There some inconsistencies in code used in videos. There are some problems with Python 2 and Python 3 compatibility too. Quiz await exact numeric values in some answers, this is not correct taking into account the statistical inaccuracy.

Best course for People who have basic understanding about Python programming, Machine learning and statistics. The assignments are flexible and easy to complete. The course includes both theoratical and technical aspects of data science

Thank you Romeo. I really enjoyed your videos and your enthusiasm - I have been inspired. The activities were very well structured although there was some confusion initially when tasks needed SQL but the videos showed RDD solutions.

Great course ! As I've already had some fundamental knowledge about how to operate data analysis with Spark, the task is kinda easy for me. But this is just the first intro of the whole certificate. Keep fighting! Thank you Romeo :)

awesome course, got a good understanding of statistics in an intuitive manner.

The main strength of this course is that, this course will help you to develop intuition of the whole data science concepts into the real world scenario.

Covers exactly what is required for data science using spark in case IoT data applications and the fundamentals required for the advanced data science topics . I am happy with the course and the topics that I have learned so far!

Challenging, with a strong introduction to Data Science concepts an practical application. Valuable insights for how to get meaning from data. Enthusiastic instructor who clearly enjoys teaching and sharing about this subject.

I learned a good amount about Apache Spark, IBM Watson, and integrating both with Python.

I liked the shorter videos with multiple checkpoints throughout and found the assignments and tutorials to be sufficiently challenging.

As someone who has taken dozens of online courses across many platforms, I very much enjoyed this course and I am looking forward to continuing the specialization! Well structured and assignments that actually made sense.

pretty good course for a beginner new to big data analysis. I am glad that I got to know about the apache spark and learn it as a part of this course on the IBM Watson platform. will look forward to further modules.

Great course that covers some of the fundamentals of advanced data analytics. I use some of these techniques (like PCA) in my career for discovering defects in devices. This is a great starting course.

Concise course. Has its challenging aspects, but overall was clear. The best part is the programming assignment and tutorials: great hands-on introduction to IBM Watson Studio with manageable examples.

Nicely arranged course. However, both assignment on week 4 should be rechecked to make sure that it could run as exercise to student. Also, please make sure that the video is up to date and less error.

Very useful courses to take if you are beginner of data science. The course was not detailed enough sometime. But you will surely get a global view of IOT data analysis after this courses.

It's good but it really requires someone who knows and even master Spark Apache(+SQL fundamentals) so that you can follow and understand and take advantage of the course

Nice course. Learned the basics of a lot of different topics. Nice to do a large Data Science project in the last part. So you can apply all learned theory

Great Course but this would have been even a better course if more concepts and details were covered in it. Anyways, still a great course for beginners

A very nice introduction to Apache Spark and it's environment. As a bonus, it's also a very nice refresher to your basic statistics!!! Great course!

Its a great experience especially with this course. I appreciate Romeo the way he designed the assignments. It brings out the clear understanding.

A nice introduction to ApacheSpark on Python while learning about the fundamentals of Statistics and Dimensionality of data for Machine Learning

It feels really good when you get to learn something new and Coursera helped me to achieve something and learn something new and good.

Thank you so much coursera, I had great experience. as a feedback - try to improve your video quality specially 4th week videos.

Like a introductory course is good. It help me to understand the fundamentals of Apache Spark and remember statistics concepts.

great learning and thank you so much for great content for such topics. i loved this course and enjoyed a lot during learning.

I really like this learning method from IBM especially the instant quiz just to make sure I understand the important points.
