Course overview

In this course, you’ll learn the most common basic data structures you’ll encounter in the data analysis workflow. You’ll learn how to work with vectors, matrices, lists, and DataFrames. You’ll be able to index vectors and matrices to extract specific elements and apply functions to vectors and matrices to perform calculations. You’ll also learn how to create and index lists to extract objects. Finally, you’ll learn how to define a tibble, filter and subset the data in a tibble and employ piping with tibbles.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. The course will wrap up with a guided project that will enable you to perform a data analysis by investigating COVID-19 Virus Trends

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!”
