존스홉킨스대학교의 Getting and Cleaning Data 학습자 리뷰 및 피드백

Great course. I really enjoyed it!

The course material is helpful enough to deploy skills in my research

This course is a nice introduction to the complex process of getting and cleaning data in R. It introduces you to some fundamental tools in the area, such as the dplyr and tidyr packages, and touches upon the most important aspects of data gathering and transforming. The final project is an interesting mix of technical challenges with a touch of intelligent practices in data handling and sharing. Whatever your level in R programming and data science, this course is an enjoyable hands-on experience.

Nice course.

Excellent course on using R for getting and cleaning data.

More challenging than the "R Programming" course. The instructions for the final project were a little vague, but I think maybe this was intentional to promote discussion. Definitely give yourself plenty of time to complete the final project if you take this course. The principles of a tidy data set might seem like common sense, but in practice it's more challenging than you might think. I highly recommend taking this course even if you think you know what a tidy data set is.

this course is a hands of this specialization in R.

this hands use to play with a raw and tidy data in R.

A very Important course for working with R and data science in general.

Just Amazing, one should take this course for betterment

Great Course for you to learn in more detail how data processing works in Data Science.

Muy interesante, bastante información y todo muy bien explicado

Really constructive and nice course

Great course and easy to understand for a beginner.

This course is one important step towards becoming a Data Scientist.

Very good course. Dr. Peng did a nice job of presenting the material. The projects and quizzes were challenging as well as educational.

A very practical and useful course!

Excellent course

Great course with detailed exercise about what's most important task in Data Science, "Cleaning Data"

It is great time. The course content was amazing. I learnt lot of new things.

I liked the course project!

Fantastic course!

Better than R Programming. Still very hard, but worthwhile.

The class was very interesting and useful, although I would have liked more opportunities to do web scraping in the problem sets.

Love quizzes and a course project. Working on them develops you as a data scientist

Useful general course on tidying data and learning to import into R from various sources. Doesn't get into sequencing data import, but looks at other common ones
