About the Course

Whether being used to customize advertising to millions of website visitors or streamline inventory ordering at a small restaurant, data is becoming more integral to success. Too often, we’re not sure how use data to find answers to the questions that will make us more successful in what we do. In this course, you will discover what data is and think about what questions you have that can be answered by the data – even if you’ve never thought about data before. Based on existing data, you will learn to develop a research question, describe the variables and their relationships, calculate basic statistics, and present your results clearly. By the end of the course, you will be able to use powerful data analysis tools – either SAS or Python – to manage and visualize your data, including how to deal with missing data, variable groups, and graphs. Throughout the course, you will share your progress with others to gain valuable feedback, while also learning how your peers use data to answer their own questions....

The specialisation and course states that this is suitable for beginners, but I would NOT recommended this for beginners. Support for coding in Python and SAS are limited. The course jumps to teaching you pandas and numpy without covering basic coding principles. Hence, it would be beneficial if you have some coding experience in either software. Also, some of the questions that pop up during the videos are unrelated to what the video is teaching, and if you get it wrong, there is no explanation given.

It is too small and shallow. Whole specialization is actually one full course split into 4 tiny parts.

This course is not suitable for beginners at all. I started studying with great enthusiasm, but it is very difficult to learn without help. Every lesson I had was very nervous. It shouldn't be like this. Unfortunately, I have to admit that I am not coping and am leaving this course.

This course didn't talk too much about data management and visualization, which made me feel quite disappointed. And you couldn't feel you could practiced what you learned in the course in the assignment. Most part of the assignment just focused on making some comments.

Totally just marketing materials! Don't waste your time with this school at all! You cannot learn a program in a couple of minutes!
