## À propos du cours

Data science courses contain math—no avoiding that! This course is designed to teach learners the basic math you will need in order to be successful in almost any data science math course and was created for learners who have basic math skills but may not have taken algebra or pre-calculus. Data Science Math Skills introduces the core math that data science is built upon, with no extra complexity, introducing unfamiliar ideas and math symbols one-at-a-time. Learners who complete this course will master the vocabulary, notation, concepts, and algebra rules that all data scientists must know before moving on to more advanced material. Topics include: ~Set theory, including Venn diagrams ~Properties of the real number line ~Interval notation and algebra with inequalities ~Uses for summation and Sigma notation ~Math on the Cartesian (x,y) plane, slope and distance formulas ~Graphing and describing functions and their inverses on the x-y plane, ~The concept of instantaneous rate of change and tangent lines to a curve ~Exponents, logarithms, and the natural log function. ~Probability theory, including Bayes’ theorem. While this course is intended as a general introduction to the math skills needed for data science, it can be considered a prerequisite for learners interested in the course, "Mastering Data Analysis in Excel," which is part of the Excel to MySQL Data Science Specialization. Learners who master Data Science Math Skills will be fully prepared for success with the more advanced math concepts introduced in "Mastering Data Analysis in Excel." Good luck and we hope you enjoy the course!...

This course syllabus is great. It starts wonderfully. Week 1 to 4 is taught by Paul Bendich, and Daniel Egger the instruction is awesome. Effective way to refresh and add the Data Science math skills!

Effective way to refresh and add the Data Science math skills! Thanks a lot! At the time of the study some of the quizzes content were not rendering correctly on mobile devices (both iPad and Android)

This course was pure garbage. Though it seemed promising in the beginning, it was clearly too ambitious and poorly designed. The topics are too quickly covered, and don't build upon each other. It's a very disconnected learning experience. The probability modules are completely useless. The "instructor" just read some definitions and sloppily wrote some formulas on a virtual whiteboard. Though I appreciate the exposure to a wide array of topics, my time would have been better spent reading a book on the same concepts - an exercise I will inevitably now have to do.

T​he course is divided into 4 weeks. Topics in Week 1 and 2 are explained very well. But Week 3 and Week 4 are just useless. There is no teaching in Week 3 and Week 4, just writing down the formulas present in texbooks.

T​he reason anyone wants to take courses like this, online is to understand how the formulas shown in text books work and have a deeper understanding of the topic.

B​ut unfortunately the topics in Week 3 and Week 4 were just presented as it would appear in a text book, no teaching there.

I chose this course because it said it was for beginners but the content was extremely difficult and was not at a beginner level at all. The presenter assumed knowledge and the presenter himself made errors during his presentation and did not explain concepts well. The quiz was very difficult to attempt because the questions often went beyond what was in the course. Do not attempt this course if you do not have actuarial science level.

I expected much much much more than what I was exposed to in this course. The video companions could be more detailed, having more examples (I believe math is learnt via examples) and the lectures, especially in the third and fourth weeks were amazingly disengaging.

Why didn't i get certificate? I have tried a lot to get this one, i have lost sleep for many nights. Im coming from a poor family. I dont have enough money with me. If i get this certificate it will help for my career.

Help me sir..

I think this is not the best course to start with for the data science learning path. The first half was maybe too easy and the second half was hard and confusing. It's discouraging for a person who is just starting with data science.

The course was not properly taught. There should have been more quizzes, more systemic approach to explaining the problems and solutions. Also the feedback after exams and quizzes were non existent

The course provides very basics concepts of Mathematics and Statistics.This course would help those who needs fundamental acquaintance with basic theorems of Mathematics and Statistics.

j guess I would be better suited to a course for pre-beginner beginner levels. This has been over my head since the first video.

First, its too easy, almost intuitional. Then it overwhelms you with a plethora of formulas, no mathematical logic provided.

very poor instructional videos. videos and examples in videos are extremely hard to follow and not well-organized.

Found too many errors in both content and quizzes. Good basic course for beginners. But, the errors must be fixed
