2.1
9.1
8
7.4
________________________________________
I'm not sure because I was taught that an outlier is either too high or too low so it doesn't fit in the data.

Answer 1

Well because if you notice that 0.9 is close to 1, and 2.1 is close to 2, 3.2 is close to 3, 3.9 is close to 4, but 7.4 is not close to 5, and 5.8 is close to 6, 7.2 is close to 7, 8 is close to 8, and 9.1 is close to 9. Do you see the pattern? 7.4 is the outlier.

Answer 2

so..its 7.4?

Answer 3

D is 5, 7.4 is right

Answer 4

Its D guys

Answer 5

Weird... I got it wrong. The right answer was 7.4 O.O

Does anybody understand why? I don't.

Answer 6

7.4 is correct because notice how if you put this on a scatter plot, all of the numbers are nice and smoothed out, however, 5 with 7.4 is really far out making the answer D

Answer 7

Definitely 7.4

Answer 8

Did you look at the date when the question was asked??? dude 2013

I'm sorry, I didn't notice that. Thank you for bringing that to my attention.

Answer 10

it's weird, all right. 7.4 is the median. Surely not an outlier.
