Hey there. My name is Zach Bobbitt.

I have a Master of Science degree in Applied Statistics and I’ve worked on machine learning algorithms for professional businesses in both healthcare and retail.

I’m passionate about statistics, machine learning, and data visualization and I created Statology to be a resource for both students and teachers alike. 

My goal with this site is to help you learn statistics through using simple terms, plenty of real-world examples, and helpful illustrations.

You can find me on LinkedIn here.

Why Learn Statistics?

In an increasingly data-driven world, it’s more important than ever to know how to read and work with data.

It also pays to understand data! Some of the fastest growing professions in the world are centered around working with data, including:

  • Statisticians
  • Data Scientists
  • Data Engineers
  • Data Visualization Experts
  • Database Administrators

Best of all, these types of jobs are associated with high salaries and low stress, according to the U.S. News & World Report.


If you’re just getting started with statistics, I recommend checking out this page that lists all of the basic stats tutorials on Statology.
