I’m in an online Elementary statistics class, and currently we have a final project with vague directions that do not make sense. Figuring out what I needed to do in the first place was difficult enough, but having no assistance from the professor in completing the project besides “you’re overthinking it” hasn’t been helpful. This video has quite literally explained what he tried to explain in an hour long video is 6 f*cking minutes. Some people should not be teachers, but you’re definitely not one of them. Thank you so much.

Thank you so much, I reallly hope no else has had a similar situation as I have this semester, but if you do then you know the struggles of having a class with a professor who does not do lectures (all open book). Channels like these make all the difference and I cant thank you all at HelpYourMath enough!

Can we multiply the value of Ex with b1 directly in the equation of y??
Like
y=bo+b1x???
Ty
You are very welcome!
Thank you.
You're welcome!
What if one of the weight (x) = 0, the XY supposedly 0 right ? But if i use xy=0 my resukt are different with the solution provided in the test.
what about that x from b1x.. doesnt that x have a value that we will multiply b1 with...if so, how do you get that x value
If it's a homework problem, x value should be provided.
Please can you solve this for me?
The following table includes the gross national product (X) and the demand for food (Y) measured in arbitrary units.
Year: 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2019, 2020
X:6, 7, 8, 10, 8, 9, 10, 9, 11, 10
Y:50, 52, 55, 59, 57, 58, 62, 65, 68, 70
i. Specify and estimate the food demand function and give an economic meaning of your results
ii. Compute the Rsquare and find the explained and unexplained variation in food demand, interpret your results
III. Compute the standard errors of the regression estimates and conduct tests of significance at the 5percent level of significance
my teacher literally refuses to help me with this.. thanks so much man
You are very welcome!
Mine kept saying refer to Chapter 4 I was like 😑
How would it work if I only have an x and y table, like no table for xy, x^2 and y^2
It's just easier if you have xy, x^2, and y^2.
Coefficient determination?
underrated video
Thank you!
you explained so good, but for b0 48-(1.667).(30) I get a different answer.......1.667 X 30=50.01, then 48-50.01= -2.01 am' I doing it wrong???
No I got the same
How would I graph a regression equation?

sir how to find k value
He just cooked it easily 😮

the mental math is absurd
What does the n stand for?
number of pairs
Number of years
How many entries made for age....5 entries. That's n
Number of data all data that you have like N= 1,2,34, and etc
N = number of value
Sorry to pop your Bubble but 1.667×30 is actually not 35.001 in 5:00
Let me explain
You said 1.666 repeating is just 7/6
So if I multiply 7/6 to 30 it'll be
7/6×30=210/30
210/6=35
So in a sense it's 35 but kinda ok cuz it's kinda a rounding error. But my point here is that the answer could be more cleaner if we used 35 instead of 35.001
where's the part one?

Oh yeh bro what country
Which book this example or refrence give
Mike Tyson!?
?
Nonsense 🗑️ - didn't even calculate x in the end ( the hardest part) rubbish🚮🚮🚮
How did u get X2 values
