About the Course

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 was mostly review for me though probability especially Beyes Theorem derivation was new. The instructors provided clear often refreshing ways to look at material.\n\nThank you for a great class!!

Overall course is good. Last two graded assignments are challenging. But lectures should have more solved examples to deal with assignments.

I liked the course.

The fourth week was not specific enough and not covered entirely . Also the professor should consider using widely accepted scientific notations in probability

The second part was difficult for me because was short on examples and not as dynamic as the first two weeks. But overall I would say that was a nice beginning

Another course on how to apply Bayes-Miller to something other than coin flips and card drawings is needed. The transition to real-world problems is the issue.

the very last week was tough

beginner of data science will not understand. that probability things is really hard to understand without some basic illustration.

Good content, but the explanations will be able to improve, i know that at last week the subjects are complex, but i found better explanations in other sites.

Good as an introductory course. It got challenging by the end, but I did enjoy it. Definitely need more study to be done to be comfortable with these topics.

The initial material is very introductory but the later does get much harder. A combination of the lectures and notes provides a good coverage of the topics

From these course your basic concept of mathematics will improve and anyone can apply in these course. It is easy as non mathematics person can also learn it

Pretty decent. I could've used some clearer explanations on the statistics stuff, but that's likely due to the fact that I've had no previous exposure to it.

The lecturer and content are good. However, I don't find that the content was really useful as a separate course. It is still short and good as a refresher.

Until the Probabilty everything was great. The given info and test were even however after that information given became unsatisfactory and unexplanatory.

Its a good review of the concepts I studied in my high school but it is certainly not enough to dive right into data science after completing this course.

Very good math review but the probability lessons need improvements. I had to study probabilities from external ressources in order to pass the quizzes.

The Last exam was very tricky and hard. I found it very interesting. Thank you for making this course. I appreciate this as well as many people like me.

They gave real life examples to explain the topics which is very good .. personally it helps me to understand the core fundamental logics of each topic.

Actually I don't know well whether these contents should be earned by video classes. But, the explanations and the passion of the instructor were great.

The course is good for beginners. Although, more emphasis could have been placed on industrial examples but still the course is a great start for anyone

an essential course for them wants to learn data science. But last week become really tough to understand, though the experience was good.

Thank you.

it was nice and understandable course specially the probability part .. for a basic data science it is enough to cover all mathematical portion.. :)

very good content and quality, however, the explainations could sometimes have been presented better way (the blackboarding could have been better).
