You have probably heard that this is the era of “Big Data”. Stories about
companies or scientists using data to recommend movies, discover who is
pregnant based on credit card receipts, or confirm the existence of the
Higgs Boson regularly appear in Forbes, the Economist, the Wall Street
Journal, and The New York Times. But how does one turn data into this type
of insight? The answer is data analysis and applied statistics. Data analysis
is the process of finding the right data to answer your question, understanding
the processes underlying the data, discovering the important patterns in
the data, and then communicating your results to have the biggest possible
impact. There is a critical shortage of people with these skills in the
workforce, which is why Hal Varian (Chief Economist at Google) says that
being a statistician will be the sexy job for the next 10 years.
This course is an applied statistics course focusing on data analysis.
The course will begin with an overview of how to organize, perform, and
write-up data analyses. Then we will cover some of the most popular and
widely used statistical methods like linear regression, principal components
analysis, cross-validation, and p-values. Instead of focusing on mathematical
details, the lectures will be designed to help you apply these techniques
to real data using the R statistical programming language, interpret the
results, and diagnose potential problems in your analysis. You will also
have the opportunity to critique and assist your fellow classmates with
their data analyses.
