ジョンズ・ホプキンズ大学(Johns Hopkins University) による The Data Scientist’s Toolbox の受講者のレビューおよびフィードバック



In this course you will get an introduction to the main tools and ideas in the data scientist's toolbox. The course gives an overview of the data, questions, and tools that data analysts and data scientists work with. There are two components to this course. The first is a conceptual introduction to the ideas behind turning data into actionable knowledge. The second is a practical introduction to the tools that will be used in the program like version control, markdown, git, GitHub, R, and RStudio....

Introductory course



As a business student from Bangladesh who is aspiring to be a data analyst in near future, I love this course very much. The quizzes and assessments were the places to check how much I exactly learnt.


It was really insightful, coming from knowing almost nothing about statistics or experimental design, it was easy to understand while not feeling shallow. Just the right amount of information density.

I was actually wondering if this is tough since I am also taking online classes from somewhere and still have work, but I think I really needed this course.



El curso es muy dinámico, equilibrando bien la exigencia con la motivación para seguir atentamente el desarrollo de los contenidos. Totalmente recomendable.

Good start in data science, I learned basic principles of R, using RStudio, integration with GitHub and also basic principles of Data Science and Big Data.

by Arman L


In this course I have studied the basic tools which will be used further in Data Science specialization. It was not difficult, but was very clear and brief

by Lim Q


Clear instructions for the practical work. The option to use the text file or video was a great way to differentiate learnings for different content types.

by Mathew K


Learned a lot of really useful stuff about version control with GitHub that I had not encountered in my PhD training , but that seems crucial for industry.

It was an informative experience, learned loads about basics of Data Science and the introduction to R was really helpful especially for beginners like me.

by Manav S


It's the best course i have come across. If someone want to become a data analyst, this is the true platform for him/her to show what he/she is capable of.

Excelente curso y excelente didáctica, aunque requiere para mi de un ezfuerzo extra, ya que el Ingles no es mi lengua principal, lo recomiendo ampliamente.



Excellent introduction to Data Science, I've learned a lot and I have installed R and R Studio. Finally, I have all books to study. Thanks you very much!!!

This is a very elementary course for those who would like to start learning about Data Science. Absolute basics from which you can build up your knowledge.

by Jonathan F


Great intro. Having no coding background, this was still a good blend of being shown the basics but still having to figure out a few tiny things on my own.

by Rathna


Very good course. I initially thought of earning a simple certificate. But I really learnt R, Rstudio and Github installations and did simple coding also.

by Vatsal M K


Thank you so much for this course....And anyone who wants to develop thier carrier in datascience must go to this course you will definetly get success...

by Abrar F


Although the computerized voice wasn't an issue. the still images could be updated to animations so that students can better understand what is being done

by Shoaib J


The instructor taught each and everything in such a simple manner that people with no background in programming would also understand the concepts easily.

by Mahmoud S A D


Excellent Course with simple and informative materials

the educational process very helpful and the approach to build the knowledge and skill is remarkable

by Mahmoud N


I think it is a good introduction to the data science specialization. It made me understand a sufficient concept about the courses of this specialization.

by Gayatri A


It is a simple and good course; starting from the tools you require, going through the installation , githhub and other basic items required to progress t

by Jason H


It's a good introductory course to get those who are unfamiliar with this topic and type of learning environment acclimated with the necessary skill sets.
