Avg mid-term score is 82.5 and y hat is 81.87 which is closer to the actual 81.9. So the calculation is perfect. And if we can round off 81.87 to 81.9 then its a perfect prediction. Thank you for the detailed calculation steps.
I didn't. All this was written by me. If you need a calculator to calculate the regression, then look for any TI calculator that does statistics - then look for regression. You might find some online calculators that can do it for you.
When you find the linear equation then you plug X, in this case X-bar which is 87 and then you have an answer Y from the equation which is 86.27. So, you input 87 and then the output is 86.27. The idea is that the equation will predict an answer when you plug in 87. So, to predict the final exam score, you put 87 and then the predicted value is 86.27.

Watching this while about to have an exams in 4 hours
Its helpful indeed
Thank you!!
Saves My ass..... Will keep on Bunking to learn here :P
how did you get 1.1 for b i kept typing in the equation exactly how you did but i get like 140
Please could you tell me which software have you used here!? And how you are writing in the board?

Confusing but very helpful
Thanks a lot
What kind of software are you using here to draw your notations?
It’s called Doceri an app on a tablet.
handwriting is pretty
why aren't you using ur decimals? my x bar is 82.5 but you use 825 ... won't that affect the answer ???
i don't know where a and b functiong come from

You said X is the mid-term score. So its average is 82.5, but you said avg mid-term score is 87. How come?
