Question

@ganeshie8

Answer 1

the residual differences of each data y-value minus the corresponding predicted y-value from the line of best fit for all values of x.

Answer 2

Danielle: Could you be more specific in stating what you're looking for here? Numerical values? explanations? or ... ?

Answer 3

residuals but someone here helped yesterday on those and my lesson said incorrect :/ but I want to learn how to find them

Answer 4

place points on the graph to best represent the residual differences of each data y-value minus the corresponding predicted y-value from the line of best fit for all values of x.

Answer 5

Danielle: That's still not specific enough. What have YOU done so far on this problem, and specifically what kind of assistance do you need and want to proceed further? Your most recent post is OK as far as it goes, but it's still up to you to get started (asking questions if necessary) before expecting responses from potential helpers.

Answer 6

Im not expecting responses I just want to know how to find the residuals

Answer 7

Residue = Observed Value - Predicted Value

Answer 8

In your graph, dots \(\color{blue}{\bullet}\) represent the observed values

line of bestfit represents the predicted value

Answer 9

When x = 1,

observed value = ?
predicted value = ?

Answer 10

18-14?

Answer 11

Actually, the residual is the DIFFERENCE between the observed and predicted value.
You've typed in 18-14. What's the value of that, and what does this value represent (what's its name)?

Answer 12

4 and it represents the residual?

Answer 13

Yes, I guess you need to find the residuals for all the dots in the given graph !
such pain !

Answer 14

lol yeah tell me about it -.-' there should be a website that does it for you but I don't think that miracle exists lol

Answer 15

is it correct?

Answer 16

when x=24?

Answer 17

check the residues when x = 7

one of them is wrong

Answer 18

oh and what about when x=2 and x=3? do I have to put dots on the lines or not

Answer 19

Hey wait, my mistake
your work looks perfect! all correct!

Answer 20

oh ok lol

Answer 21

and what about what I asked for x=2 and x=3?

Answer 22

Oh that is wrong

Answer 23

we don't have any observation at x = 2

Answer 24

x = 3 has a residue of +6 right?

Answer 25

omg yeah I got confused and placed it on two
and this program you have to start over to erase -.-'

Answer 26

Have fun :)

Answer 27

no kidding lol xD

Answer 28

and are you sure that for x=2 it shoudln't be 2,0?

Answer 29

Yes, we don't have any observations at x=0 and x=2
so no question of residue arises

Answer 30

but then why did we use the values from the line on top of the dot and won't use it for two?

Answer 31

when x=2, whats the observation value ?

Answer 32

2-2

Answer 33

How ?

Answer 34

ok lets put it this way, for x=3 we used the value from the line 18 even though it didn't have a dot

Answer 35

but why don't we do the same for two and mark it as 2-2=0 therefore 2,0

Answer 36

makes sense now?

Answer 37

When x = 3, we have a dot at y = 24

Answer 38

yes exactly but there is no dot on the line

Answer 39

When x = 3,

observed value = dot = 24
predicted value = 18

Answer 40

oh wait nvm I was overthinking nonlogical stuff sorry

Answer 41

so fingers crossed and hopefully this one is correct :)

Answer 42

good luck!

Answer 43

and is incorrect again :(

Answer 44

Oh, maybe try putting 0 as residue when x = 2 and see

Answer 45

no is for the 3 value.......

Answer 46

how is that even possible

Answer 47

when x = 3, the residue is 6 right ?

Answer 48

yes even the hint tells me so...dont worry I sent a complaint

Answer 49

Okay

Answer 50

they said the answer was 6,6

Answer 51

but then when you look at the comparison below it it says 3,6 im soooo mad right now
