About this course

In this Data Cleaning Project Walkthrough, you’ll learn the two “phases” of data cleaning and data visualization. You’ll also learn the valuable skill of combining multiple datasets and preparing them for analysis.

Once you’ve done that, the real fun begins ⁠— you’ll complete two data analysis and visualization portfolio projects using data from some of the biggest names in film culture. It’s time to synthesize everything you’ve learned about data cleaning and put it all into practice!

This course focuses on the following:

  • Introducing the “two-phase” process for completing end-to-end data cleaning projects
  • Building skills in combining, manipulating, exploring, and analyzing multiple datasets
  • Completing strong and compelling data cleaning portfolio projects from start to finish

How Our Data Cleaning Project Walkthrough Course Works

By now, you know how much time data professionals spend turning incomprehensible and messy datasets into clean, uniform, and useful datasets. In your data science career, you’ll rarely get a dataset that is precisely the way you need it to be. That’s why data cleaning is such an invaluable skill in data science. We’ve created this course to help you acquire, refine, and retain this skill to make you a valuable asset to any data science team. We’ve structured this course to build on our previous Advanced Data Cleaning course.

At Dataquest, our focus is to help you get hired as quickly as possible. That’s why we only use the best of the best teaching methods to help you develop the career skills you need.

We designed this Data Cleaning Project Walkthrough course with your career success in mind. We’ve carefully crafted every one of our hands-on and interactive lessons to go beyond simply learning data cleaning — you’ll put it into practice using real-world datasets.
