Muchiedza Statistical Hypotheses: mukuru pfungwa

Pfungwa - chimwe chezvinhu zvinokosha kukura sayenzi uye kwesayenzi mberi. The zvichiguma zvaanorumbidza pamusoro mananara siyana uye chokwadi, pfungwa iri chaizvoizvo yokungotaura kubvuma. The zvakadzama kudzidza zvinhu izvi uye mananara zvakafanira kuongorora mashoko tsvagai zvekungofungira. Dzakashandiswa kuti kuedza zvekungofungira izvi zvinofanira kuva hwaro nesayenzi. Nemamwe mashoko, kuva nemhaka zvakawanika kana zvidzidzo kwakavakirwa akadzika midzi nenheyo yesayenzi.

Kuti tizive kuvimbika pakati yokungotaura zvekungofungira pane Statistical pfungwa yokuedzwa. Nzira iyi inosanganisira kushandisa imwe Statistical chokuratidza, anofambirana kupinda zvinonyatsorehwa pfungwa redunhu, wakaumbwa kuwana imwe mhando basa maererano pakutsvakurudza zvabuda kana zvakawanika (bvunzo nhamba). Kwakadaro Statistical pfungwa kunovhenekwa unokubvumira kuita chisarudzo chokupedzisira pamusoro kuvimbika pamusoro yokungotaura zvekungofungira.

Process Statistical ongororo kunowanzoguma kudiwa mukuronga uye kuedza imwe yokungotaura zvekungofungira pamusoro vanhu vakadzidza variables kana akazvimirira parameters. Kuenzanisa pfungwa iyi iripo date yokuenzanisira, zvichiteverwa tinyatsonzwisisa ukuru rakavimbika goho, uye rakatangwa nokushandiswa zvimwe Statistical nzira, anonzi - Statistical pfungwa kunovhenekwa.

Mukutonga Statistical hypotheses anofanira kunzwisiswa nekuve yokungotaura zvekungofungira pamusoro pezvakaita uye parameters ari kugovera vamwe anongoitika variables, izvo zvingazivikanwa pasi rokuongorora, achitungamirirwa migumisiro pakudzidza uri chero Statistical zvakabudiswa. Nemamwe mashoko, nhamba pfungwa akadana zvekungofungira pamusoro ehupfumi pakati vanhu, kuti aedze kuti unogona kushandisa Statistical zvakabudiswa Data. Saka, zvinovawo zvinobvira kuedza pfungwa wakanyatsojeka pamusoro paavhareji vanhu uye vamwe tsvagai tsika.

Statistical pfungwa yokuedzwa, zvinoreva chiri kuti pahwaro iripo Statistical Data kusimbisa kana kuramba yokungotaura kubvuma shoma ngozi kudzivirira chikanganiso kana chikanganiso unoshanda chaizvo uye nzira yakakurumbira kutsvakurudza kwesayenzi. Pfungwa kunovhenekwa rinoitwa pasi mitemo zvachose kunorondedzerwa.

Nguva dzose yeuka kuti Statistical pfungwa kunovhenekwa iri probabilistic zvakasikwa. With nzira iyi unogona kutsanangura mune digital (chikamu) mashoko, mukana yokuita zvakaipa kusarudza kana nhema mhedziso pamusoro kududzirwa migumisiro Statistical kudzidza kutanga kana chiitiko. Kana fungidziro kwokukanganisa kana chikanganiso chiri kunyora nezvavo, kuti Statistical ukama dzaona kudzidza chokwadi kana rakadai rinogona kushandiswa zvinangwa zvinoshanda pamwe shoma mukana kukanganisa.
