Question

The data points below represent the number of completions

Answer 1

@agent0smith

Answer 2

To find the residuals, just subtract the y-value on the line, from the actual y-value (the dot)

Like the first dot is y=18, the line is y=14, so the residual is 4.

Answer 3

oh and for the one that goes higher

Answer 4

and how do I plot them?

Answer 5

The same way you'd plot any other point. The x value is the same, the residual would be the y value.

Answer 6

so the first residual would be x, 4?

Answer 7

so the first residual would be x, 4?

Answer 8

Yes

Answer 9

alright thank you

Answer 10

what about the one that has the three dots

Answer 11

im confused about that one

Answer 12

I already have 1,4
3,6

Answer 13

Just find the residual for each and plot each. They all have the same x value.

Answer 14

can you give me an example of the one with 3 dots?

Answer 15

Find the residual the same way you found the other two. Three points is no different to one.

Answer 16

y-value of the dot minus y value of the line

Answer 17

so 20-18-17?

Answer 18

Find each residual one at a time.

Answer 19

that is what confuses me and that is why I asked for one example :/

Answer 20

It's no different to the others. When finding the residual of one dot, you can ignore every other dot.

Answer 21

geez just give the user an example ! IS IT THAT HARD?

Answer 22

and then there was no typing...

Answer 23

It's really not hard to ignore the other dots and find the residual for one dot at a time.

Answer 24

that is why I asked 20-17=3
then for the third dot would it be 3-18?

Answer 25

sorry 20-18=2 and then 2-17?

Answer 26

The residual is the y value of the dot minus y value of the line.

You don't then continue to subtract a residual value from another dot's value. They are three completely separate residuals.

20-20

18-20

17-20

Answer 27

that is what I was asking from you to explain

Answer 28

agent. your explanations are no me gusta

Answer 29

I don't know how you got the idea to subtract residuals. "To find the residuals, just subtract the y-value on the line, from the actual y-value"

Answer 30

ok now that I understood that part I need to understand what would happen to the dots outside of the line

Answer 31

Not sure what you mean.

Answer 32

is this good so far?

Answer 33

The ones at x=6 are all negative.

If you subtract the y-value on the line, from the actual y-value, you'll get negatives for any points that are below the line.

Answer 34

but I followed what you said for the first one 18-14=4 you never said 14-18=-4

Answer 35

subtract the y-value on the line, from the actual y-value

I assume you're reading this correctly. This means:
y-value of dot - line's y value

Answer 36

oh wait I confused it with th 3

Answer 37

ok so i changed them to -3,-4,-5

Answer 38

good?

Answer 39

Yes but you seem to have forgotten the residual for the point in the very top right.

Answer 40

what is wrong with it

Answer 41

It isn't there

Answer 42

oh lol but I don't see what is the x value for it?

Answer 43

Look at the graph, you forgot one

Answer 44

oh ok 8,4

Answer 45

8, 5

Answer 46

yeah lol so is that it?

Answer 47

Yeah the rest look fine I think

Answer 48

ok thank you @UsukiDoll you agree?

Answer 49

You're welcome.
