The range of 84.0 suggests a significant spread between the lowest and highest jersey numbers. However, the sample standard deviation of 26.3 indicates that, despite this range, the majority of the numbers are relatively close to the mean. Since the standard deviation is large compared to some jersey numbers, it suggests that there's substantial variability in players' numbers, leading to the conclusion that jersey numbers on a football team vary much more than expected. While jersey numbers can be seen as nominal data, they also carry meanings related to player positions or roles, influencing how coaches might organize their teams. Thus, even though they replace names, analyzing jersey numbers can provide insights into team composition and strategy.
