Using R to Evaluate College Scorecard

Our company acquired a data file containing over 15,000 rows and 300 columns. We are trying to identify patterns in the data. Where do we begin evaluating such a large dataset? Would Using R be helpful?

Let me answer that question by taking a look at data from the U.S. Department of Education known as the College Scorecard. This organization compiles a wide variety of measures for all colleges and universities in the United States. They track over 300 measures such as:

Average SAT scores for incoming students,
Percentage of students whose parents completed high school, and
Whether the Institution is private or publicly owned.

I originally evaluated this data as part of a capstone course in the Microsoft Professional Program for Data Science. In that class, the overall goal was to identify a subset of these 300 measures that were most useful in predicting a single measure – the average income of graduates. Admittedly, it’s a bit overwhelming to know where to start resolving this sort of problem. You have intuitive hunches that SAT scores or faculty salary might be correlated to the future income of graduates. But how do you systematically evaluate a data set this large?
