Об этом курсе

This course introduces you to sampling and exploring data, as well as basic probability theory and Bayes' rule. You will examine various types of sampling methods, and discuss how such methods can impact the scope of inference. A variety of exploratory data analysis techniques will be covered, including numeric summary statistics and basic data visualization. You will be guided through installing and using R and RStudio (free statistical software), and will use this software for lab exercises and a final project. The concepts and techniques in this course will serve as building blocks for the inference and modeling courses in the Specialization....

This course literally taught me a lot, the concepts were beautifully explained but the way it was delivered and overall exercises and the difficulty of problems made it more challenging and enjoying.

The tutor makes it really simple. The given examples really helped to understand the concepts and apply it to a wide range of problems. Thank you for this. Wish I could complete the assignments too.

Be sure you want to learn R before you embark on this course. As a beginner, it was a challenge, but after a few rounds of revisiting the content, it all started to make sense. I would recommend you do the exercises on R Studio. I did mine on Datacamp and had to refamiliarise myself with the RStudio platform for the final assignment, which was slightly painful as more things had to be set up (and time may not be on your side by then). You can use the commands learnt in the course for the final assessment but many classmates seemed to go above and beyond. Online resources are truly indispensable and I'm amazed that I can make decent educated guesses as to what certain lines of code do, in order to improve the chart!

Offers a good introduction to probability as promised. Great material, you can really tell that the teachers have made an effort making the content presentable.

The only thing I did miss however, was a lecture introducing coding in R especially since that is what makes up most of the time in doing the peer-reviewed assignment. Nothing fancy, just a single lecture introducing the logic behind the dplyr and ggplot2 packages would have been ever so helpful and could have been covered in less than 30 minutes.

Thanks for a good course!

The course is excellent. The only drawback it is the peer review assignments. After you finish your assignment you need search for peers to review your and ask at least three people to do this for you.
