“I’ve done courses from DataCamp and Dataquest. In my opinion, Dataquest is much better because it makes you make an effort.”

Jorge Varade

Data Analytics Engineer

Course overview

In this course, you’ll learn how to respond to key business needs using data, such as understanding churned customers, pricing, customer ratings, etc. You’ll learn to work with ambiguous, imprecise, and subjective data — the “fuzzy” side of data — to present key business metrics like churn rate and net promoter score.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. You’ll also apply your skills to a guided project involving a realistic business scenario to build your portfolio and prepare for your next interview.

Business Analyst at Aditi Consulting

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”


Jessica Ko

Machine Learning Engineer at Twitter

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”


Victoria E. Guzik

Associate Data Scientist at Callisto Media

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
