Be a Part of the Data-Driven Future


Is the future of your profession being reshaped by machine learning? Do you want to be a part of this data-driven future? Do you think your lack of math/programming skills will hold you back?

It’s hard to avoid all the social media posts, magazine articles, or news clips trumpeting how machine learning (often referred to as “AI”) is permanently changing the way organizations operate – and changing the expectations of employers.


While data has always been used in business, things have changed. Functions like Human Resources, Product Management, and Customer Service are embracing advanced analytics to drive better business outcomes.


The simple fact is that machine learning is a valuable skill for ANY professional to have more impact at work with data. Imagine employees that can use data to answer questions like these:


[HR] - What factors are highly predictive of high performers?
[Product Management] - What feature usage(s) are highly predictive of a sticky customer?
[Customer Service] - What are the factors customer services can influence associated with churn?

Do you think these employees will be more effective, and prized, in the data-driven future?

My self-paced “From Excel to Machine Learning” online course bundle will use your basic Excel skills and springboard you into using machine learning to analyze your business data.



The 20% of R and Machine Learning Delivering 80% of ROI.


I've designed this course bundle to give you the most valuable R programming and machine learning skills, fast. Like Microsoft Excel, R is a large and powerful ecosystem for working with data. Just like Excel, you don't need all the R bells and whistles to effectively work with data.

By focusing on the 20% of machine learning that drives 80% of ROI, you quickly gain valuable skills to craft new business insights and have more impact at work. Here's what's included in the course bundle:


20+ hours of video lectures. Using your Excel skills, you will quickly learn the basics of working with data in R. Then you will learn how to efficiently work with multiple tables of data (e.g., joining tables). Lastly, you will learn how to explore/analyze data using powerful data visualizations.


With your new R programming skills you are ready to enter the world of machine learning. You will build ML skills using decision trees and the mighty random forest algorithm. These techniques are battle-tested and are perfect for analyzing business data. They also have the added benefit of being quite easy to learn.

17 hands-on experiences. You learn R programming and machine learning by writing code. The course includes 8 hands-on exercises and 9 hands-on labs for you to cement your R and machine learning skills.


A robust introduction to machine learning. You will acquire the fundamental skills required to successfully apply machine learning to your business data. This includes exploratory data analysis, feature engineering, the bias-variance tradeoff, and model tuning.


Lifetime access to the course and to me. Your course purchase includes lifetime access to the content, any future updates, and access to me for your questions via the course platform.


30-day, no questions asked refunds. If you are not completely happy with your course within 30 days of purchase, ask me for a refund.

Real Students. Real Results.

"First, I'd like to thank Dave for the great effort he put on this course (Introduction to Machine Learning With R). For an introductory course, I found it very detailed and well explained. The methods he uses on teaching are just awesome and that makes the course way too easy to understand.

Dave is also very responsive and that just adds to the awesomeness. I honestly can't wait to take more courses with him. Also, the things you learn in this course are highly applicable in real life, and he makes the math to be so easy. If you are a beginner in this field, then this is the right place. If you are an experienced data scientist trying to do a refresher course, this is the right place too.

Keep up the good work Dave, I'm inspired. Thank you."

- Joseph Kamau

"I completed David Langer's course, R Programming Made Easy. As a decision support analyst, I have a burning desire to solve more problems and not let the data scientists have all the fun. My first step on that path is familiarizing myself with one of the primary languages used in data science, R.



Dave's enthusiasm for data digging and problem-solving shine through in the videos.When I ran one section of code and looked at the results, I shouted, 'Whoa!' because of the implications.

So if you want to quickly get up to speed on the basics of R, I recommend Dave's 'R Programming Made Easy'. I will definitely be signing up for his future offerings."
