Data analysis is a part of the Business Intelligence. It can be used for many purposes: confirmation of a hypothesis, forecasting, or discovering new features in data. We are all surrounded by information and being able to see the bigger picture can help us make an informed decision. In the past, many business decisions used to be made based on a hunch, because no one actually could get data from thousands of people at once. Now, with the internet, you don’t even have to make surveys to get your market research. The information is out there and all you need to do is make an analysis and draw the conclusions.
