Statistical mwachidule - ndi chiyani ichi? Ndondomeko ndi mitundu

Statistical mwachidule - izi ndi zokhudza limodzi anthu wagawo phunziro zomwe izo ku mbali zosiyana. Landirani atatha koyamba Kupenda sitepe. Zotsatira za malipoti zowerengera umatulutsa generalization ndi systematization zizindikiro anazindikiritsidwa mu ndondomeko chidwi.

mtengo

Chidule (gulu) zakuthupi zowerengera amalola kupeza mbali ndi makhalidwe a anthu onse, ndi kudziwa mbali zosiyana, kupeza dongosolo kusanthulidwa chuma, ndondomeko chikhalidwe ndi zochitika. Chotero systematization - mwachidule mfundo yaikulu zowerengera.

magawo a ntchito

Chidule ziwerengero ndi grouping kumafuna magawo angapo osiyana. Pambuyo pa kusanthula koyamba imagwiridwa processing zotsatira analandira, cholinga ndi kuti mudziwe zowombetsa mkota za ndondomeko pansi kuphunzira kapena chodabwitsa ndi makhalidwe ena.

Statistical mwachidule - chifukwa analandira pambuyo processing mfundo pachiyambi. Zimatengera kusinthika kuchokera deta konkire zambiri zokhudza chito ndi zinthu wamba, amene chibadidwe ndondomeko kapena chodabwitsa lonse.

Kodi mwachidule zowerengera? Masitepe kukhazikitsa ake otsatirawa:

• kuyambirira ulamuliro; apa ndi kufufuzidwa zokhudza chodabwitsa ndi (ndondomeko) deta;
• kufalitsa makhalidwe ena zizindikiro zonse;
• chilengedwe pa maziko a zizindikiro zilipo zowerengera pa tebulo.

Zimenezi ndi zofunika kuonetsetsa kuti mfundo inakhazikitsa mu mawonekedwe a matebulo zowerengera, mosapita zosavuta kuwerenga.

Gawo

Taganizirani mitundu ikuluikulu malipoti zowerengera. Kuonetsetsa losavuta ndi mawonekedwe zovuta. Information pa mayunitsi munthu mwachidule lonse, osati nagawira mu mitundu homogeneous.

Mapeto adzakhala zowerengera chidule wamba zilipo pambuyo chithandizo cha chuma. Komanso, ali ndi phindu yeniyeni ndi nkhani.

NKHANI ziwerengero yosavuta

Zambiri zowerengera mwachidule - opareshoni kuti amagwirizana ndi mawerengedwe a gulu ndi ndemanga deta pa kuchuluka mayunitsi chidwi, komanso kulembetsa zakuthupi zikupezeka magome. Mukhoza ntchito kudziwa chiwerengero mayunitsi kusanthula pamodzi, kumvetsa kuchuluka kuchitira zizindikiro, koma ndiribe lingaliro la okwana kusanthula pamodzi.

ziwerengero chipangizo

Izi mwachidule zowerengera - izo kuswa mfundo akaphatikiza pa magulu munthu homogeneous. Zagwiridwa osiyana achiyesa kukufikira mu aliyense wa iwo. Komanso kusanthula pa lonse kuchotsedwa. Ntchito ngati kusanthula ndi idzachitika kuphunzira zambiri zokhudza nkhani kapena chinthu, kudziwa makhalidwe amene ali gwero pa izo, kudziwa makhalidwe ndi zithunzi za anthu kusanthula kale.

Izi mwachidule zowerengera ndi grouping ndi ntchito zovuta zokhudza mayunitsi yogawa kuganizira analyte chikhalidwe kapena zachuma ndondomeko (chodabwitsa) m'magulu osiyana.

Komanso, chinali cholinga kuti akonze dongosolo la magawo ena, kudzera amene adzakhala khalidwe la magulu, subgroups Uwerenge mu zochitika funso, akudzizindikiritsa chiwerengero cha mayunitsi mu aliyense wa iwo, komanso zotsatira za kukhazikitsidwa kwa matebulo zowerengera. Chifukwa cha kusanthula zonse ongolankhula wokhutira ndi chikhalidwe cha njira ndi zotsatira ndipo anachita wathunthu zowerengera mwachidule ndi grouping.

malipoti makhalidwe General

A mwachidule chidwi zowerengera anganene molondola ndi zotuluka pa zotsatira.

Pulogalamu ndi dongosolo ino lili enumeration a magulu limene kuchotsedwa kuzipenya ndi kusanthula kale. Malinga ndi ntchito malipoti zowerengera, pulogalamu yeniyeni amusankha.

Zimatengera zotsatirazi:

• kusankha gulu Mbali kulenga machitidwe homogeneous;
• kudziwa chiwerengero cha magulu ndi dongosolo la mapangidwe awo;
• Development a dongosolo la zizindikiro zowerengera kufufuza za chinthu ndi kuchuluka kwa magulu;
• chilengedwe cha mawonekedwe a matebulo zowerengera kupeza mfundo yomaliza.

