Question

Given the following values which point would be considered an outline?

X: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9
Y: .8 | 2.1| 3.1 | 3.8 | 5.2 | 8.4 | 6.9 | 8.1 | 9

A: (2,2.1)
B: (4, 3.8 )
C: (6, 8.4 )
D: (9,9)


I think it would D.

I am right ?

Answer 1

<b>I don't think so.</b>

Let's take the average slope. Or, if you're not up for that, let's graph the points.

Photo(remove the spaces): h t t p : / / p r n t s c r.c o m / i s 4 m z b

I drew the line of best fit for you. By definition, an <i>outlier</i> is <b>"a value that "lies outside" (is much smaller or larger than) most of the other values in a set of data."</b>

So, what point doesn't belong here? What point "lies outside"(is much smaller or larger than) most of the other values in this data set?

Answer 2

Ooh ok...I see. Than it would C? Because I'm thinking that 6 isn't close to 8.4.

Answer 3

Correct!

Answer 4

Yay :D thank you
