Explanation
This question tests understanding of data types and practical application of statistical analysis. The answer differentiates structured and unstructured data using textbook definitions and examples. The dataset creation follows the tabular format shown in Table 7.1 of the context. Statistical techniques like calculating profit margins, total sales (multiplying price × quantity as mentioned in context), and range are applied to make meaningful comparisons for each sub-part.
