The breadth of business, educational, and organizational information in existence today is absolutely staggering. Organizations the world over rely on this information to make sound decisions regarding all manner of affairs. But with the amount of available data growing on a daily basis, the ability to make sense of all of that data is becoming more and more challenging. Fortunately, the days of performing calculations and analyzing data on paper are pretty much gone. Imagine, if you will, having to calculate what percentage of your organization's sales occurred in one small town in, say, Brazil. If your organization operates in multiple countries and generates billions of dollars in revenue annually, it could take a lifetime to isolate the exact figures you need and then compare those to the rest of your revenues. Who has that kind of time? This is exactly where the power of Excel can help.
