## 課程概述

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!...

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 is neat little course to revise math fundamentals. I generally find learning probability a little tricky. This course helped me a lot in better understanding Bayes Theorem. Thank you professors.

Easy and suitable for beginners with high school math skills. If how the equations are deduced are introduced, it would be even better.

Good materials. But examples from learning sections are a lot easier than problems in quizzes. More difficult examples would be great.

Week 1 - 5/5

Week 2 - 4/5

Week 3 - 3/5

Week 4 - 4/5

A good introductory course which could do better in explaining some concepts clearly.

Every data scientist needs to know some statistics and probability theory. The amount of math you'll need depends on the role.

Thanks,

It's a excellent course with all of the basic concepts to start in the Data Science World.

Great regards and thank you for the course.

It was a good course for a beginner.But I think the proportion of the course allocated to probability is much less than it deserve.:)

Very comprehensive and challenging - I feel a final quiz would be great but individually, very well though out content and questions

Though that this course was too simple but actually it is quite an eye opening and refreshing for the last two topics. Well done!

its very good course,,but i didn't mark 5th star because course need more excercises on each lesson special at probabilities

Jul 28, 2017

Thanks for course! Only advise I can give - change the name to "Basic Math Skills for Data science". Course is pretty easy.

Dec 04, 2017

It is very good course but need to add more exercises (examples), reading materials in addition to more and longer videos.

Oct 25, 2019

Well-described concise notes and if you do not understand anything, the author provides written notes with every lecture.

Good introduction course. It will be better if more contents and examples for calculus and probalility can be provided.

Jun 22, 2017

Quality instruction with clear explanation of concepts and relevant practice/test modules to check your understanding.

Apr 18, 2018

no discussion or ongoing grade at least in the beta course. Generally pretty good, a little slow and simple to start

Feb 10, 2018

Clear structure and typical case were applied in this course. However, hope the course material could be more detail.

Jan 01, 2018

The course is helpful both as a refresher and a introduction, although i would like to have more practice exercises.

Mar 21, 2017

Material was well presented. Exercises could have been more involved; likely would have enhanced the learning.

Mar 20, 2019

The course is well structured and good for the newbies and the ones who are not from mathematics background.

Jun 25, 2018

I wished there were better examples and a little more in depth videos for week 4 since week 4 was very tough

Mar 14, 2017

Good course. I feel like Week 4 could have been explained slightly better but otherwise I really enjoyed it.

Aug 25, 2017

Great course. For me the linear algebra part is too easy. But really learnt a lot about Probability Theory.

Nov 27, 2017

brushed up the basics of mathematics good course for beginners and want to revise the key skills of math.

Sep 25, 2017

Please make probability sessions more interactive so that it will be useful to understand basic concepts.

Apr 21, 2017

at time the formulas are given without proof or intuitive explanations. overall a good basic level course
