Quizplus · Accepted Answer

Economic conditions are external sources of marketing data as they are influenced by factors outside the company's control, such as the overall state of the economy or changes in government policies. The other options - sales forecasts, inventory levels, purchase requests, and prices of products - are all internal sources of data as they pertain to the company's own operations and performance.
