Consider business analytics. It is all about the quality and quantity of the data. No data means no decisions. Bad data means you may make bad decisions. You work for a business that sells surfboards (it is California after all!). The boss asks you to aid in determining what the next best selling surf board will be. Where do you start? How do you determine if the data you find is valuable? How often will you check it for changes? Will you gather it yourself or hire a company to gather it? What are the 'must haves' in your criteria for using the data?
