Statistics


In January 2009, Google's Chief Economist Hal Varian said:

"I keep saying the sexy job in the next ten years will be statisticians. People think I'm joking, but who would've guessed that computer engineers would've been the sexy job of the 1990s?"

Statistics is the development and application of methods to collect, analyze, and interpret data. Data analysis encompasses a variety of statistical techniques such as simulation, Bayesian methods, forecasting, regression, time-series analysis, and clustering.
