Khalidwe la koyefishienti a kusintha

Pa kafukufuku , ambiri akukumana ndi masiyanidwe a khalidwe anaphunzira mayunitsi munthuyo anthu, nichipita ndi ulemu ndi phindu zina, ndiko, ndi kusintha kwake. Ndi zimenezo, ndiye onetsetsani kuti kuganizira kuti mfundo yodalirika pa kukhazikitsa maphunziro a sayansi.

Akatswiri ambiri, kufuna kwa imeneyi mfundo za chizindikiro ndi, nthawi zambiri amachita mawu mtheradi ndi wachibale. Mbadwo Wotsirizira, lofalitsidwa koposa koyefishienti a kusintha, zimene zinachitikira variable yodziwika yachibadwa yogawa pachilichonse muyezo ndi anthu. chizindikiro Zimenezi zimathandiza kuti asankhe digiri ya kupezeka adzakhala ndi mtengo wa mayeso chizindikiro, si powasamalira lonse ndi unit wa muyeso.

The koyefishienti a kusintha kuchita masamu ndi kugawa ndi kupatuka muyezo kwa masamu limatanthauza mtengo wa variable ndi, anasonyeza kuti anthu a. The chifukwa cha mawerengedwe ichi amagwa mu osiyanasiyana kuchokera ziro kwa osawerengeka, kuwonjezeka ndi kuwonjezeka khalidwe kusintha. Ngati mtengo analandira ndi zosakwana 33,3% - ofooka kusintha khalidwe. Ngati kwambiri - amphamvu. Zikatero, deta ankafufuza akonzedwa si yunifolomu, phindu lake pafupifupi chimatengedwa ngati atypical, choncho sangakhale chizindikiro ambiri. Choncho, kwa anthu anapatsidwa iyenera kugwiritsidwa ntchito zizindikiro zina.

Tikumbukenso kuti koyefishienti a kusintha, si kuchuluka kwa pachilichonse khalidwe, komanso ntchito yayendera poyerekeza. Mwachitsanzo, amagwiritsidwanso ntchito ngati n'koyenera kuyerekeza makulidwe a fluctuation mu zopereka khalidwe limene mtengo zikutanthauza kufunika masamu ndi osiyana. Mu nkhani iyi, kuwanditsa wa deta salola cholinga ziyenera a mfundo zinazake. The koyefishienti a kusintha limasonyeza masiyanidwe wachibale wa variable, ndipo kotero angakhale wachibale muyeso wa kusinthasintha mtengo wa chizindikiro cha akuphunziridwa.

Komabe, pali zoletsa zina. Makamaka, kuti aone digiri ya fluctuation mfundo chizindikiro kungakhale kokha kwa khalidwe makamaka, ndipo ngati ndalama ali zikuchokera makamaka. Pankhaniyi, Kuyanjana pakathi pa zolozerazi zingasonyeze onse amphamvu ndi kusintha ofooka. Izi zili choncho ngati zizindikiro zosiyana kapena maphunziro amene amachitika zopereka zosiyana. Chonchi chifukwa ndi kwaiye zochita za zifukwa cholinga kwambiri, ndipo zimenezi ziyenera amaonanso pa processing deta experimental.

The koyefishienti a kusintha chimagwiritsidwa ntchito pochita zowerengera processing deta ndi ntchito zosiyanasiyana za sayansi. Kwenikweni, ntchito mwakhama ntchito yayendera a magawo a kusinthasintha mu chuma Chaanthu. Pankhaniyi, mlingo ntchito n'zosatheka choncho m'pofunika amayang'anitsitsa masiyanidwe a zosintha kuti amatha kusintha chizindikiro chawo. Ndipotu, ngati chifukwa cha mawerengedwe pachithunzichi makhalidwe index adzakhala analandira: mwina adzakhala ochepa, kapena adzakhala ndi chizindikiro chochotsera. Zikatero m'pofunika kufufuza kulondola kwa kuwerengetsera lapansi.

Choncho, tingathe kunena kuti kusintha koyefishienti - ndi chizindikiro kuti adzalola kuti aone mlingo wa kupezeka ndi masiyanidwe wachibale wa ndikutanthauza. Kugwiritsa ntchito chizindikiro ichi limasonyeza mfundo zofunika kwambiri poganizira kukwaniritsa zolinga zawo ndi kukwaniritsa ntchito zofunikira.
