RESIDUALS! What are they? how to find them, how to use them

How do you calculate a redisual?
How do you find an actual value given the residual?
What is a residual?

[@chriso1185]

Man, you should be teaching at university level. Unfortunately, mathematics is one of the leading reasons why people change majors or drop out. You really bring the energy to this stuff.

[@luisfelipe3789]

OMGGGG I SERIOUSLY WISH YOU WERE MY TEACHER!!!! EXTREMLY HELPFUL! THANK YOU

[@kavitakakkar5726]

[@tesstossterone]

Thank you! I have googled all this and then just needed to know about the residual, if only I found you before the rest of it! Thanks for making it all so very simple : )

[@annaalbert4836]

[@thamir21]

How did you get 65? How do you calculate the real y value via equation rather than graph??

[@BFlood4471]

You're a trip.. If there we're more teachers like you we'd live in a better educated, world.

[@samandacam]

My math teacher thinks your hot and makes us watch your videos in class, please give her a shoutout or something to Katie Bye it will be awesome. Cheers :P

[@Jackjohnson762]

I wish my teacher would just play videos of you teaching instead of him even attempting..

[@elijahanca1828]

Thanks this helped me so much but I still don't get the reason for residuals and why we need to know them

[@godislove9920]

I guess it is somewhat of a test of your accuracy in making a line based on your predictions

[@riteshajoodha4401]

This guy is awesome :D

[@TheBoBuilder]

Nice! Thank you

[@cheerforluv3789]

bro. you saved my life. thank you ap stats jesus

[@l_t_truth_seeker]

Thank You Sir

[@readogamer3515]

Sir hats off

[@exkalina]

So if we already know the actual y then why do we use regression?

[@23MzSmith]

i wish you were my teacher!! i have a monotone lazy teacher which explains things in dumb ways.

[@lithuaniaboy123]

Where did you get the number 10 from?

[@catwheel1]

DJustaK thats the y intercept

[@goodvibings3566]

Let e1, e2 . . . , en be the residual values for the simple linear regression model Yi = β0 + β1xi + εi for i = 1, 2, . . . , n. Using the above model equation, explain why residuals can be used to estimate the unobserved values of the errors ε1, ε2, . . . , εn.

[@superjosereborn2]

Hahahahhahahahahaha. OMG this was awesome! Thanks a bunch!

[@islomkadirov222]

just perfect

[@alwaysatthefair]

Awesome

[@marycchavz]

If we already know the actual score for Joe, why do we need to predict it in a model?

[@MrFunsized1]

[@godislove9920]

[@gamingwithgill923]
