Data on Unemployment, Exchange Rate, Interest Rate and Inflation Rate

Statistics is the science of collecting, analyzing and making inference from data. Statistics is a particularly useful branch of mathematics that is not only studied theoretically by advanced mathematicians but one that is used by researchers in many fields to organize, analyze, and summarize data.  Statistical methods and analyses are often used to communicate research findings and to support hypotheses and give credibility to research methodology and conclusions.
