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)

For the most part I enjoyed this class and got quite a bit out of it. I do think there could be more examples shown and maybe even some "homework" given to work through some of the math needed. I did supplement this class with some YouTube videos. Most of those were by "The Organic Chemistry Tutor"

There is a lack of examples in probability lectures. It would be great If you add more examples in probability lectures. In order to pass the test I had to find more additional explanations and examples on the Internet. Generally, the course is well organized and other topics are explained very good.

The course is super good, definitely worth it for a beginner though at the last week it moves at a bit too fast base for a beginner, in general, it's a really good first step and a doorway to better understand and know what are the ways you can get information from data and what can you do with it.

Haven't done this math in 30 years. The general overview and PDF sheet were good. Required use of outside resources to understand units on probability, logarithms, change of base, and rate of growth of continuous processes. Extra time to do outside reading but glad to have learned this material.

Was a very nice intro into the math behind data science. The final chapter, (week 4) was not as well done as the first 3 weeks. The lessons seemed more hastily thrown together and failed to drive home the important sections. Would have been an easy 5 star but the last week was very disappointing.

The Math instructor was great! I loved all his lessons. The engineering instructor teaches this final few weeks. I struggled with his teaching style and his penmanship. But, the topics covered throughout the course are great! The course notes given I also found useful I will hold on to!

Learned lot of new things, I had to sometimes refer to the materials outside the course, but the course provided me with structured learning and helped me to learn the required things, Haven't started any machine learning course, so can't say how much of the course contents are applicable.

Some question has no answer. For example, the log in the test 2 that answer is -80/23. It can't be that because the number inside the log less than 0. There are some errors in the same tests, too, such as the answer 1.304. Furthermore, some question in the fourth test has some confusion.

The weakest coverage was definitely in the 4th week during the coverage of probability. One would be better off using youtube videos or another course as this overview was rushed and felt incomplete. The explanations and examples were just not up the standard set by previous weeks 1-3.

I would love to have much more exercises on each topic so I could practice more! Plus within the final quiz the final task is not clear - I've calculated both probabilities, but I cannot understand what it means - to assess one probability vs the other and get the numbers in answers.

The videos and class materials are great for introducing students to all of these concepts. However, there should be more ways for students to practice things that they have learned in this class. Some of the modules were especially difficult because of the lack of practice problems.

I learned a lot from this course, but the video walkthroughs for the last 2 weeks where hard to understand. I had to find other learning material that gave better explanations. I rate the course at 4 since the topics included are a good start for getting into data science math.

There certain things in the last week 2 videos that could be explained better and I felt like more formulas could have been derived for more multiple cases in the probability section. But although for basics it is a really good course. I will highly recommend it to everybody.

Even though this course seems to be simple to complete , the basics from this course are essential. All the Definitions of a Complex subjects are delivered through a simpler explanation. Reattempting the Quizzes results in knowing the areas where we have to concentrate more.

I want the resend of my certificate with change of name in it. Due to some technical problems o mistyped my name in the account created. Can you please rectify my name as Alina Vincent for the course Data Science Maths Skills I completed today and resend a fresh certificate?

Great fun brushing up all those basic skills! The quizzes were challenging. Additional reading resources might be helpful. Some later videos need a bit more explaining I guess. It might also be helpful to speed up the videos while the instructors are writing things down.

the lesson were really great and the practice quizzes were even better. In fact, i failed for the first time on the quiz of probability. But it felt like some lesson, especially related to the Bayes theorem was a bit rushed. Other than that, it was really great course.

it's a brilliamt course with well made lectures. I would've rated it 5 star but the Bayes' theorm part, the explanations were not clear, more breakdown was needed to clear up alot of confussions. Regardless, it's still a great course and i'd reccomend it to everyone.

It was a great course, I really believe that I learned a lot. However, I have to say that the last part about probability I did not find it very easy to understand as the other 3 so, I had to search for more information outside the course, that is why I give 4 starts.

All in all, I Iiked of the explaining style of the first instructor but It is not covered deeply the topic especially probability. The explaining of the probability was not sufficient to grasp the fundamental of the subject. Irrespective, it is a fine course to take.

An all in all easy course to follow for the first three weeks, however the last week could have been more elaborated since that touches upon the most important concepts of probability. Rest it is a good course for anyone to brush up his or her mathematics skills.

Is a great course for the most part. However, as it gets toward the more complicated concepts there are expanding holes in the explanations and the homework. Students enrolling in this course need to be ready to teach themselves more as the material progresses.

This was an interesting course. The first few modules were good for reviewing some skills and thinking about them in a new way. I was glad the course also included an introduction to Bayes' theorem, I've always been curious about what it was and how it was used.

Great content except for Week 4. Wish the whole course were taught by Professor Bendich, he does a great job of explaining the concepts and adding a touch of humor. Overall, satisfied with what I learned yet extremely frustrated with Probability and Statistics.

Good course and well explained material with thoughtful questions that test your knowledge. Lost a star due to some of the tests having poorly formatted questions with regards to rending some of the mathematical functions which makes the experience frustrating.
