Bro this video was insanely clear and well explained. This helped me so much, so thanks man !!
video saved me. Thankful that you explained each number in the table as well.
Anyone have a stats final coming up?
Literally just saved my analysis coursework. Thank you so much
This is an excellent explanation. A real time saver. 🙂
Thank you very much! Concise, clear and well explained.
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!
thanks
Good explanation, where as my study book just provides the final answer instead of the calculation. THX!
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?
5:14 Why can't we use z statistic instead of t statistic?
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)

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

Oh.
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?

Doesn’t answer the question properly. Find another video and don’t waste 7 minutes here.
he gets to the answer 4:45 minutes into the video. the rest is not helpful.
