Bro this video was insanely clear and well explained. This helped me so much, so thanks man !!
Anyone have a stats final coming up?
video saved me. Thankful that you explained each number in the table as well.
Literally just saved my analysis coursework. Thank you so much
This is an excellent explanation. A real time saver. 🙂
I think that watching your videos can give a lot of people more...faith that they will do well on their tests. 😎
But in all seriousness, I love Khan Academy!
Thank you very much! Concise, clear and well explained.
This was a good video, but how can I calculate the standard deviation for a regression? Or calculate SE for a regression coefficient? Is that the same as standard error of estimate?
Good explanation, where as my study book just provides the final answer instead of the calculation. THX!
thanks
shouldn't the caffeine intake be in axis Y and time studying in axis X?
no because time of studying depends on caffeine intake not vice versa (y depends on x)
@@QueenOfMettall make sense! I guess both are correct.
@@theforester_ I mean yes you could also look at if students drink more coffee the more they study, it depends on how you phrase the question and what you are looking for :)
5:14 Why can't we use z statistic instead of t statistic?
I am super lost. It's been YEARS since I took a math class and I need to know how to investigate the uncertainty of an allometric equation. Can anyone help me or direct me to material that will give me a better understanding about how to do this?
no i cant help with that

YEAH I LUV KHAN ACADEMY
Why.Not the last bit.
Sry. I'll stop now
No I'm just saying "Why" not telling you to stop.
IDk. Also, my friend opened up 4 tabs of a maths Khan Academy video, and played them all at the same time.
Believe me, it sounded like something very, annoying.
I just did it for no reason :P
