Labantu kwezibalo

Izibalo - isayensi etadisha imihlola mass ezenzeka emphakathini ngokuya izinga nobungako bezithelo. Lokhu nje ingenye izincazelo yamukelwe. Kukhona umbono phezu kwayo, njengoba isayensi esakheka izindlela kwezibalo ucwaningo ezindaweni ezehlukene.

Eliphawuleka kakhulu futhi evamile izici, izakhiwo kanye nomlingiswa imihlola kanye lezinto ezikhona elibanzi kubonise imiqondo ethile noma izigaba. Ngosizo lwabo, lokhu isayensi study into siqu. Omunye salezi zigaba kuyinto aggregate kwezibalo. Lena inombolo enkulu imihlola obuhlukahlukene ezikhona space kanye nesikhathi. Bonke bangabangasokile lonelubanjiswano futhi kunezimpawu, ulethe eduze noma ezahlukene kubo.

labantu Statistical libhekene Izakhiwo ezilandelayo:

1. Indecomposability. Lapho avele noma anyamalale tincenye letitsite labantu kwezibalo, isizinda eliphezulu kwalo asibhubhi. Ngokwesibonelo, izici umphakathi abafundi 'ayishintshi yokuthi njalo ngonyaka zezikhulu zayo ngokufaka freshmen futhi abathweswe iziqu sebehamba.
2. Ukufana. labantu Statistical kuhlale okungenani ngento eyodwa ngoba wonke izakhi zalo. Ngesikhathi esifanayo, lesi sici asikho ngabo okufanayo. Lesi sici singahle namanani ahlukene for amayunithi ezahlukene. Umbuto kutsi labantu izibalo eyohlobo, nokuvumelana ngesikhathi uphenyo. Futhi kuncike impahla, ngokuyinhloko emigomweni ngawo eliphethwe ngayo.
3. Ukuguquguquka. Le mpahla kubaluleke ngaphezu owedlule ezimbili. It kuzibonakalisa kanje: ngesikhathi Ukuqeda ngesinye sezinqumo kwenye labantu kwezibalo sishintsha ambalwa sici amagugu. Kungaba for zonke izingxenye okufanayo. Kulokhu, ukuze uthole umqondo walokho labantu kwezibalo, awukwazi ukufunda ngokugcwele, futhi sicabangele isici abamelwe eyodwa kuphela. Okuvela ukushintshashintsha kuthinta lahlukene izimbangela nemibandela. okwatholakala yabo, ukuchaza isiyalo ngokwezimali okuhilelekile. A izibalo kuphela ihlola quantitatively indlela ngayinye kuthinta ukushintshashintsha imbangela trait ethile. Ulwazi mayelana lokhu kusiza ukwenza izinqumo zokuphatha ilungelo.

aggregate Statistical zihlukaniswe amaqembu amaningana:

1. Labo ukuthi ukudala ukuphila. Kakade akha ubunye, kungakhathaliseki ngaphansi uphenyo noma cha. Isibonelo, lokhu iqoqo amabhizinisi ezimbonini edolobheni, isiqalo nesigcino abasebenzi babo. Empeleni ngibabheka njengomndeni khona, angase kulinganiswa.
2. Amaqembu ukuthi akhiwa ngokuqondile ukuqhuba ucwaningo. Lokhu, isibonelo, iqoqo lezibalo abafundi abathile amaphephabhuku.
3. isethi yezinto. Lokhu iqoqo stochastic (ezifana izindikimba zasezulwini ezikhona Umthala). Okungukuthi, bamane nje kufanele acabange.

Noma yimuphi labantu kwezibalo nakunoma yisiphi amaqembu amathathu inezici isici. Can ahlukanisa kubo ngenxa yezizathu eziningi.

Ngokwesibonelo, kuye ngokuthi uhlobo izimpawu Inkulumo yilezi:

1. Okuchazayo (isibaluli). Basuke uzwakalise ngamazwi nangezenzo (isibonelo, imfundo, uhlanga, ubulili). Lezi zici avumela ukuba afingqe bangaki amayunithi ukuba zithole noma yini ukubaluleka.
2. Quantitative. Isilinganiso - zezinombolo (isib, ubudala, ubude inkonzo, inani azuze noma ukulahlekelwa, njll). Lezi zici futhi uvumele ukuba afingqe isibalo salabo amayunithi ukuthi zinenani ezithile, futhi inani eliyisilinganiso noma Imininingwane ngokuhlukile lokubolekwa yabo.
