Practice Questions

Data combination merges information from two or more small datasets (tables, caselets, or charts) to answer one question.

Table 1: Product A = 200. Table 2: Product B = 300. Combined sales = 500.

Do not double-count items that appear in both sources unless the question asks for union with overlap.
