Getting Started with Haskell Data Analysis

Using SQLite3 SELECT and the DescriptiveStats module for descriptive statistics

This section will serve as our review of the SQLite3 SELECT queries and our DescriptiveStats module. In this section, we're going to take a look at loading data from our MovieLens dataset into an IHaskell notebook.
