Course overview

This course is part of the “Introduction to Data Analysis with Excel” skill path, which we designed for those seeking the practical skills in Excel to perform data analysis and visualization — and ultimately help organizations make better-informed decisions. We designed it for aspiring data professionals with little experience and learners who use basic Excel in their daily jobs and want to enhance their skills.

In this course, you’ll learn how to develop business insights using PivotTables, how to identify trends using time-series analysis, and how to create data visualizations to tell meaningful stories. You’ll also learn how to summarize and visualize relationships between categorical and quantitative variables.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.

Key skills

  • Using PivotTables to analyze data and discover business insights
  • Working with time-series data to identify trends over time
  • Confirming a relationship between an independent and dependent variable using linear regression
  • Estimating the sensitivity of an output to given inputs

“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.”

“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!”
