About the Course

Despite the recent increase in computing power and access to data over the last couple of decades, our ability to use the data within the decision making process is either lost or not maximized at all too often, we don't have a solid understanding of the questions being asked and how to apply the data correctly to the problem at hand. This course has one purpose, and that is to share a methodology that can be used within data science, to ensure that the data used in problem solving is relevant and properly manipulated to address the question at hand. Accordingly, in this course, you will learn: - The major steps involved in tackling a data science problem. - The major steps involved in practicing data science, from forming a concrete business or research problem, to collecting and analyzing data, to building a model, and understanding the feedback after model deployment. - How data scientists think!...

Very interesting course. It shed a light on what the structured approach really is. It's worth to pause for a moment with every step of the methodology and think how to apply it in real life. Thanks!

I think it's a little bit vain to introduce in such way for some people without much background in statistics and machine learning .

The course has delivered basic understanding of the flow, but

1)No clear images in videos

2)This could have been more interesting.

Not a complicated course which gives you an accurate, intuitive and useful methodology applicable to any Data Science problems.

Lectures were informative but slow. Need to be more engaging to keep interest ongoing.I dozed off during certain lectures.

Some of the lectures were not very clear. This grading is based on a comparison with other courses in this specialization.

For me this part was a little too much descriptive and given example (hospital patients) is not very easy to understand

Very generic and superficial explanations. Needs more substance. The best thing was the explanation of the ROC curve.

IBM python online exercises were difficult to complete because of faulty online implementation. Content seems dated.

Overall is good, except the example of heart disease was too complicated to transmit clearly the idea of this course

This course is more theoretical than practical which kinda makes this course a little boring then the other courses.

Interesting, even though there are a lot of theoretical lessons, and many times they require an extreme attention

A good simple yet essential course to establish a mind set on how to deal with data problems in an organised way

The final assignment was a bit vague probably due to the choices of subject we were allowed to perform this on.

a la herramienta externa le hace falta un entorno mas amplio para que se pueda aplicar los recursos aprendidos.

very shallow course. Better that two courses before, but still no real knowledge learnt, no skills practiced

By Milena S

Too complex of a case study to understand stuff. Also, too boring and theoretical and very less interactive.

The content is good, but there are a lot of typos and mistakes in the lessons and the assignments/quizzes.

This course was more organized the others, however, it needs to provide its student with more definitions

It was ok. Definitely one of the weakest of the cert. Instructions were vague for the final assignment.

presentation slides are poorly prepared, images used either not in the original size or bad resolution

A simple example to explain the course would have been more beneficial for a wider audience I believe.
