Spearman a malumikizanidwe koyefishienti. Spearman ndi udindo malumikizanidwe koyefishienti

Mwambo "Masamu Apamwamba" mu zinthu zina kukanidwa, monga Ndithudi aliyense akhoza kuzimvetsa Izo. Koma amene wapeza kuphunzira phunziro ili ndi kuthetsa mavuto ntchito maikwezhoni osiyanasiyana ndi zinthu, akhoza kudzitama pafupifupi kumalizira osvedemlennosti. Mu sayansi maganizo, sikuti kuli zofunika zothandiza anthu, komanso ena mitunduyi ndi njira masamu zoti ziyesedwe a kungoganizira kuika patsogolo mu njira ya kafukufuku. Kuti tichite zimenezi, pali zinthu zosiyanasiyana.

Spearman a malumikizanidwe koyefishienti

Ndi muyeso ambiri adziwe ubwenzi mgwirizano wa pakati mbali ziwiri. The koyefishienti amatchedwanso sanali parametric njira. Izo zikusonyeza zochitika za pa intaneti. Kuti ndi tikudziwa, mwachitsanzo, kuti chiwawa mwanayo ndi irritability kugwirizana ndi mzake, ndi malumikizanidwe koyefishienti Spearman udindo kuwirikiza kawiri amasonyeza ubale masamu pakati zilembo ziwirizi.

Kodi kuwerengera koyefishienti udindo?

Mwachibadwa, ali chilinganizo yake imene iwo mopitirira kwa zosintha zonse kapena matanthauzo masamu. Ndipo ali ndi malumikizanidwe koyefishienti wa Spearman. Ndondomeko ali motere:

Koyamba, njira si bwino kwathunthu, koma ngati inu muyang'ana, chirichonse mosavuta kwambiri masamu:

• N - chiwerengero zizindikiro kapena zizindikiro zimene pachikhalidwe.
• D - kusiyana kwa udindo awiri yeniyeni lolingana ina zosintha ziwiri lililonse mayeso.
• Σd ^{2 -} Uwerenge mabwalo kusiyana udindo umboni, ndi mabwalo omwe mopitirira payokha udindo uliwonse.

Mbali ya miyeso masamu kulankhulana

Kutsatira muyenera Udindo koyefishienti kafukufuku kachulukidwe khalidwe anali pachikhalidwe, ndiko kuti, wakhala nambala yeniyeni malinga malo alionse amene chizindikiro, ndipo kufunika kwake. Iwo imatsimikizirika kuti mizere iwiri mbali, m'kukoma mawonekedwe n'zosangalatsa kumva, kufanana angapo. Koyefishienti Spearman udindo malumikizanidwe Mzimuyo mlingo wa concurrency, makhalidwe kugwirizana zikayamba.

Ntchito masamu pa mawerengedwe ndi mtima makhalidwe kugwirizana ndi anati koyefishienti kofunika kuti ena zochita:

1. Aliyense mtengo wa nkhani kapena chochitika wapatsidwa nambala kuti - udindo. Zimakhala zikugwirizana chodabwitsa akukwera ndi kutsika.
2. Komanso mfundo khalidwe akuyerekezedwa upainiya mizere iwiri quantified kudziwa kusiyana therebetween.
3. Mu ndime osiyana tebulo lililonse kusiyana analandira akaundula lalikulu ake, ndipo zotsatira zakambidwa mwachidule m'munsimu.
4. Pambuyo zimenezi, timatsatira chilinganizo chimene linaŵerengera, ufotokoze mwapadera koyefishienti wa Spearman.

Katundu wa malumikizanidwe koyefishienti

The katundu waukulu Spearman koyefishienti zotsatirazi:

• mfundo muyeso mu osiyanasiyana -1 1.
• kutanthauzira koyefishienti sikuloledwa.
• Kugwirizana ndi anatsimikiza ndi mfundo yakuti: apamwamba a mtengo kwambiri ubwenzi.

Kodi kuonanso ubwino analandira?

Kuti muone kugwirizana zizindikiro za kufunika kuchita zinthu zina:

1. Akuwatsimikizira null amanena (H0), ndi zofunika, ndiye winayo anakonza zina choyamba (H _1). The kungoganizira poyamba kuti Spearman malumikizanidwe koyefishienti 0 - izi zikutanthauza kuti kugwirizana sadzapezekapo. Chachiwiri, m'malo mwake, ndi kuti si koyefishienti 0, ndiye kugwirizana.
2. Sitepe yotsatira ndi kupeza mfundo anati kwa muyezo. Ndi chilinganizo zikuluzikulu zomwe koyefishienti wa Spearman.
3. Otsatira mfundo yapadera ya muyezo anakonzeratu. Izi zikhoza kuchitika kokha ndi tebulo wapadera kuonetsera ubwino osiyana magawo wapatsidwa; mlingo wa tanthauzo (l) Chiwerengero liwulo chitsanzo kukula (n).
4. Tsopano mukuyenera kuziyerekeza mfundo ziwiri chifukwa zakonzedwa kusunga, komanso yovuta. Kuti tichite zimenezi, muyenera kumanga dera yovuta. M'pofunika lembani mzere wolunjika pa izo kuona mawu a mfundo yapadera ya koyefishienti ndi chizindikiro "-" ndi "+" chizindikiro. Kumanzere ndi ufulu wa makhalidwe ovuta madontho ndi waikamo semicircles malo ovuta. Middle, kaphatikizidwe mfundo ziwiri, pali theka-bwalo la magulu m'bungwe upandu.
5. Pambuyo pake anamaliza kugwirizana yodzaza pakati zizindikiro ziwiri.

Kodi bwino ntchito mtengo uwu

The sayansi yoyambirira imene amagwira ntchito chiŵerengero ichi kunali kuwerenga. Ndipotu, ndi sayansi, si zochokera manambalawo, koma pofuna kutsimikizira malingaliro iliyonse yokhudza chitukuko cha mabwenzi, makhalidwe a anthu, nzeru za ophunzira, zowerengera chitsimikiziro cha anapezazo chofunika. Komanso, amagwiritsidwanso ntchito pa chuma, makamaka pa liwiro la ndalama. Pali akuti popanda zizindikiro ziwerengero. yabwino Spearman udindo malumikizanidwe koyefishienti chikalata chimenechi kuunikaku imagwiridwa paokha ku kufalitsa zosintha, popeza m'malo mwa nduna chiwerengero. Spearman koyefishienti mwakhama ntchito kubanki. Sociology, sayansi ndale, ntundu ndi sayansi zina ntchito mu kafukufuku wawo. Zotsatira analandira mofulumira ndi molondola monga momwe kungathekere.

Umene mofulumira ntchito Spearman malumikizanidwe koyefishienti mu kupambana. Pano pali zinthu zina zapadera zimene zingakuthandizeni mofulumira kufunika chofunika.

Kodi ena malumikizanidwe koefishienti kulibe?

Komanso, zimene taphunzira za Spearman koyefishienti wa malumikizanidwe, pali malumikizanidwe koefishienti zosiyanasiyana, kulola kuyeza, kupenda makhalidwe quality, ubale pakati pa makhalidwe kachulukidwe, ubwenzi wa Kubverana kwawo ukufanizidwa mu lonse kusanja. Izi ndi zinthu monga bisserialny apadera-bisserialny, kontengentsii, kucheza, ndi zina zotero. Spearman koyefishienti molondola akusonyeza ubwenzi kulankhulana, mosiyana ndi njira zina zonse masamu kwa mtima wake.
