Data Science: Visualization

Harvard University via edX

Overview

Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only!

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.

  • I loved the first course in the series (R Basics) and this one is the second in 9-courses Data Science program from Harvard. Once again the course is engaging, the videos are interesting and ggplot2 library selected for data visualization is probably the best R tool available.

    However I didn't like how assignments are made. Excercises are based on quite complicated pieces of code, not always clear and not always clarified properly during the course. There is a lot of doubts and Discussion Forums are full of people who written code meeting all conditions and still not accepted by algorithm. I hope the next course in the series will be a bit better balanced.
  • Excellent course! Comprehensive curriculum, engaging instructors, and practical applications and theory.

    This is the 2nd Course of the Data Science Specialization from HarvardX.
    It is mainly about using R ggplot package and tidyverse to learn about all the powerful graphical capacities of R language.
    Not theoretical, nor about programmation, this Course is quite interesting and practically oriented: you get a lot of practical knowledge in a minimum amount of time and effort.
    The satisfaction with this Course leads me to take the other ones in the Specialization
