A.
The lower extreme is an outlier, but the upper extreme is not
B.
The upper extreme is an outlier, but the lower extreme is not.


C.
Both extremes are outliers.
D.
Neither extreme is an outlier.

Answer 1

You have to find interquartile range, which is Q3 - Q1
Q3 = 41
Q1 = 36
IQR = Q3 - Q1 = 41 - 36 = 5

The outliers will be any values below 36 - 1.5 * 5 = 36 - 7.5 = 28.5 or above 41 + 1.5 * 5 = 41 + 7.5 = 48.5
Therefore, your outliers are : 25 and 45 (C)

Answer 2

wait..I messed up....outliers are 25 and that is all (A)

State whether each extreme in the data set is an outlier. http://static.k12.com/calms_media/media/1417500_1418000/1417707/1/bf04c7275efc9221a9a642622c43559107609bc6/FGA_130917_261030.jpg
A.
The lower extreme is an outlier, but the upper extreme is not.
B.
The upper extreme is an outlier, but the lower extreme is not.
C.
Both extremes are outliers.

D.
Neither extreme is an outlier

Answer 5

Q1 = 14
Q3 = 20
IQR = Q3 - Q1 = 20 - 14 = 6

Outliers will be below 14 - 1.5 * 6 = 14 - 9 = 5 or above 20 + 1.5 * 6 = 20 + 9 = 29.
So your outliers are : 2 and 32....both of them (C)

Answer 6

For the data in the table, the mean score is 15 and the median score is 14.

How are the mean and median affected when the outlier 42 is added to the data?

A.
The mean and median are not affected.

B.
The mean and median both increase by 3.

C.
The mean increases by 3, but the median stays the same.

D.
The median increases by 3, but the mean stays the same.

Answer 7

11,12,13,14,14,16,19,21,42
median is 14, it is not affected

mean is 162/9 = 18, it increased by 3
answer is C

Answer 8

Are the data shown in the line plot skewed left, skewed right, or not skewed? http://static.k12.com/calms_media/media/1417500_1418000/1417712/1/8b04e8e7d7f8c63b83187d00faf71c6cac668492/FGA_130917_261035.jpg
