Wheel-bias detective
A log a 3,000 spin fram a wheel weh maybe bias, maybe no. Use di Lab tool dem fi find di hot sector, or seh di wheel fair.
Five wheel, five verdict. A heat map, a bar chart wid di ±2σ band an a chi-square testlabChi-square testStatistical test weh compare di hit dem yuh see inna evry pocket wid di n/37 yuh fi expec. Dem use it fi judge if a wheel bias.Read di whole ting → deh pon di table; yuh can get a sector scan as a hint, but it cost yuh a point. One a di wheel dem fair.
Wheel 1 outta 5 · 3,000 spin
Score
9–10: Jagger woulda waan yuh fi watch di wheel.
6–8: yuh can read a heat map an yuh nuh fall fi a false positive.
3–5: yuh find di strong one dem; di subtle bias an di fair wheel a di real test.
Unda 3: read “Ow fi find bias inna a roulette wheel” an “Ow big di sample size fi be”. Tree thousand spin barely enough fi a strong bias, an it nuh enough fi a subtle one.

Cause di hardest skill inna bias play a nuh fi find a hot sector; a fi nuh find one weh nuh deh deh.
