Dealing With Dirty Data in Excel (continued).

In my last post, we explored the organizational structure of many large companies and how this pertains to one's duties as a fledgling data analyst.

Dealing with Dirty Data in Excel

Cleaning data Excel in the absence of tools designed to do so.

In my last post, we discussed what separates a true analyst (read: technical) from a project manager wearing the mask of an analyst like some Scott Snyder era Joker (I figure that there's a solid overlap between fans of comic books and fans of the real world application of data. Note that this is a study with an N = 1

Doing the Excel Data Dance

Taking a step back to reflect on the problems Excel intends to solve.

If you've been reading along, over the last several posts you've learned the two major skills that any self-respecting Excel jockey counts as their go-tos: the ability to lookup (remember, I'm partial to index-match, but if you learned VH lookup, ride that until you crash your system) and the ability to pivot.

Adventures in Excel: Power to the Pivot

Power up your Excel Pivot Tables with these pro moves.

The Art of Excel Pivot Tables

Pivot complex Excel spreadsheets to summarize your data.

As previously discussed, the entry level data professional (coming from a background other than statistics, math, or computer science) consists of two keywords: The ability to lookup and the ability to pivot.

Excel Showdown: Index Match vs. "The Lookups"

Learn to hate V-Lookups and H-Lookups in favor of Index Match.

You may have picked up in my last post that some fellow wizards (of which I now consider you if you've mastered Index-Match, and you've activated developer mode) who may have started learning Excel prior to 2007 may drop the phrase "lookup;" generally in the context of "V-Lookup" (or perhaps "H-Lookup" if they're working with data that was formatted by

How I Stopped Worrying and Learned to Love the Formula

Learn to define and utilize Excel formulas.

In my last entry, I took you on a journey to unlock the secrets of Excel; essentially making you a spreadsheet wizard. However, one important thing to remember at work is that a company can't function if it's comprised of only wizards (tell me to my face that Hogwarts was a functioning school!)
