Many gamblers believe that it is possible to find a strategy to beat the lottery including selecting numbers that are due to come up or looking for a bias in past numbers. In this paper, we examine sales figures and variations in the number of winners for the various prize levels of a popular Canadian lottery to detect lottery ticket preferences. It was determined that the lottery outcomes conformed well to a random outcome. No evidence of either a bias myth or due to come up myth was found. However ticket popularity indicated a marked preference for the number 7 and low numbers, and the avoidance of high numbers and adjacent numbers. In addition we found a linear and a quadratic relationship between past frequency of the numbers and ticket popularity indicating a belief in both the due to come up and the bias myths. The findings suggest strong non-random preferences in the selection of lottery numbers.
许多赌徒相信，有可能找到一种策略来击败彩票，包括选择即将出现的号码或寻找过去号码中的偏差。在本文中，我们检查了各种受欢迎的加拿大彩票奖级的销售数据和中奖人数的变化，以发现彩票偏好。结果表明，彩票结果与随机结果相符。既没有发现偏差的说法，也没有发现即将出现的说法。然而，彩票的受欢迎程度表明，人们明显偏爱数字 7 和小数字，避免选择大数字和相邻数字。此外，我们发现数字的过去出现频率与彩票的受欢迎程度之间存在线性和二次关系，这表明人们既相信即将出现的说法，也相信偏差的说法。研究结果表明，在选择彩票号码时存在强烈的非随机偏好。
