There are professional data analysts out there who tackle “big data” with complex software, but it’s possible to do a surprising amount of analysis with Microsoft Excel. In this case, we’re using baby names from California based on the United States Social Security Baby Names Database. In this tutorial, you’ll not only learn how to manipulate big data in Excel, you’ll learn some critical thinking skills to uncover some of the flaws within databases. As you’ll see, the Social Security database, which goes back to 1880, has some weird and wonderful anomalies that we’ll discuss.

This tutorial is for people familiar with Excel: those who know how to write, copy and paste formulas and make charts. If you rarely venture away from a handful of menu items, you’ll learn how to use built-in Excel features such as filters and pivot tables and the extremely handy VLOOKUP formula. This tutorial focuses on what’s called “exploratory analysis”, and will clarify the steps to take when you first confront a huge chunk of data, and you don’t know in advance what to expect from it. We’ll also show you how to use these tools to find the flaws in your data set, so you can make appropriate inferences. If you want to improve your Excel chops with some big data exploration, you’re in the right place.

Note: This tutorial uses Excel 2013. If you’re using a different version, you may notice some slight differences as you go through the steps.
