Kuhlatiya tigaba
Emaphutsa esakhiwo atsintsa imigodzi lengumakhelwane ndzawonye, ngako hlola tincenye telisondvo, hhayi tinombolo letitodvwa kuphela.
Hlanganisa imigodzi lengu-37 ibe tigaba letilandzelanako bese uchatsanisa kushaywa lokubonwe nalokulindzelekile esigabeni ngasinye. Kuchema kwangempela ngalokuvamile kuvela njengesigaba sinye noma letimbili letisedvutane letishisako etisampuleni letitimele.

Kungani tigaba
Kuhlolwa kwemgodzi munye kunematfuba langu-37 ekunika umphumela wemanga, neluphawu lolubutsakatsaka kunye nanye. Kuhlolwa kwetigaba kunematfuba lasitfupha neluphawu loluhlangana kuyo yonkhe imigodzi lengumakhelwane. Kuyavumelana futsi ne-physics: lisondvo lelitsambekile lenta kutsi libholatinsitaLibholaLibhola lelincane leliphoswa emzileni lihamba ngakulolunye luhlangotsi kune-rotor.

Tigaba letihambako
Imingcele lemile ingahlukanisa incenye leshisako emkhatsini wetigaba letimbili futsi iyenciphise. Lenye indlela lesekelako ishelelisa lifasitelo lemigodzi lengu-k tungeleta lisondvo, ibala z etindzaweni tonkhe letingu-37, bese ifuna lelikhulu kakhulu. Linani lelikhulu kakhulu kumanani e-z langu-37 lahlobene nangabe lisondvo lingachemile ngalokuvamile lingaba ngu-2.2 kuya ku-2.5, ngako linani lelikhulu lelifasitelo lelihambako lelingaphansi kwa-2.5 ngumsindvo, futsi umkhawulo wekunaka ngako uphakeme, cishe ku-3.5.
Kusuka esigabeni kuya ekubhejeni

Umehluko nguhhafu wephesenti, yingako kuwucinisekisa kudzinga emashumi etinkhulungwane tekujikeleta.
Sihlatiyi
Sihlatiyi sekuchema kwelisondvo le-roulette kulelisayithi semukela luhlu lwekujikeleta, sibala i-chi-square, bese sikhombisa lisondvo njengemephu yekushisa lenemanani e-z etigaba, ngekwehlukanisa lokungenhla njengalokumisiwe. Siphindze sihlanganise idatha yakho kute sikhombise kutsi letibalo letifanako tibukeka njani nangabe lisondvo lingachemile, lokulikhambi lelisheshako lekubona emaphethini lapho angekho khona.
