When you talk about data science the most important thing is **Statistical MATHS **.

This course teaches statistical maths using simple excel. My firm belief is MATHS is 80% part of data science while programming is 20%. If you start data science directly with python , R and so on , you would be dealing with lot of technology things but not the statistical things.

I recommend start with statistics first using simple excel and the later apply the same using python and R. Below are the topics covered in this course.
