo kunqunywa isimiso: ayanda ukubaluleka, sisondelene ubudlelwane.

Indlela hlola ukubaluleka etholwe?

Ukuhlola uxhumano phakathi izimpawu isidingo ukwenza izenzo ezithile:

1. Udlulisela null hypothesis (H0), kuba eziyisisekelo ke omunye zavela, okunye kuqala (H _1). Umbono wokuqala kungaba ukuthi Spearman ukuhlanganisa Coefficient kuyinto 0 - lokhu kusho ukuthi uxhumano ngeke. Okwesibili, kunalokho, kuba ukuthi hhayi Coefficient kuyinto 0, bese ukuxhumana.
2. Isinyathelo esilandelayo ukuthola amanani waphawula we umbandela. Kuyinto ifomula zokungabi Coefficient Spearman.
3. Okulandelayo amagugu sigxeke umbandela kusengaphambili. Lokhu kungenziwa kuphela itafula ekhethekile kokubonisa value ehlukile nemingcele ezinikezwe: ezingeni ukubaluleka (l) kanye nenani ngokuchaza usayizi isampula (n).
4. Manje kudingeka uqhathanise amanani amabili okuholela asethwe kute ukhone kubuka, kanye ezibucayi. Ukuze wenze lokhu, kufanele ukwakha esifundeni ezibucayi. Kuyadingeka ukuba ukudweba umugqa oqondile kuyo ukuze uqaphele ngokuya amagugu abagxeka Coefficient uphawu "-" futhi uphawu "+". Kwesobunxele kanye kwesokudla amagugu abagxeka amachashazi kuthiwa imali semicircles ezindaweni ezibucayi. Ephakathi, ngokuhlanganisa amanani amabili, kukhona lulwimi umbuthano amaqembu obugebengu obuhleliwe.
5. Ngemva kwalokho kuphetha isixhumanisi ophithizelayo phakathi izimpawu ezimbili.

Lapho ngcono ukusebenzisa lesi silinganiso

Isayensi lokuqala kakhulu okuyinto ngenkuthalo wasebenzisa leli isilinganiso kwaba kwengqondo. Phela, kuyinto isayensi, hhayi ngokusekelwe izibalo, kodwa ukuze ubufakazi banoma iliphi imicabango ebalulekile ethinta ukuthuthukiswa ubudlelwano, izici zobuntu abantu, ulwazi abafundi ', isiqinisekiso kwezibalo okutholakele edingekayo. Futhi, isetshenziswa emnothweni, ikakhulukazi ngesivinini lwemali. Kukhona kulinganiselwa ngaphandle izimpawu izibalo. elula kakhulu Spearman isikhundla ukuhlanganisa Coefficient kulolu hlelo lokusebenza ukuthi ukuhlolwa kwenziwa ngokuzimela ukusatshalaliswa lokwehlukile, ngoba esikhundleni simo inombolo. Spearman Coefficient ngenkuthalo lisetshenziswe yasebhange. Sociology, wezifundo zezombusazwe, Ukucwaninga kanye neminye imikhakha yesayensi futhi silusebenzise ucwaningo lwabo. Imiphumela etholakala ngokushesha futhi ngokunembe ngangokunokwenzeka.

Ihlangene futhi ngokushesha usebenzisa Spearman ukuhlanganisa Coefficient Excel. Lapha, zikhona izici ezikhethekile ukusiza ukuthi uthole masinyane ukubaluleka edingekayo.

Yimaphi amanye okuza ukuhlanganisa khona?

Ngaphezu kwalokho, lokho esikufundile mayelana Spearman Coefficient ukuhlanganisa, kukhona ukuhlanganisa okuza ahlukahlukene, okuvumela ukukala, ukuhlola izici izinga, ubudlelwano phakathi kwezimfanelo ambalwa, abasondelana ngayo ubuhlobo phakathi kwabo umelwe ku esikalini simo. Lezi zici efana bisserialny, isikhundla-bisserialny, kontengentsii, inhlangano, kanjalonjalo. Spearman Coefficient kubonisa ngokunembile abasondelana zokuxhumana, ngokungafani nazo zonke ezinye izindlela zezibalo ngenxa yokuzimisela yayo.
