Mack-the-Auditor Gets Audited! Part 1

Review ACL logUsually, I’m the one doing the auditing, but this time, I (Mack) was the one who was audited.

It was a great experience for me.

Well, sort of. No one likes being audited (ahem). But it gave me a fresh perspective of how others feel when I audit them.

Before You Analyze Data

Before you start analyzing data, you need to 1) know you have the right data, and 2) understand the data and the process that produced it.

This post assumes, of course, that you already accomplished some of the hardest tasks already: figuring out what data you need, where to get it, and actually getting the data. Good luck with that. :)

How to Profile Data

Before you analyze data, you should profile it.

Otherwise, your analysis may not be too broad, too narrow, or you may miss some important insights or errors.

This post is part of the Excel: Basic Data Analytic series.

Data profiling is developing a profile of your data, just as facial profiles of a person, taken from various angles, helps you size up a person’s nose, identify whether his chin is sagging, and how far apart the person’s eyes are.
