“SQL is an important tool for any data scientist” — is my entry for the understatement of the year. As information jockeys, data scientists use SQL to query the data they will need for analysis from established databases. Depending on the demands of your position as a data scientist, you…

“There are two kinds of people in this world…” Are words we’ve all heard before, typically from an elder relative trying to make sense of some bigger picture for you. As cliche as the statement is, demographic information — identifiers which tell us something about the members of a population…

Once one has a good understanding of the data they have to work with, they next need to decide what they aim to answer with this information. Understanding the problem at hand is part of the Business Understanding step in the Data Science Process. A business question with a data…

It is widely reported that over 80% of a data scientist’s time is spent cleaning and engineering data. Great effort is put into preparing the information that will feed a data scientist’s models. …

Why it is important to know what your end goal is… When I set out on a two month journey to complete my capstone project for Flatiron School, effectively ending the first chapter of my story to become a data scientist, I knew that I wanted to have something more…