Features a mitundu yosiyanasiyana malipoti

A chidule cha zochitika za pa limodzi ndi kukafola dongosolo ake kukhazikitsa. Kukutanthauza zambiri pa nthawi ya, aligorivimu, njira ya malipoti, komanso asangalatsi. Onetsetsani kuti mwachindunji malamulo komanso dongosolo limene adzakhala formalized kuonerera zowerengera. Chidule gulu ogaŵikana options centralized ndi decentralized.

Yachiwiri ikukhudza kaphatikizidwe zambiri, pamene kufufuza kumachitika kuchokera pamwamba mpaka pansi pa makwerero kasamalidwe, ndi ikuchitika pa magawo onse a processing mwatsatanetsatane. Iwo ankachita m'munda, mwachitsanzo kuntchito. mumve zambiri amabwera mu maudindo zowerengera zikugwira ntchito m'mayiko onsewa nkhani. Kumene kukonzedwa ndi kutumizidwa ku Russian Committee State Statistics. m'pamene amapeza kukufikira kwa zinthu umoyo ndi zachuma mu dziko.

The centralized zowerengera mwachidule amapereka njira, zokhudza ndende deta onse yaiwisi tinasonkhanitsa pa kafukufuku zowerengera, kuchokera pachiyambi mpaka kumapeto a gulu limodzi.

Malinga kukhazikitsa luso, mwachidule kungakhale Buku ndi makina, zokhudza ntchito makompyuta.

Gawo ndi magulu ndi

Zikomo magawano sayansi ofotokoza m'magulu, mukhoza kupanga mfundo zonse ndi zolondola zokhudza anthu chandamale, komanso njira mosalekeza.

Akamanena za gulu sayansi ankaona mwatsatanetsatane ntchito V. I. Lenina. Iye ananena kuti grouping zowerengera akusowa mabuku kusanthula umoyo ndi zachuma za zochitika mu funso.

Grouping variable zizigwirizana kuti ntchito ikuchitika ndi kafukufuku zowerengera. Malinga ndi chikonzero cha kusamvera kwawo, mukhoza kudziwa umoyo ndi zachuma mitundu ya chododometsa kusanthula kale. Monga chitsanzo kuwala magulu tinganene kuti ntchito yake, zomwe zimagwiritsa chitukuko cha bizinesi ku Russia.

Ndi mothandizidwa ndi magulu zowerengera kuphunzira zonse angathe kuchitidwa. Kupanga magulu homogeneous pamaziko a kugawikana m'magulu osiyana kapena kaphatikizidwe anthu zowerengera anaphunzira mayunitsi molumikizana muyenera mbali zina.

Mitundu ya grouping zowerengera

Mu ntchito zake, mukhoza kuchita ntchito zotsatirazi:

• kuunikila umoyo ndi zachuma mitundu zodabwitsa;
• zochitika kuphunzira kapangidwe ndi kusintha zimene zimachitika iwo;
• Kusankha interdependencies ndi ubale pakati pa zinthu ndiponso makhalidwe amene iwo yodziwika.

ndi mitundu yosiyanasiyana ya magulu zowerengera chiyani? Typological amaganiza anthu kwenikweni ofanana mu variable grouping. Zitsanzo zake akhoza kutchulidwa dziko grouping ndi mtundu umwini. Mu gulu typological kupereka ulemu wapadera kusankha ndi chizindikiritso cha mitundu. Kumanga grouping typological, ntchito makhalidwe kachulukidwe ndi Mkhalidwe.

Achikhalire mbali attributive kugwirizana ndi Kugawilidwa kwanthaka chiwerengero cha magulu ofanana chiwerengero cha gradations wa khalidwe anapatsidwa. Vuto kudziŵa nthawi ya magulu typological kulankhula Kupeleka malire ngati kachulukidwe amene analyte chodabwitsa kusintha khalidwe alipo, anagula nyumba yatsopano.

Mu typological grouping chiwerengero cha magulu anatsimikiza ndi chiwerengero cha mitundu yosiyanasiyana umene ulipo umoyo ndi zachuma. Iwo ali oyanjana ndi kapangidwe, zikuchokera, masiyanidwe makhalidwe kotero akutali structural moiety. Mwachitsanzo, gulu ikuchitika pa chiyeneretso cha wogwila ntchito wonse pa nyumba yosungiramo katundu.

