Using Group Shuffle

Group shuffle enables you to perform a shuffle within discrete units, or groups, where there is a relationship among the members of the group. Consider the case of shuffling the salaries of employees. Table 19-4illustrates the group shuffle mechanism, where employees are categorized as managers (M) or workers (W), and salaries are shuffled within job category.
