Is Chuck-A-Luck a Performance Enhancer? A Meta-analysis
Chuck-A-Luck has become a popular theme in many birthday party games. Both children and adults can play the game with a standard deck or playing cards. Then, they place the card(s), into a Chuck A Luck machine. The machine will randomly roll a set of dice and spit out the numbers one through nine. The game is won by the player with the most lucky cards.

When a single piece or small amount of paper or cardboard is rolled around a numbered dice. This is called the "cable tunnel" because it acts as the central point from which the dice can be rolled. Although it may seem like a simple concept, the skill required to master Chuck-A luck is remarkable. Essentially, there are two factors that need to be considered when dealing with Chuck-A Luck. One is the luck and skill of the players. Both of these aspects are dependent on the outcome of previous rolls.

Researchers conducted a joint task to determine the luck of the participants. One group took part in a Chuck A Luck game, while the other did not. Participants were asked to imagine themselves in a relationship with their partner during this joint task context. The questions asked were "Do you feel like you and you partner share the same luck?" and "how would you identify if there are any significant sex differences in outcome evaluation when you and your partner did a Chuck-A-Luck game?" Following the questionnaires, each participant was then asked to describe the way they perceived luck, how the relationship developed, and how the game supported or promoted the growth of the relationship.

There were significant sex differences between the men who answered the questionnaires about intimacy and luck in this joint task setting. Men showed a significant increase in their probability of being the winner when Chuck-A-Lucky was introduced into the social context. Thus, a prior conditioning procedure enhanced the association between winning and intimacy. However, there was no significant association between the extent of winning and intimacy for women. When the Chuck-A Luck factor was introduced to the social scene, women also saw an increase in their likelihood of being the loser.

Thus, both sexes separately showed a positive association between the Chuck-A-Lucky task context and the magnitude of winning but not the extent of winning. Within the context of the questionnaire itself, there was an increase in the number of participants who described themselves as very lucky but not necessarily with a high probability of winning the game. The frequency with which participants described themselves to be very unlucky did not change significantly. This did not support the notion that Chuck-A–Lucky task contexts make players more lucky. The results for the correlation between Chuck-A-Lucky task success and winning are therefore weak. It is therefore not possible to show that people are luckier when they are given a task context.

We then did a main effect to see if the slopes of the distributions wealth and health changed between the Chuck-A-Lucky and the placebo conditions. For this purpose, we repeated all the questionnaire items from the first to the fourth blocks in the original set of questionnaires (one per condition), resulting in a total of eleven such questionnaires. Again, there were significant differences between the slopes of wealth-health relationships between men and women. However, there were significant interactions between these variables for both men & women. The wealth effect was more prominent for women (d =.12, p=.01). It is not clear that Chuck-A-Luck causes greater good fortune but it does show a potential association between the task environment and higher likelihood of positive outcomes.

A chi-square distribution can also be used to examine the association between Chuck-A Luck and health and wealth. We compared the mean log-transformed intercepts values for each participant in the original sample for each value of wealth and health. We then performed an analysis using the Chi-square distribution. One contingency variable was used to indicate whether the participant fell in either the extreme left quadrant or the middle of the distribution. This variable represents the ideal value at the time. For this analysis, the number of pairs of intercepts was kept the same, but the degrees of chi squared before comparison were varied across the 11 questionnaires.

The results showed that Chuck-A-Lucky had a significant effect on the slope of logistic regression slope for logistic outcome. The probability that a participant would be in the extreme right quarter of the distribution increases significantly (p=.01), indicating the effectiveness of Chuck-A-Lucky on the slope of logistic regression slope for the logistic outcome. You could also use a graphical expectancy method to see if the probability of participants falling into the extreme left quadrant is dependent on their task conditions. Logistic regression revealed that Chuck-A Luck had a significant effect on the probability that a participant would be in the extreme left quadrant (a quadratic function having a negative slope). This again indicates that Chuck-A Luck can improve task performance. Further analysis revealed that Chuck-A-Lucky had a significant effect on the slope distribution for the chi square intercept. This indicates that Chuck-A-Lucky improves task execution when the task can be difficult. Luck improves when the task becomes easy.
