Kuchema kwelisondvo le-roulette

Lisondvo le-roulette lelichemile litsandza leminye imigodzi ngenca yesici sesakhiwo: i-fret lehlephukile, i-rotor lengalingani, imigodzi lesiyagugile. Kuchema kwelisondvo le-roulette kukhona futsi sekuke kwasetjentiswa. Bumatima kutsi lisondvo lelingachemile ngalokuphelele likhicita “tinombolo letishisako” njalo, ngako umbuto awusiwo nanini kutsi inombolo iyashisa yini, kodvwa kutsi sakhiwo sonkhe singalingani kakhulu yini kunaloko inhlanhla lekuvumelako.

1. Tsatsa sampula yelisondvo lelingachemile

Kujikeleta lokudvonswe elisondvweni lelilingisiwe lelingachemile nhlobo. Shintja bukhulu besampula bese ubuka umgodzi loshisa kakhulu.

Libha ngalinye ngumgodzi ngekulandzelana kwelisondvo. Umugca lonemachashati linani lelilindzelekile, n/37. Libhande lelifiphele lingu-±2 wekuphambuka lokujwayelekile: elisondvweni lelingachemile cishe umgodzi munye kulamashumi lamabili utawuphuma ngaphandle kwalo ngenhlanhla nje.

3. Kuhlolwa kwe-chi-square

Kuhlola kuhlanganisa kutsi umgodzi ngamunye ukhashane kangakanani naloko lokulindzelekile, kuphindvwe ngako ngekwako futsi kulinganiswe. Elisondvweni lelingachemile lesamba silandzela kusakateka kwe-chi-square lokunemazinga enkhululeko langu-36; i-p-value lengaphansi kwa-0.05 ngalokujwayelekile ibitwa ngekutsi ibalulekile ngekwetibalo.

χ² = Σ (Oᵢ − Eᵢ)² / Eᵢ Eᵢ = n/37 df = 36

Sicwayiso ngebukhulu besampulaNgaphansi kwa-kujikeleta lokungu-1,000 kuhlola cishe akunawo emandla ekutfola kuchema lokungenteka ngempela, futsi umphumela “lobalulekile” nga-p < 0.05 utawenteka ngenhlanhla ka-1 kuwo onkhe emasampula langachemile langu-20 lowabukako. Kuhlola emasondvo lamanyenti, noma kuphindza kuhlola lisondvo linye kuze liphumelele, kucinisekisa imiphumela lengasilo liciniso.

4. Kujikeleta lokungakanani lobekungakudzinga

Kujikeleta lokudzingekako kute kutfolakale umgodzi munye lophuma kanyenti kunanga-1/37, ngelizinga le-5% ngakulinye licala nangemandla e-80%. Umgodzi lophuma ka-1 ku-35 esikhundleni sa-1 ku-37 ungaba yinzuzo lenkhulu yemdlali, futsi kudzinga emashumi etinkhulungwane ekujikeleta lokubhaliwe kute kucinisekiswe.

Indlela yekusebenta

Kutsatsa sampula. Kudvonsa lokulinganako emigodzini lengu-37 kusetjentiswa sikhiciti lesinembewu (mulberry32, imbewu 99), ngako likhasi lingaphindvwa.

Kuhlola. Kuhlolwa kwe-chi-square kwaPearson kwekuvumelana, emazinga enkhululeko langu-36, i-p-value levela ku-gamma function lengakapheleli lelinganisiwe.

Emandla. Kulinganisa kwe-normal kuhlolwa kwesilinganiso sinye, α = 0.05 ngakulinye licala, emandla 0.80.

Bubanti. Kutfola ngetibalo kuphela. Timbangela tesakhiwo nekuhlatiya ngetigaba (esikhundleni sekuhlatiya ngemigodzi) kuchazwe ku-Kuhlatiya tigaba.

Lokuhlekisako

Lisondvo lelingachemile lenta tinombolo letishisako onkhe emabusuku. Kufakazela kuchema kudzinga emashumi etinkhulungwane ekujikeleta.
