Dataquest

Very good code environment! You don’t have to download python in order to code, you can only go to their site and start coding. Easy to learn with many exercises to practice. After you finish the theory you start to apply your new skills in real project... Read More and this makes your knowledge solid.

DataQuest Courses and Modules for learning Data Science are very well put together. There is a sequential step by step process that is hands on giving practice which is important. As supplemental to a Data Science course or program DataQuest is very helpful.... Read More I personally used DataQuest to help with my course work as a learning tool. For the price one cannot beat this Data Science LMS and it pays dividends for anyone willing to learn Data Science.

I am currently about two-thirds of the way through the R for Data Analysis course with Dataquest and felt compelled to write this review.
For over ten years my analyst career has been solidly planted on the strategy side of corporate. I have become proficient... Read More with "point-and-click" data analysis programs such as Excel, SPSS Statistics, Tableau, SAS EG, among others. There simply wasn't much need for me to learn more powerful tools. Unfortunately, a major reorg has resulted in me being unemployed for the first time in 14 years.
After looking at the current job market, I decided the best way to increase my desirability to potential employers was by deepening my knowledge of more powerful tools such as R, Python, etc.
Dataquest stood out from the lesser alternatives because the courses are well organized, written clearly, have good pacing, and provide relevant examples. I like the blank page aspect of writing pieces of code with each lesson as opposed to the "fill-in-the-blank" style of other online learning resources. Also, the response time to emails and inquiries via the Slack community have been exceedingly fast.
I look forward to taking more courses with Dataquest and would recommend it heartily.

Right now I'm going through the online Data Scientist Python course, with Dataquest.
So far I've completed two modules - 1. Python for Data Science: Fundamentals, 2. Python for Data Science: Intermediate,
and now I study the 3rd module - Data Analysis and... Read More Visualization, using NumPy and pandas.
I find this course beneficial and satisfactory, for the following reasons:
a. The curriculum is well designed, from fundamentals to enhanced stages.
b. There are many hands-on real exercises, with online verification of the results + hints and tips.
c. There are abundant explanations, with reference to specific Python documentation.
d. In addition, Dataquest team is supportive and helpful.
e. Lastly, the value - I find it cost-effective, with very reasonable price.
Note: the Attended date specified is the beginning day of the course. It is not a one-day class!!

I have been using dataquest for about a month now, came in with no experience in programming, and now I am at level in python where I can import and clean simple datasets and make simple analyese all by myself, without going back to the material. Their... Read More lessons, or missions as they are called, were designed to build on the concepts that you learn untill you gain a solid grasp on them. The use of illustrations in some lessons was helpful, but I wish more lessons had more illustrations. The pdf summaries at the end of each mission is very helpful, and could be improved if all summaries were consolidated into one large cheat sheet for each module.

I have tried a few times to start an online course but there was always something missing, no exercises, challenges or projects. Finally, through Youtube, I discovered Dataquest and since then learning data science has been fun, I take classes, apply... Read More what I have learned and can do projects to create my portfolio.

The format of most online Data Science bootcamps is very similar: sequential lessons that build on each other to give the student an understanding and competency in a given domain. Dataquest is no different but stands apart for me for two reasons: the... Read More way the material is presented and the quality of the material itself.

Most major online data science bootcamps (DataCamp, edx, Coursera, Udacity, etc.) use video lessons. You watch a 10 minute video of someone talking with diagrams and examples appearing over their shoulder at appropriate times and then are tasked to apply the lesson in a coding exercise. Dataquest is unique (in my experience) in that there is no video - learning material is presented as text. In my opinion there are two major advantages to this:

1. You can read much faster than someone can talk. This opens up the possibility of a much thorough, expository explanation of a concept/competency being digested by the student in a similar amount of time. In my experience Dataquest takes full advantage of this - they often "get into the weeds" and explain why the code you are being prompted to write works the way it does whereas a lot of video courses necessarily take a more high-level, prescriptive approach.
2. It is much easier to reference text than a video. If you need a refresher as you do the practice code or are confused by a concept, it is much easier to find and re-read the relevant material in a well organized page of text compared to scrolling through a video.

In no small part due to the advantages of the written word the material on Dataquest has also been top notch (I'm roughly a quarter of a way through the course). The lessons are well written and they go beyond just telling you how to do something - they explain how and why the code you are writing works/is optimal (e.g. how vectorization works in Pandas and why it is better than using an element-wise function to complete a task). The read/do dynamic of each lesson is also helpful as you are immediately prompted to think about and execute the concepts you've learned, practicing the repetition that will ultimately breed familiarity in the process.

If you learn best by reading than Dataquest is a great option. Even if you think you are a visual learner it is worth checking Dataquest out and experiencing the depth and accessibility that written material provides.

Data Science is the future, if you really want to specialize in this Field, I recommend you to try Dataquest it is simple, easy to understand, and well organized, step by step program, and the most important thing not boring :) you don't have to have... Read More any prior experience, there is a free trial, then if you like it(as most people do) you can purchase it at a very convenient price and you will not regret!
I wish everyone who read my review good luck!

Data science is a coplecated aria. The threshold of entry into it is very high. having tried training on different platforms such as udemy.com, coursera.com, etc. I was practically at a dead end. I was almost sure that this was not for me and that I could... Read More not overcome it. Well, when I found the Dataquest I realized that everything is real . Material submitted for users with zero knowledge. Everything is accompanied by very interesting examples. Even math lessons are accompanied by examples in Python that you rarely find on other platforms.

The perfect combination of theory and practice. Very user-friendly interface and motivating email newsletters. Quality is top-notch. I tell you this as a practitioner of Quality assurance engineer.
I will no doubt recommend you Dataquest as well as I recommend it to my friends in personal communication.
