thanks !!! sometimes my teacher explains things and I still don't understand...and I ask question and I still don't understand...then I don't worry because I know that when I get home I will have khan academy on my side.. You cause me to go from an 63% in math to a 97%..thanks your a life savor!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@seandafny]

maybe dont go to school then and learn from Khan Academy. that would make more sense than getting up every morning and ... well dont even get me started i am glad Khan Academy has helped

[@adupavasista3987]

[@shoebmohammad926]

Amber Hawkins: You are right sometimes our teacher fail to explain things which a student can understand. No matter how many times they try but their approach is nowhere to be able to understand.

[@nexisle7508]

I love you man. When you explain math its like you're explaining a story or something. You don't explain procedures, you explain both procedure and reasons. And because you use accurate terms for every specific situation makes me understand the real meaning behind each word. Man you're one in a million

[@chrisbkirov]

The whole playlist is great, but the last 20 videos (49-68) are simply amazing - clear, concise and very informative. Note: 57 should be between 53 and 54.

For many years, my family and myself, have used your channel. I find myself here; yet again. Thank you. I am getting so close to graduating with my Psychology degree. To get a better understanding, you just know how to use proper word choice and I am grateful for that. Thank you so much!

[@thedarkdiamond1207]

Thanks for making khan academy free for everyone. Khan Academy has better explained this compared to majority of my school.

Your explanation makes statistical concepts understandable and comprehensible. I used to have many fears and doubts in statistics...now I am more confident and enthusiastic to attempt to solve stats problems. Thank you Mr Khan, and god bless.

[@ChuneInKiki]

OMG, I actually understood that!! I was even answering questions before he gave the answer. That was fun, I never thought I'd say that about stats. I find this impressive since the last stats class I took was back in '95. THANK YOU , Can't wait to watch the other videos.

Funny how a playlist of videos is worth more time and money than going to a campus, in class. Sal is my real econ, biology, and statistics teacher. PatrickJMT was my real calculus teacher. Next time, I know to just do any math classes online and just look up these videos and not waste hours of my time and cause even more unneeded stress and indigestion. :/ Thanks, Sal!

[@bahrom7893]

So in his set: {1,1,2,3,4,4} , you can't just take the number in the middle, so you take two numbers in the middle and take the average: (2+3)/2 = 5/2 = 2.5 So if you have odd number of terms {1,2,3}, you just take the one in the middle -> 2 For even number of terms {1,2,3,4}, sum the two numbers in the middle and divide by 2, which is the same as finding the average of those two numbers -> (2+3)/2=5/2=2.5

[@utkarshtiwari1234]

Sal I really appreciate all the work you do. I am a Comp. Sc. Eng. Interested in maths and I consider Khan Academic my reliable and go to source for top notch educational content especially for maths. I have always feared maths and thought that I can’t do it, because I am not intelligent enough. But wen you teach it feels that its just my basics are not clear and once cleared, I can do it all. So thank you for this confidence that I get by learning math from you.

7:00 The most important takeaway from this video. "These are human constructs".

[@DarknessHowls]

Schools up until college are meant to equip you with a wide variety of skills so that, when you decide what you want to do in life, you have the solid foundation you need to pursue it. Plus, a lot of the skills you learn in school (especially elementary/middle school) DO come into play often in "real life". Without schools, how would we educate people? And if people weren't educated, how could humanity hope to advance its understanding of the world, or even hold on to its current understanding?
