In this online course taught by Harvard Professor Rafael Irizarry, learn basic data visualization principles and how to apply them using ggplot2.

As part of our Professional Certificate Program in Data Science, this course covers the basics of data visualization and exploratory data analysis. We will use three motivating examples and ggplot2, a data visualization package for the statistical programming language R. We will start with simple datasets and then graduate to case studies about world health, economics, and infectious disease trends in the United States.

We'll also be looking at how mistakes, biases, systematic errors, and other unexpected problems often lead to data that should be handled with care. The fact that it can be difficult or impossible to notice a mistake within a dataset makes data visualization particularly important.

The growing availability of informative datasets and software tools has led to increased reliance on data visualizations across many areas. Data visualization provides a powerful way to communicate data-driven findings, motivate analyses, and detect flaws. This course will give you the skills you need to leverage data to reveal valuable insights and advance your career.

FAQs

Are there any prerequisites for these courses?

No prerequisites are required. However, courses later in the series will assume you have the knowledge and skills acquired from earlier courses.

We suggest learners take the courses in the order in which they appear on the HarvardX Data Science Professional Certificate page.

If I don’t finish all the courses during this run, can I pick up my progress in the next run of courses?

Yes, to maximize flexibility learners can complete the courses across different runs of the course.

However each individual course must be completed within the same course run as progress on an individual course will not transfer between course runs.

I'm not a data scientist. Can I still take this course?

Yes! You don’t need to be a data scientist to take these courses. The HarvardX Data Science Professional Certificate is designed for those who want to learn the fundamentals of data science and programming with R.

What is the difference between the HarvardX Data Science Professional Certificate and CS50 Computer Science courses?

Courses in the HarvardX Data Science Professional certificate teaches learners the fundamental knowledge of data science, including essential data science skills such as data wrangling, programming with R, data visualization and other skills.

The HarvardX CS50 courses teaches learners the fundamentals of computer science including some commonly used programming languages such as C, Python, SQL, JavaScript plus CSS, and HTML.Learners in CS50 can explore computer science, mobile app and game development, business technologies, and the art of programming in other CS50 courses.
