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.

Very exciting, Did you Know that just by exploring your data can help you reduce the list of models you want to try out

創建者 Erdem Y


There should be more content devoted to SVD . more theory and quiz questions and workouts to emphasize the methodology.

創建者 James E H J


Great course to learn how to play with data - a good intro to things like Kmeans and hierarchical clustering, as well.

創建者 Avinash A


Nice content. Make sure to take the SWIRL course offered. That really helps to get a hold on the course. Recommended!

創建者 Huynh L D


This course is really awesome!

Highly recommend. You'll learn all the data visualization techniques in this course.

I really learned a lot in this class. I plan on going over the materials as well as taking one of the next courses

創建者 William G C


This is a great course! I really enjoy the pace. Plus, the real world application isn't a bad thing at all either!

創建者 Yergali B


I strongly suggest for future Data scientist, if you know R language with making Plots, you can be a good analytic

創建者 Emmet C


Excellent introduction to various graphics packages in R. I've already been able to apply these skills in my job.

創建者 José G Z r


Very interesting course. the week 3 is the most challenging and the practical case of week 4 is quite cool also !

創建者 Mauricio C


Great tools and insight to start exploring Data. Also great stuff to practice previous training on Data Science.

創建者 Jorge B


Great Course, that require to use all the topics you have learned in the previous courses of the specialization.

創建者 Dhananjay M


This course if very helpful. Lectures and assignments provide a great opportunity to gain hands on experience.

Very excellent course structure. Gives you all the bases you need to get you started in exploring your data.

創建者 Ishwarya M


I liked both the course content as well as the assignments. Great course to learn exploratory analysis in R.

創建者 Nathan H


All of the quizes and assignments we're able to be completed with the material provided in the course videos.

創建者 Andrew M T


Brilliant dive into the basics of exploratory data plotting. A very useful course for data science beginners.

創建者 Youcef M


G​reat course that unpackes difficulties in learning data analysis with R. The Swirl system is just "Great".

創建者 ooi s m


great course for fundamental exploratory data analysis, good starting point for using R to do basic analysis

創建者 Dimitrios G


Great course, really gives an insight on how you can get a set of data and actually make some sense from it.

創建者 Ramesh G


Great introduction to exploratory data analysis. Would've been great if more advanced material was covered.

創建者 Nicholas P


Would have preferred a more technical explanation of the dimension reduction techniques, but great overall

創建者 Anne M


Excellent class with easy-to-understand videos. The quizzes and homework really help me master the topics.