Mtengo wa grouping zowerengera

Ntchito ya grouping zowerengera ndi kafukufuku ndi chizindikiritso cha ubale pakati pa zizindikiro payekha anthu zowerengera. Pofuna kuthana ndi vuto limeneli kumalumikiza magulu anatomical. Iwo amalola kudziwa interdependencies ndi ubale pakati pa kusanthula makhalidwe umoyo ndi zachuma ndi zochitika. Zizindikiro zonse mu zochitika za pa anawagawa mitundu waphindu ndi chinthu. Zoyambazo muli anthu kuti kusintha mchikakamizo cha chinthu zosintha. Ndipo iwo amayembekezera zotsatira za kusintha zinthu mwadongosolo.

Ntchito zofunika ndondomeko ya kumanga magulu mawunikidwe ndi kusankha nambala ya magulu, sipangakhalenso unagwa mu mndandanda wa mayunitsi pansi kuonerera kuphunzira ndi kuganizira za malire awo chovomerezeka.

Kuphunzira zochitika zovuta zachuma ndi chikhalidwe zimaphatikizapo kugwiritsa ntchito magulu kuphatikiza. Iwo ayenera kudziwa okwanira kuyang'anila yekha mu nkhani iyi n'zotheka kumanga chifukwa odalirika.

Pofuna kupeza zinthu mu kusanthula danga ntchito multidimensional grouping. Malinga ndi zomwe ntchito, pali zotsatirazi siyana zowerengera:

• chachikulu, analengedwa pa maziko a mfundo koyamba zopezera Kafukufuku zowerengera;
• yachiwiri, ndiyo chifukwa cha magulu kaphatikizidwe kapena kugawa.

mitundu ya zomangamanga

Pofuna kulimbikitsa magulu a zowerengera, kukatenga mbali makamaka. Ndiye kusankha nambala ya magulu, kukhala kuchotsedwa iwo, ndiye kukonza malire ake. Gulu lirilonse ikuphatikizapo kudziŵa zizindikiro kapena ndalama zawo, kuti ingathandize zimaonetsa magulu kuphunzira. Kusankha ngati mbali ndi mokwanira komanso zofunika nkhani kuphunzira zowerengera. Kuti amakhudza kusokonezeka mayunitsi mu gulu lapadera. pozindikira kuti ikhalebe nditamaliza kuwunika, ndi mwachindunji amadalira grouping Mbali.

Pomaliza

maphunziro Statistical amati aakulu komanso mwadongosolo zatsopano, generalizations, maganizo. M'pofunika kuchita koyamba mwatsatanetsatane kusanthula akamanena chuma bungwe, ndipo kokha pamaziko a anapezazo ndi zotsatira kupeza njira kuthetsa mavuto sakudziwika.

Popeza n'zosatheka kuti zimene tsopano anayamba pa msika zoweta, kafukufuku zowerengera ndi kusanthula anapeza tanthauzo lapadera ndipo tingaphunzirepo. Kuchita kuwerengetsera mwatsatanetsatane komanso mwadongosolo la statisticians masiku ano njira yapadera.

Mwachitsanzo, ndi kusakonda magulu a anthu chandamale cha khalidwe makamaka ntchito mukhoza kupanga nkhani moyenera ntchito kampani, mmene iye ndi moyenerera. Ndi kafukufuku zowerengera mukhoza kupeza pa magawo onse a chinthu akuphunziridwa. Factor mbali bwanji katundu wa chinthu, chifukwa iwo akhoza kuwapeza pa siteji yoyamba mfundo yotsimikizika.

An sitepe yofunika kafukufuku zowerengera ndi gulu ka deta gwero, amene analandira monga kuonerera lapansi. Akatswiri chinkhoswe mu processing analandira kuchokera mabizinezi a zotsatira, ikuchitika generalization, imfomeshoni wokonzeka akuluakulu kuposa ndi akuluakulu.

Chidule amene amachita statistician, ndi ya njira zomwe zingagwiritsidwe ntchito kulemba makhalidwe munthu wa chodabwitsa kukhala kusanthula kudziwa makhalidwe a nkhani kapena zochitika bwanji chitsanzo chitukuko pogwiritsa ntchito zizindikiro zowerengera.

Pamaso kulenga malipoti komaliza, statisticians tsimikizira mudziwe anapereka kwa iwo. Mwachitsanzo, malinga ndi zomwe zinkabweretsa ndi atsogoleri a sukulu, akumanga kutchuka mlingo sukulu. Kuti azipeza zotsatira zinali zoona, osati dummies yekha ntchito pomanga mfundo ku principals matebulo, komanso mwachidule Kafukufuku zoperekedwa kwa makolo, Alumni, ophunzira. maphunziro ofanana imachitika m'munda wa mankhwala, kusonyeza mphamvu ndi khalidwe la yotumikira anthu, kudziwa mlingo wa makonzedwe a chithandizo kwa anthu. Posachedwapa, nkhani zowerengera ntchito zosiyanasiyana. Kuwonjezera kupenda Mwachangu amakampani lalikulu, kuphunzira ofanana ikuchitika dera chikhalidwe, kudziwa makampani bwino ndi mabungwe.
