This course covers the essential exploratory techniques for summarizing data. These techniques are typically applied before formal modeling commences and can help inform the development of more complex statistical models. Exploratory techniques are also important for eliminating or sharpening potential hypotheses about the world that can be addressed by the data. We will cover in detail the plotting systems in R as well as some of the basic principles of constructing data graphics. We will also cover some of the common multivariate statistical techniques used to visualize high-dimensional data....



Very good course! It provide me the foundation in learning how to plot and interpret data. This will definitely strengthen my "R programming" to generate publication type figure for my genomics data!


This is the second course I have taken from Roger Peng and both were outstanding. I have a strong math background, but not much of a background in stats, but this course was very approachable for me.

This was a great course. I learned how to use several graphic systems within R, and to imagine how to make clear answers to questions using plots.

Very good class. Of the four I've taken so far, this one has given me the most confidence that I could be successful as a data scientist/analyst.

創建者 Alexis C


This was an important class because in future classes in the certification peer reviewed projects require some sort of exploratory data analysis.

創建者 David S


Great Course. Lectures did diverge from Quizes and projects but still was good practice of looking at a set of data and reporting out from it.

創建者 Fenneken K


Learned a great deal. Especially on clustering.

The second project could be a little more challenging; I overestimated the answers requested.

創建者 Ishwar N


Highly recommended course for budding data scientist. I loved the John Hopkins univ pedagogy and peer review system. The content is great.

創建者 Charles K

創建者 Donald M


Excellent course, it has allowed me to learn the bases to explore and analyze data.

Dear teachers thank you for sharing your knowledge

創建者 Roman O B


Great overview on explonatory data analysis and preparing graphs in R. I could apply the now knowledge directly to my current work.

創建者 Diqing F


The course is interesting and values practicality. The exercises and the projects really helped me a lot in grasping the knowledge!

創建者 Nikodem L


This has been a great course. Accompanies by a book, it constitutes a great piece of material about exploring and visualizing data.

創建者 Bhargava B


This course really helps you to learn the fundamental exploration techniques. The assignments and the examples are really helpful.

創建者 Marat K


Very good introduction to Exploratory data analysis for beginners, the material is structural, lectures are interesting and useful

創建者 Amith c


A Must have course for beginners in Data Exploration and Analysis. The best part is that exposure to these amazing concepts in R.

創建者 ZAMI K


If you really want to learn, Coursera is the best option. There is a myriad of options and sources this specialization provide.

創建者 Ted M


The lectures in this course included theory and examples on PCA and SVD - however this was missing from the practical materials

創建者 Juan H

創建者 Oscar A


If you want to know how to use plotting systems like ggplot2 and how to explore your raw data, this course is really Useful!!

創建者 Marta R


Really good course, with amazing videos and examples. I have learned a lot and I think the projects were really interesting.

創建者 Kevin C


This was an excellent course full of useful exercises, assignments and lectures. I took these classes for the data analysis

創建者 Andaru


basic plotting and getting the feel of data, this course really helped tackling that and seeing perspective in data analysis

創建者 David R


An extremely interesting course, with many practical applications many of which I've applied in my day to day work already.

創建者 Gaurav B


Loved it , the K means was pretty difficult for me but others was a breeze as i had experince in ggplots before the course

創建者 Mehrdad T


EDA is essential part of data analysis and in this course the concept is well covered especially through the assignements.

創建者 Alexander D


i very much like the course book. The course book helped me most in really learning the material and how to build plots.
