Learner Reviews & Feedback for Exploratory Data Analysis by Johns Hopkins University
About the Course
Top reviews
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.

•PCA and SVD are not included in any assignment, it will be great if they are in the future
By Huang-Hsiang C
•Plotting is very usefulIt would be great to have a step by step breakdown of PCA and SVD.
By Mark F
•SVD could be explained a little better i think. I am still not exactly sure how it works.
By Irmgard T
•great course...though I would have preferred less focus on cluster and k means analysis.
By Manuel M M
•It is a good course but in my opinion it is basically support with the R swirl() guide
By Ross D
•Was a little perplexed that we did not address clustering at all in the assignments.
By Prathamesh
•SVD & PCA videos need improvement in terms of background knowledge and understanding
By Migdonio G
•You should give more datasets for independent practice! Something we can play with.
By Sawyer W
•Good course. Mostly focuses on how to visualize statistics from the data quickly.
By Shuwen Y
•great course but wish to have more materials or explanation on svd and PCA part.
By KAMAL D
•Only the 3rd week was confusing but the confusion was revoked by swirl package
By Philip E W J
•Would have needed a litle more in depth explanation of the clustering analysis
By Subramanya N
•ggplot should have been given more emphasis. It warrants a course on its own!
By Greg R
•Pretty good course. Nice content. Middle section on clustering felt random.
By Pavel B
