Question

The table below shows data from a survey about the amount of time, in hours, high school students spent reading and the amount of time spent watching videos each week (without reading):

Reading Video
3 1
3 2
4 3
5 4
6 6
7 7
10 8
12 8
14 9
30 15

Which response best describes outliers in these data sets?
Reading has a suspected outlier in the 30-hour value.
Reading has a suspected outlier in the 30-hour value, and video has a possible outlier in the 15-hour value.
Neither data set has suspected outliers.
The range of data is too small to identify outliers.

Answer 2

So first, it's good to know what an outlier is. Do you know what it means?

Answer 3

An outlier is a piece of data that is far away from the other numbers.
Ex. 1,2,1,3,4,3,2,1,60. ^0 is very unlike 1,2,3, and 4, and far away from them which makes it an outlier.

Answer 4

Just glancing at it, you can eliminate C and D, as 30 is definitely an outlier.

Answer 5

Do you think 15 is an outlier too?

Answer 6

yes

Answer 7

Answer 9

Well, it's so close to 9, I personally would disagree.

Answer 10

30 is 16 away from 14, while 15 is only 6 away from 9. Therefore, I would just choose A.

Answer 11

oh so just 30 ?

Answer 12

is a "Suspected outlier"?

Answer 13

Yup. That's would I would choose.
