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 ?

I don't think so.

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

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

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?
Ooh ok...I see. Than it would C? Because I'm thinking that 6 isn't close to 8.4.
Correct!
Yay :D thank you
