It helps you answer why questions like " are there places in the United States with test scores that are consistently above the national average?" or " are there areas of the city with such high rates of residential burglary?"
You might use regression analysis to explain childhood obesity, for example, using a set of related variables such as income, education, and accessibility to healthy food.

If, for example, you discover that childhood obesity is lower in schools that serve fresh fruits and vegetables at lunch, you can use that information to guide policy and make decisions about school lunch programs. Likewise, knowing the variables that help explain high crime rates can allow you to make predictions about future crime so that prevention resources can be allocated more effectively.

so, always look for:
do you need to the of based on the of a based on given data
