It is cool to have Khan Academy, 3Blue1Brown and all those content creators but sometimes you just want something straight to the point, thank you JB

Great video man. I'm a math major and find probability times more confusing than any course I have taken lol. It doesn't help that our professor only has one tone to his voice, lol. Always nice to have a clear explanation of this material. Thanks!

I took so many stat classes at some point even tutor others, but never come a cross some one who can clearly explain this counter intuitive subject. Indeed, knowing a subject and teaching others is too different things. Thank you sir for sharing your knowledge to the world. As some one who love to learn and teach others, I am very grateful to find your videos.

Months of missing classes and procrastinating before WACE exams has led me up to this point. Thank you so much!!!

Watching one of your videos makes me understand ten times more than reading the textbook, and your content is better than any other statistics-related videos on youtube. Thank you for uploading this and helping me pass my exams!

Thanks for this amazing video. Clear to the point and very informative. I dont get why lecturers are unable to meet the quality of free YouTube content

Awesome video thanks for posting. I was very confused when my text book showed E(X-E(X))^2 but you explaining that the second E(X) is the mean "μ" was a huge help.

This video helps me to understand far much better than 3 hours statistics class. Unluckily, found this just only a night before test. 😔
