I am a huge fan of trying to take the complex, detailed, and unmanageable into a concise, usable and understandable list or outline. I love seeing subjects like data architecture management, data modeling, programming languages, and even Data Science put into visual models that make it easier for others to see conceptually how it exists.

You up for learning something new? or maybe like me want to “do” statistics? If you are looking to do data analysis then R is a great tool/language to learn.
What is R?
R is a system for statistical computation and graphics. It consists of a language plus a run-time environment with graphics, a [...]
I heard an interesting comment today from a Data Scientist that really got me thinking. She said “We do Insight-to-Action Analytics and not Nice-to-Know analytics“. I admit its pretty catchy but I had to stop for a second and think about what that really means.

If you haven’t gotten a computer science degree you might not have spent much time on the topic of binary trees. Binary Trees are a key concept in the study of algorithms and data structures and are used to implement a binary search tree (BST) and binary heaps, as well as finding applications in efficient searching and sorting algorithms.
If you are looking to program in python it is essential you understand how to use packages to more than anything make your life easier. Packages are blocks of code that are written and made available for you to use in your code. Now one of the best and most widely used packages (really its [...]
Sometimes its amazing how very simple concepts can actual be made so complicated and for little reason. For those of us who don’t have a Stats background but want or need to understand statistical concepts it doesn’t help that they are taught in a way that doesn’t make it easy to understand. Here I will [...]
Ok, let’s assume its the January 1st again and you have your new year’s resolution list in front of you. Since we are assuming, let’s also assume that one of the items on your list is to learn how to program in python! That’s funny, since you want to learn python I happen to have [...]
In most data projects or tasks there is at a very simplified level really 3 main steps:
Import/Connect to the Data Work with/Analyze the Data Present/Extract the Data and/or Information
One of the key skills that will prove critical is to be able to connect to all sorts of data sources. Here I will show [...]
Here is a fantastic article by Bernard Wehbe, Founder and Managing Partner, StatSlice Systems. Here are the eight principles that Wehbe points out:
Let your passion bloom Never stop learning Improve your presentation skills and become an ambassador for analytics Be the “go-to guy” for tough analytics questions Ask questions until everything [...]
