Hope you are doing well! I found out your channel just today! You've made statistics so much easier for me to understand!! I'm so grateful that you are so generous to share your knowledge and become more accessible! THANK YOU SO MUCH!!

This is simply brilliant presentation. So lucid.

It was very simple, clear and easy explanation. Thanks!!

Professor vB: Thanks so much for you fine videos.

Will you explain degree of freedom and hence derive the reason of n-1 not n-2 or n-3 etc.

Thanks for the nice video, the concept for going stretching the variance span of sample variance is understood but why is it specific with -1 and why not with other values like -2 or other numbers. Could you please enlight??

Sir please upload the video on numericals of electrodynamics (, written by David J Griffiths 4th edition)

Is it mentioned in question for population and sample

FatimaAbdullah-yukj

Why here you put sample and population values in same 😐
