Rubbish

bro makes up some fire puppy names on the spot

The short answer is, it's arbitrary. Created, like all math. That said, there is reason for it. He references some at the end, but otherwise is demonstrating what the ^2 does mathematically instead of absolute value. Not a "deep" video, but I got my answer actually. So thanks.

Thanks man. Your previous three or four videos together with this video have helped me a bunch to understand the logic and roots of Linear regression. Thanks a bunch,😀 friend.

Thorough explanation. Helpful. Thanks!

Awesome

outstanding explanation.

I was taught that three lines on an equals sign means "always equal to" so I definitely wouldn't use it for anything to do with algebra or variables

You forgot a very important usage of the subscript and superscript: sequence enumeration, example: A^(4)_(n=1). Sequence A, with a superscript of 4, and subscript of n=1, means that sequence A start from the element 1 and goes to element 4, so a total of 4 elements in the sequence. This doesn't directly tell you what the actual elements are, just how many of them are there and their ordered locations in the sequence. Another usage is interval notation, the subscript tells you where the interval starts, and the superscript tells you where the interval ends. [F]^(4)_(1) says the function F from x=1 to x=4. Logarithms can also use subscripts, like log_2 (x) where 2 is the subscript, read: log base 2 of x So it's very important to know the context of the problem at hand, because math often reuses the same notation in multiple places for different proposes. People who first wrote those notations were't thinking of the newbies, it's like math gatekeeping lol

the reliebility of this video comes from the use of a sharpie

This is golden... Thanks a whole lot!

Bastard

Subscribed just because of bellyrubs😊

that's the worst tutorial I ever had to see in my life

Saved me

In the end you didn't explain why we used sqaured deviation. Please change the title of your video.

Why don’t you use a real graph

Entry of puppy is amazing 😀.

So the title of is a question that u suppose to answer it and explain it , but all you said is "a guy said so " , that by one of the useless video I watched

the explanation was great, thanks

Great video. 1 question: what data do you use to calculate the position of the trendline?

Bruh how many times are you going to misspell subscript

This is shit

I never took maths past the age of 16, turns out you need it to do a science degree, you just saved me yet another embarrassing question. Thank you!

Why choose 4? what is your basis?

So standard deviation penalizes the outliers more than the mean absolute deviation. Thanks for making this video!

I have to gently agree with others here. I like the video, but it fails to explain why standard deviation is being used over the MAD. Good video - misleading title.

didn't get my answer but it was nice

Misleading video title. 6min read gave me enough understanding / acceptance of the use of squared deviation here www.semanticerror.com/why-do-we-take-squared-values-of-difference-instead-of-absolute-values-while-calculating-variance/

Ok this is a total click bait. Make me mad a little bit. This should be re title as What is variance.

you are excellent, I watched the complete series. a lot of thanks to you june. hopefully you make more videos on all types of regression.

At last got the perfect solution!

if you have , for instance, X sub1, and X sub2, are they not considered to be like terms? thank you

This was a very helpful video.

I don't understand a word you're talking about...I am in 9th grade and I just wanna understand subscripts in mathematics because I saw this line in a book "a(variable) subscript n(variable) is not equal to zero" and some more crap so I just wanna understand it☹

The simple answer is because I told you so? oh my

I can teach you why beacaus your such an idiot

Thanks - very helpful and to the point

why you forget the "r" everytime

thank you :)

Brilliant explanation!

you didnt calculate the fucking standart deviation with the 2 methode sbecaussse i want to khow if both of theme give the same result or not fuuuuuuuuuuuuuuuckeeer 13min of nothing

Dear sir , why did you use the word "around " while defining Variance ? (Variance is howmuch a population varies 'around 'the mean) why not use 'from' the mean?

Just now wasted my 13.44 mins

Thanks for the honesty. Seriously. Most teachers just try to give me BS reasons and it’s annoying.

Thank you. Everyone else has been giving me BS answers like “absolute value is hard to undo”. nonsense like that. I expected it was something like this. Thank you for the honesty.

2:35 He gets to the point...

Wonderful Sir helped me a lot. Keep up the good work

How can you come up with a random line? You should choose the line with minimum variant

So three years later June should be sleeping about (365*3)*.5 hours a night?
