I think this is a very good explanation. The mathematics behind PCA is beautiful. However, this explanation is all you need. ❤

I have a question:
Let's say I want to calculate the PCA of children's grades at school to know how it impacts the final grade average of each child. For that I have my sample, which would be all the children in a class, for example. Then I have the grades of those children in different subjects such as Math, History, Physical Education, etc. And I also have the average. Do I add the average as another variable to the PCA analysis? Or should I make a correlation, for example, between PC1 and the average and see the PCA loadings?

Thanks for the video, this really explains it in a nutshell! This may be not in your alley, but what would PC2 to be if you would plot geochemical data with each variable being an element (PC1 seems to be rock type). Thanks in advance!

A big thank you!! I have this topic in my semester exams, and everyone around me is mugging up, upon asking what it is actually, they give me definitions that do not satisfy me, this single video clears a lot in understanding PCA. I wish I had a teacher like you in my college.

I am now convinced that there are no tough subjects, only ineffective tutors. I have been struggling to understand this concept for over 3 years, and here I am, within 11 minutes things have fallen into place.
An expert not necessarily be a great teacher. There might be great experts assigned in educational institute to teach such concepts.
But someone like you is what we need in our schools and colleges (expert and well articulated).
Simplicity is the utmost form of sophistication.

Thanking you from the bottom of my heart.
Keep on helping people like us.

Perhaps another video on how to do it in R will be great hit.
