The Learn By Example: Statistics and Data Science in R course is taught by a former Googler with a Stanford education and a top analyst with degrees from IIT and IIM. Both of them have extensive real-world expertise in analytics, e-commerce, and quant trading. The course provides a thorough introduction to Data Science, Statistics, and R using examples from everyday life.
It begins by explaining fundamental ideas like the mean, median, etc., and finally covers every facet of a career in analytics or data science, from processing and analyzing raw data to presenting the findings visually. Examples from real life, case studies, and R source code are used to illustrate each idea. The examples span a wide range of subjects, from A/B testing in the context of an Internet company to the capital asset pricing model in the context of quantitative finance. The course is usually available for INR 1,499 on Udemy but you can click now to get the Learn By Example: Statistics and Data Science in R Course for INR 499.
Who all can opt for this course?
- MBA graduates or business professionals seeking a move into a position that requires a strong mathematical background.

Featured Review
Pushpendu Talukder (5/5): The way Trainers are explaining the concept of statistics using R is awesome. I had my hate-love relationship with statistics during college days and work life. This is the first time in my life that I am really understanding the significance of statistics and can relate to real-world situations.
Pros
- Jerry Bernardi (5/5): For me, it was a great review of statistics along with an introduction to R.
- Jerry Bernardi (5/5): I feel that the course material is great and the teaching style is very enjoyable.
- Micah Shull (5/5): Excellent course! Lots of valuable information is presented in an easy-to-digest format.
- Robert H. Woodman (4/5): This is a good refresher course for statistics, and it is proceeding at a good pace.
Cons
- Vlad Mitroi (2/5): They mix up formulas all the time, making things rather confusing instead of ..well, teaching.
- Vlad Mitroi (2/5): All in all, I hope i’ll get a refund due to the (lack of) quality of this course.
