Data plays a crucial role in decision-making because it can reveal relationships between different quantities. Often it is useful to break data down into additional categories. For instance, a business identifies its best-selling product and then breaks that information down further to find the age group that is most likely to purchase that product.

Think about a situation when you needed to analyze data. Would it have been helpful to further break down that data? How does breaking down data help you make a decision related to the situation?
