Our business has data at its core. In a competitive marketplace, we have a growing need for employees trained in the critical field of data science with strong analytical skills. The MITx MicroMasters in Statistics and Data Science provides an excellent opportunity for learners to have rigorous training in statistics, data analysis, and machine learning and to develop the skills necessary to be competitive in a world increasingly shaped by data.

Joseph Logue, Executive Vice President, Booz Allen Hamilton

MITx Micromasters Program in Statistics and Data Science is my best choice in this review list. A bit of previous knowledge in every major topic will be very helpful for you. And if you keep digging into each topic after you've taken a class, this program will be the only one you should take before diving into your projects.

Just one thing to keep in mind when you’re taking this MicroMaster's program, don’t rush and spend as much time as you can! The course might get a bit difficult for you sometimes. But be active in the community, use Google if something is not clear to you, and solve the problems on your own. At least this is how I proceed. It will take time, but you can finish it properly within 6 months. 

Why do I consider it to be the top one? If you’ve already taken some Data Science courses, just look at their syllabus. How complete it is! It has got everything from start to finish. Although you won’t find any end while learning, this program gives you everything you need to proceed. This is worth it!

Top Review

Excellent starting course on machine learning. Beats any of the so-called programming books on ML. Highly recommend this as a starting point for anyone wishing to be an ML programmer or data scientist.

Murali N

This is the best course to learn the theory and mathematics behind Machine Learning and Data Science. Although it’s a bit old course, there’s still no course made as simple and complete on theories as it is. Almost anyone you find learning Data Science or Machine Learning for a while has already taken this course. 

The only drawback of this course is that it’s taught in MatLab, instead of Python or R. That’s why I keep saying it’s the best for theories. Instead of updating this course in Python, Andrew Ng and his team are focusing on launching new and updated courses on various topics of Deep Learning. If you’re interested, take the Deep Learning AI Specialization after this course.

Top Review

Mitchell International highly values professionals with proficiency in Data Science and recognizes the need for more individuals to obtain this knowledge and skill set. It is my belief that a candidate credentialed through the edX MicroMasters program in Data Science would have a marked advantage for the following positions in Mitchell International: Business Systems Analyst, Data Analyst, Data Scientist, Data Informatics Analyst, Machine Learning Engineer.

Erez Nir , SVP and CTO, Mitchell International

I consider this MicroMasters program as an alternative to the first one in the list, the MicroMasters® Program in Statistics and Data Science by MITx. The main focus of this program is the course Big Data Analytics Using Spark. The program starts with Python programming, then proceeds to Statistics and Probability with Python. Next talks about the models in Machine Learning. Finally jumps into working with Big Data.


The program details might look minimal to you, but once you start it, you’ll see how broad it is. I recommend this to those who are mostly interested in working with Big Data. But I personally like taking the MicroMasters® Program in Statistics and Data Science by MITx, and then taking only the last course of this program which is Big Data Analytics Using Spark.

Top Review

I enjoyed the Data Scientist Nanodegree. I especially like the portfolio projects. They are sufficiently challenging, but they come with helpful instructions so that I can actually finish them and put them on my resume. The GitHub and LinkedIn review requirements also pushed me to polish my online presence. I am a lot more confident to look for a data scientist position than I was four months ago.

Ying G.

There’s one thing I highly like and one thing I highly dislike about the NanoDegree. The program costs a lot, but still, it has a big list of prerequisites. If I’m spending more than $500, I’d expect it to be a complete program. I’m okay if it takes more than a year to complete, but when the program is a complete bundle, it contains a reliable flow.

On the other hand, I like how it truly prepares for the industry. To become a Data Scientist takes a lot of effort. So instead of stacking lots of courses at once, they focused only on preparing you for a job with some challenging projects. Still, if it was a zero to hero program, I’d rank it as number 1 or 2 on the list.

This professional certificate program serves a wide range of knowledge. The projects give a real-life problem-solving feel. I just missed one thing in this certification, there’s no course on the mathematics required for Data Science. Maybe that’s because Coursera has an outstanding specialization, Mathematics for Machine Learning by Imperial College London. 

You might find the first part of the course not that engaging. But if you stick to it, you definitely will get some unique knowledge and experience. The same program is on EdX, Professional Certificate in IBM Data Science. But the one on Coursera is relatively cheaper.

Very informative, fun to get through, learned a lot about the basics of what I'll be diving into more. There's a lot more to learn but this was a good foundation.

Kyler Gould

I recommend this course to those who are just starting with Data Science or Machine Learning, and not sure about whether it is really a good field for them. You’ll only have the foundational knowledge of most sectors you need to master to truly become a Data Scientist. I really missed the data visualization part.

Unfortunately, this is the best Data Science course on Udemy, and lots of reviewers say it will make you a Data Scientist, which is a lie. Just build your foundation with it, and then grab one of the top programs stated above. This will help you understand those courses very easily. So it’s worth trying for absolute beginners.
