One of the most critical aspects of the data science approach is our perception of getting the information processed. In developing insights from our accumulated data, we dig out the possibilities. And those possibilities are known as statistical analysis in Data science.
Statistics acts as a tool to gather, extract, analyze, and review data, which is an input to Data science techniques; hence, learning statistics is a baby step toward becoming a data scientist. Great Learning‘s Statistics for Data Science course is for beginners and professionals who want to upgrade their skills in data science domains and learn everything about statistical analysis.

As practicing design engineer in West Cost medical industry, I find Professor Dr. Sarkar way of explaining the most complex subject in a practical approach very rewarding and helps in right metal representation for long term understanding. Although I have taken similar courses in Stanford paying close to 2K plus USD came out even more confused and even gave up statistical approach . Thanks for sharing for free and hope this benefits the transition from Excel based modeling to Python and would highly recommend to any one working with data and design.

I actually had a doubt in the regression line explanation, there we take, where we minimized the sum of [Y(i) - (a - b*X(i))]^2 to get a and b and thus calculating our required line. But why didn't we minimized the sum of square of perpendicular distance. As in Let us say Slope = b, then the perpendicular distance will be [Y(i) - (a - b*X(i))]/sqrt(1 + b^2). And summing of squares of these distance we differentiate to get a & b. Thanks for this lecture, very insightful

I wish I could have had a statistics teacher like this.

Dr.Sarkar is truly awesome! Please share this video with your peers so that everyone can learn from the best. Also do subscribe to our channel so that you get a notification of our upcoming videos

[@sandhyasunkula4263]

I am really impressed with his lecture. Very apt analysis on each concept. Thanks for uploading it on KZbin. Could you tell me the statistics book name he was holding at 57th minute of the lecture?

[@greatlearning]

Hey! Thank You. We are glad you found it helpful. The book he is referring to is Business Statistics by Prof.P.K.Viswanathan

1:49:07 @ Great Learning It is because we have two eyes on a horizontal line. left and right are assosiated with horzontal directions. switching of left and right is about how our eyes interpret the directions. So mirror image swithces the left and right, not the top and bottom. If our eyes were vertically aligned, the top and bottom would have switched in mirror. top and bottom orientations of objects are not affected by the horizontal alignment of our eyes. The relative positions of the top and bottom parts of objects remain the same in relation to our eyes and the mirror. Therefore, we do not interpret the mirror's reflection as reversing the top and bottom directions.

Just bcz of the reason of spoon feeding explanation with experiences, the Indians are rocking at silicon valley. Hats off to his presentation skills with real life illustrations.

[@sweetvoilet]

Dr. Sarkar, I bow to you. :-) You are such a fantastic teacher. Many statisticians have knowledge but only handful like you can explain the concepts so beautifully and make them approachable. After listening to you for almost 6 hours, I can hear your voice everywhere now. lol! especially when I am reading difficult subject matter! Note: as I am watching this in 2024 and after going through covid, the comment made by a student at 6:03:01 about the possibility of an epidemic which he thinks is rare hit hard. Edit: I am done with the course in about 3 days. I never enjoyed statistics this much even when I was in college and now I do! I have new appreciation. Thank you Dr. Sarkar and the awesome folks at great learning for making this available for free. 🙂

Wonderful lecture, cheers to the professor.

[@ganesanarumugam7190]

Great lecture. Can you please upload next level of statistics video? Also, it would be helpful if you could upload basic and advanced mathematics video which are required for Data Science, Machine Learning and Deep Learning. Looking forward for next set of videos :)

[@greatlearning]

We are working on it. We will upload it soon. Please do share the video and subscribe to our channel.

Makes immense sense coming from the land of Indian Statistical Institute Calcutta. The institution know for CR Rao and the University of Calcutta alum.

amazing teaching... Thank you!

[@sciencelearnerscorner2112]

Great courses without Great Professor s it is impossible to learns about real worlds problem experiences.

[@akshaykrgupta88]

Kudos to the Professor. Unarguably one of the best videos on statistics. Refreshed the concepts in one go and in such an unambiguous manner!! Although, is this a Stanford class in USA? Can see only Indians :P
