Wheel-Bias Detective
Ek wheel ke 3,000 spin ka log jo biased ho bhi sakta hai aur nahi bhi. Lab tools se hot sector dhoondhiye, ya wheel ko fair ghoshit kijiye.
Paanch wheels, paanch faisle. Table par heat map, ±2σ band wala bar chart aur chi-square testlabChi-square testStatistical test jo har pocket ke observed hits ko expected n/37 se compare karta hai. Isse tay kiya jaata hai ki wheel biased hai ya nahi.Poora padhein → hai; sector scan ek point ki keemat par hint ke roop mein uplabdh hai. Wheels mein se ek fair hai.
5 mein se wheel 1 · 3,000 spins
Scoring
9–10: Jagger chahta ki aap wheel par nazar rakhein.
6–8: aap heat map padh sakte hain aur false positive se bach sakte hain.
3–5: aapne mazboot wale dhoondh liye; halka bias aur fair wheel asli test hain.
3 se kam: How to Detect Roulette Wheel Bias aur Sample Size padhiye. Teen hazaar spin mazboot bias ke liye mushkil se kaafi hain aur halke ke liye kaafi nahi.
Ise mushkil kya banata hai
3,000 spin wale fair wheel par har pocketsaamanPocketRotor ke 37 numbered khaanon mein se ek. Doosre naam: slot, cup.Poora padhein → ka expected count 81 hai aur standard deviationganitStandard deviationVariance ka square root; expected value se kisi result ki aam doori.Poora padhein → lagbhag 9, isliye sirf sanyog se kuch pockets ±2σ band ke bahar honge. +40% wala biased pocket lagbhag 113 par baithta hai, lagbhag 3.5σ; +20% par woh lagbhag 97 hai, 2σ se kam, aur akele pocket mein dikhta nahi.

Sawaal
Kyunki bias play ki sabse mushkil skill hot sector dhoondhna nahi hai; woh sector na dhoondhna hai jo hai hi nahi.
Mazboot bias ke liye hazaron; halke ke liye dasiyon hazaar. Jagger ke parivaar ne hafton tak wheels dekhe.
Thodi hansi
Sector dhoondhiye. Ya maan lijiye ki koi nahi hai.
