Ku Tsheka ka Vhilwa ra Roulette

Vhilwa ra roulette leri tshekeke ri tsakela tikhamara tin'wana hikwalaho ka xihoxo xa xiviri: ribiya leri ntshunxekeke, rotor leyi nga ringaniki, tikhamara leti dlayekeke. Ku tsheka ka vhilwa ra roulette ku kona naswona ku tshame ku tirhisiwa. Ku tika hileswaku vhilwa leri nga tshekiki nikatsongo ri humesa “tinomboro to hisa” minkarhi hinkwayo, hikwalaho xivutiso a hi xa leswaku nomboro yi hisa, kambe i xa leswaku xivumbeko hinkwaxo xi tsheke ku tlula leswi xitshuketa xi swi pfumelelaka.

1. Teka sampulu ya vhilwa leri nga tshekiki

Marhendzeleko lama kokiweke eka vhilwa leri simuleriweke leri nga tshekiki nikatsongo. Cinca vukulu bya sampulu u languta khamara yo hisa ngopfu.

2. Leswi voniweke na leswi languteriweke

Bara yin'wana na yin'wana i khamara hi ku landzelelana ka vhilwa. Layini ya swiphemu i nhlayo leyi languteriweke, n/37. Bandi leyi dzwihaleke i ±2 wa ku hambuka loku tolovelekeke: eka vhilwa leri nga tshekiki kwalomu ka khamara yin'we eka makume mambirhi yi ta huma ehandle ka yona hi xitshuketa ntsena.

3. Xikambelo xa chi-square

Xikambelo xi hlanganisa leswaku khamara yin'wana na yin'wana yi le kule ku fikela kwihi na leswi languteriweke, hi ku andzisa hi yoxe na ku pima. Eka vhilwa leri nga tshekiki ntsengo lowu wu landzela ku hangalaka ka chi-square loku nga na tidigiri ta ntshunxeko ta 36; ntsengo wa p wa le hansi ka 0.05 hi ntolovelo wu vuriwa swa nkoka hi xitatistiki.

χ² = Σ (Oᵢ − Eᵢ)² / Eᵢ Eᵢ = n/37 df = 36
n = 370 · E = 10.00 · χ² = 32.80 · p = 0.622

Xilumkiso xa vukulu bya sampuluEhansi ka kwalomu ka marhendzeleko ya 1,000 xikambelo xa kala matimba ku kuma ku tsheka loku nga ntiyiso, naswona mbuyelo “wa nkoka” eka p < 0.05 wu ta humelela hi xitshuketa 1 eka tisampulu ta 20 leti nga tshekiki leti u ti langutaka. Ku kambela mavhilwa yo tala, kumbe ku kambela vhilwa leri fanaka nakambe ku fikela ri hundza, swi tiyisisa mimbuyelo ya mavunwa.

4. Marhendzeleko mangani u nga ta ma lava

Marhendzeleko lama lavekaka ku kuma khamara yin'we leyi humaka ngopfu ku tlula 1/37, eka xiyimo xa 5% xa tlhelo rin'we hi matimba ya 80%. Khamara leyi humaka 1 eka 35 ematshan'wini ya 1 eka 37 a yi ta va vuyelo lebyikulu eka mutlangi, naswona swi lava makume ya magidi ya marhendzeleko lama tsariweke ku swi tiyisisa.

1 eka 35+2.9%69,4611,737 h

Ku tiyisisa ku tsheka swi vula ku tsala marhendzeleko vusiku na vusiku, makume ya magidi ya wona.

Maendlelo ya Ntirho

Ku teka sampulu. Ku koka loku ringanaka eka tikhamara ta 37 hi xitumbuluxi lexi nga na mbewu (mulberry32, mbewu 99), leswaku pheji yi kota ku phindiwa hi ndlela yin'we.

Xikambelo. Xikambelo xa chi-square xa Pearson xa ku fambelana (goodness of fit), tidigiri ta ntshunxeko ta 36, ntsengo wa p wu huma eka regularized incomplete gamma function.

Matimba ya xikambelo. Ku tshinelelana ka normal eka xikambelo xa xiphemu xin'we (one-proportion test), α = 0.05 hi tlhelo rin'we, matimba 0.80.

Vuanami. Ku kuma hi xitatistiki ntsena. Swivangelo swa xiviri na nxopaxopo hi swiphemu (ematshan'wini ya hi tikhamara) swi hlamuseriwile eka Nxopaxopo wa Swiphemu.

Ku hlekisa katsongo

Vhilwa leri nga tshekiki ri humesa tinomboro to hisa vusiku byin'wana na byin'wana. Ku kombisa ku tsheka swi lava makume ya magidi ya marhendzeleko.
