Statistics is probably the most used and least understood branch of mathematics in our world today. Statistics is the study of what data says. Anything that you can measure or count is data, and statistics provides the tools you can use to generalize huge amounts of data and predict future outcomes with a high degree of accuracy. Statistics also provides a variety of tests and checks to help you make sure that your generalizations and predictions are valid. The beauty of statistics is that you can apply it to nearly any context, which is why statistics experts are highly sought after to exercise their skills in economics, politics, scientific research, sports and many other industries.
