Verified step by step guidance

1. Understand that consumer preferences refer to the tastes and choices that guide consumers when deciding what goods and services to purchase.
2. Recognize that analyzing government tax policies, calculating the unemployment rate, and measuring total output of firms provide macroeconomic or supply-side information, but do not directly reveal individual consumer preferences.
3. Focus on data that reflects actual consumer behavior, such as what products consumers choose to buy and how much they spend on them, since this directly indicates their preferences.
4. Collect data on consumer choices and spending patterns through surveys, market research, or sales data to observe which goods and services are favored.
5. Use this data to infer preferences by analyzing trends, frequency of purchases, and spending amounts, which helps economists understand what drives consumer decisions.
