Abstract

The case provides data gathered from 18 hours of play at a single roulette wheel in a Nevada casino. Data include the frequencies of each of the 38 sectors over 904 spins and frequencies of the 22,527 "straight-up" bets placed. Summary data is also available on how bettors react to streaks in even-money outcomes—allowing one to test for the gambler's fallacy. The case is used in an introductory course on data analysis. The data came from Croston and Sundali (2005).

The Roulette Wheel

This case examines data gathered from surveillance video of 18 hours of play at a single roulette table in a large casino in Reno, Nevada. During the 18 hours, casino employees spun the wheel 904 times, and researchers carefully recorded the outcomes of each spin as well as the relative frequencies of the 22,527 bets placed.

Roulette

As is the case for most American roulette wheels (Figure 1), the wheel was divided into 38 equal-sized sectors numbered 1 to 36 plus 0 and 00.
