The course material was in a structured manner and very easy to understand. One feedback I would like give is that there should be a form of one to one communication with instructors, so that students can clarify their technical doubts since this is a course based on coding.

Great course to get started with data science using R as primary language. Good data practices are encouraged and use of GitHub for version control gives additional confidence to anyone wishing to preserve their work that leads them up to the solution to the problem at hand.

It's an excellent introductory course for the specialization, I have recommended this course to a friend because I have found the content pretty useful. I will continue with the other courses of the specialization and I'm very grateful to have this opportunity from Coursera.

This is a nice course and well taught by all facilities made available by the facilitators. As soon as am financially able to start to finish from where I stopped, I will activate my remaining course left to roundup Data Science Specialization.

I really appreciate. Thank you.

Basic course introducing the minimum tools to start your journey in data science. The course was very important for me to get up to speed with Git and GitHub. All the information was given in a concise and objective way, yet covered all basic important points of such tools.

Might look trivial at first glance to more experienced users, but was very much essential for a complete beginner like me. Gives a nice overview of a somewhat overwhelming (and sometimes intimidating) field and equips you with the basic tools necessary (like how to use git).

Super insightful course, I was happy to get to learn to use version control systems. I would recommend it for everyone who is willing to get into data science. This course opens new set of possibilities and provides you the foundation needed to further advance your skills.

Excelente curso, aumentó de manera óptima mis conocimientos y resolvió todas mis dudas, ahora tengo gran parte de las herramientas para llega a ser una buena cientifica de datos y aparte de que aprendí mucho sobre el tema, pude practicar el inglés y aumentar mi vocabulario.

The "Data Scientist's Toolbox" offered by Johns Hopkins University is a good head start for the newbies in the field of Data Science. The course gives the brief introduction to various software used by a Data Scientist that is R, R studio, Git hub and Git (version control).

I really enjoyed the course, the quizzes are very helpful because they taught me to listen and watch the videos carefully so that I can remember the content. As an IT student this course will be very helpful to me, and will open more opportunities for me in the ICT sector.

Very good introduction to data science. It gives a general overview on data and its problematics but also tips and help on how to start with the basic tools that will be needed (I haven't done any R programming and didn't have a github account so that was helpful for me).

It is a very good course to get introduced to the world of data science. Working knowledge of R, RStudio and GitHub is covered in a very nice and organised manner. I feel more confident and equipped to proceed further and learn how to solve problems through data science.

Интересно было посмотреть как работает один из лучших исследовательских университетов мира.

Кроме настройки программного обеспечения много узнал об основных принципах науки о данных.

Очень понравился пример с Хилари Клинтон. Возможно это был роковой момент в её поражении.

This is not a coding course. It is a course to bring you up to date with the logistics of using R: downloading packages, using RStudio, using GitHub version control, and familiarizing oneself with the overarching concepts of experimental design, statistics and big data.

A very easy to understand, nice and simple course. ample quizzes and puzzles available. A recommendation : please include a thing or two about RStudio Cloud. Especially, please include how to tie up your github repo to RStudio Cloud; as the procedure s different for it.

It's really enjoyable, a lot to know and a lot to discuss. The other links provided for more details are very much helpful. The feature of the discussion form is very helpful. Thanks, to Coursera and the team of Coursera for your high great work to open this platform.

Muy buen curso introductorio en el que se pueden observar las herramientas necesarias para realizar análisis de datos, además de que muestran quienes son Científicos de Datos en la actualidad y qué tipo de análisis realizan, todo adquiriendo la información de internet.

Setting up the environment is often the tricky part that deters people from moving into, or back into coding. This class provided me with a hand-holding needed to start coding again. I recommend this course as a kick starter for those who were on legacy environments.

The course content is great, with great real world examples linked to the topics.

The quiz questions are of varying difficulty, most are easy if you give the right time to the course, but some can trip you up if you don't put the necessary thought and time into them.

What a great introduction. It needs a lot of reading and self developing to be able to do that project at the end. It's kind of difficult but you'll feel that you've really learned something that will be useful for the rest of your life. Thanks JH and Coursera staff.

Es un buen curso. te lleva de la mano pero no te da todo digerido en cierto momento debes buscar alguna solución para las tareas que te piden pues por razones de versiones ya no funciona igual.

Sin embargo el contenido temático es lo importante y me pareció perfecto.

A good introduction to analytical processes and tools. The course by itself, however, is only a first step. I find many threads begun but not tied together. I anticipate that the remaining nine courses will expand and consolidate everything opened in this course.

Es un excelente curso, te insta a ser ordenado en tu trabajo con el uso de las herramientas que existente para que podamos a cada proyecto que tengas y podamos refrescar rápidamente todo el historial con el control de cambios. ¡Excelente introducción del Programa!

The course is great at explaining the preliminary steps for setting up an R development environment and describing the basics of data science. Videos were paced well, not being too short or long, which allows the viewer to stay focused and interested. Recommended.

Quite helpful course in teaching the fundamentals of data science, do not expect to use statistical analyses programs effectively with the help of this course. This course's main aim is on teaching the fundamentals of data science just like we see in a university
