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 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.
par Alexis C•
This was an important class because in future classes in the certification peer reviewed projects require some sort of exploratory data analysis.
par 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.
par Fenneken K•
Learned a great deal. Especially on clustering.
The second project could be a little more challenging; I overestimated the answers requested.

If you really want to learn, Coursera is the best option. There is a myriad of options and sources this specialization provide.
par Ted M•
The lectures in this course included theory and examples on PCA and SVD - however this was missing from the practical materials

This was an excellent course full of useful exercises, assignments and lectures. I took these classes for the data analysis
basic plotting and getting the feel of data, this course really helped tackling that and seeing perspective in data analysis
par David R•
An extremely interesting course, with many practical applications many of which I've applied in my day to day work already.
par 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
