Learning data science used to be difficult

So you’re a business professional that wants to accelerate your career by learning data science.

This is an excellent decision! Until you try to figure out where to .

The prospect of learning data science seems daunting. There are an endless series of decisions that need to be made.

“Which language is right for me?”

“What libraries should I use?”

“How much time will this take me?”

“What results will I get?”

“WHERE DO I ?!?!”

We’ve been there, which is why we’ve created Business Analysis With R for you.
Taking the guess-work out of learning data science

Business Analysis With R is a revolutionary program that takes the guess-work out of learning data science.

We provide you:

A complete learning path with R: R is the perfect data science language to learn if transitioning from Microsoft Excel. R is functional, which is very similar to Excel.
A cohesive tool chain: You use a common programming API called the tidyverse that simplifies the process of importing, joining, cleaning, wrangling, visualizing, modeling, and communicating data & results.
Comprehensive resources: You are provided cheat sheets, code templates, and resources that speed up learning and make referring back to materials simple.
A 7-week system that packs in a year of knowledge: It normally takes a year or more to learn the tool chain. You learn everything in 7 weeks w/ 5-10 hours per week of coursework.
Full life-time access: Once you purchase the course, you gain life-time access to content now and any updates in the future.

 

We accelerate your learning through a methodical approach combining tools, resources, & projects.
Tools you will learn

You will learn an amazing tool chain called the tidyverse that makes performing data analysis fast and efficient. You’ll learn how to use each one of the R packages, enabling you to perform the entire data analysis workflow including:

Data import
Joining Data
Data Cleaning
Data Manipulation
Visualization
Modeling
Reporting

Resources you will get

The Business Analysis with R course comes packed with resources, tools, frameworks, and templates. Too many to go over. To talk numbers, you get:

100+ Code Lectures
15+ Hours of recorded content
10+ Cheatsheets & Walkthroughs
20+ Downloadable code templates
2 Projects
and more!

Projects you will complete

The Business Analysis With R Course incorporates two projects as a guide for our learning:

R&D Project – Goal: Utilize data to assist the Research & Development department in coming up with a new product idea and a targeted price point
Marketing Project – Goal: Use data mining techniques to segment the customer base empowering the Marketing department to implement targeted emails to customers in turn increasing engagement

In week 7, you will create two reproducible business reports containing the results of the analysis.
Challenges you will conquer

The Business Analysis with R Course includes a number of challenges where you will apply what you’ve learned. Shown is the Week 6 Challenge that extends the Customer Segmentation to a real-world challenges where you will segment Companies by their stock price movements.
Summary of what you get

A methodical training plan that encapsulates 1+ years of knowledge into an accelerated 7 week training – compared to on premise workshop ($5000 value)
Hundreds of resources ($1000 value):
10+ Cheatsheets with Walkthroughs
20+ Downloadable Code Templates
