Data analytics is iterative like the sky is blue… what does that actually mean? I get the sense from many new analysts that they’ve spent a decent amount of time looking through the data and trying different things, and they get that things aren’t linear, but they still ...

Getting into analytics can be overwhelming: so many tools to learn and techniques to apply. Advancing into Analytics is a great start made even better with practice and supplemental knowledge. That’s where a class can come in handy, and I’m excited to share that I’m working on ...

Advancing into Analytics is a wide-reaching a technical book: starting with the foundations of analytics of Excel, readers are introduced to data manipulation, visualization and hypothesis in both Python and R. Learning all this in one book is possible because of what Excel users already know about working with data: ...

I have written about Python, the open source programming language, throughout the blog. However, I understand that my readers, traditionally Excel users, may not have Python installed on their machines or done much programming before. The purpose of this resource guide, then, is to serve as a “mission control” for ...

If you work with data, you need a good laugh every now and again. And nothing says “Internet break” like a good meme trawl. Now, I like a meme just like the next guy, but I have trouble thinking of my own. One (possible) exception is in the category of ...

If you’ve visited my blog before you’ll know that I see Excel as a valuable slice of the data analytics stack. In fact, I think it’s the best way to learn analytics. Another slice of that stack is programming languages, including Python. All signs point to Python ...

I’m a big fan of using art and drawings to clarify data problems and workflows. But in this case, let’s use them to conceal the identity of common data procedures, methods and more. Below you’ll find nine images; based on the figures and words in them, can ...

I’m sure many readers got excited by the data science possibilities of the title. However, decision trees are more than statistical algorithms — in a broader sense they are any schematics used to help chart actions and consequences, whether probabilities are given or not. In this post, we’ll use ...

In 2011, Marc Andreesen claimed that software is eating the world. With hindsight, we can be more specific: Python is eating the world. The open source language is more popular than ever and sees no end in sight. While it may sound intimidating and like too much work to some analysts, ...
