-15

-12

-19

0

-20

-14

the outlier is 0

the mean with the outlier 0

is: -13.33

the mean without the outlier 0

is: -16

is this correct?

next one:

4

-1

-16

2

0

-3

6

-2

for this i added positive got: 12

i added negative and got: -22

do i do 12 - 22

Your first answers are right.

What is the outlier for the second one?

the outlier is -16 for question 2

**Ms. Sue**, Tuesday, September 27, 2011 at 10:28pm
Yes.

-10/8 = -1.2

Eliminating -16, the median is ?

eliminating -16 would be

12 -6 = 6 for the mean

Nope.

**Marko**, Tuesday, September 27, 2011 at 10:46pm
eliminating the -16 would be -6

-1

-3

-2

= -6

so 12 - 6 = 6 as mean w/o -16 outlier

6/7

- Mrs. Sue Algebra outlier/mean recheck -
**Marko**, Tuesday, September 27, 2011 at 10:54pm
,857 is the mean

i messed up

12 + -6 = 6

6 /7

= .857

i forgot a step thanks again and again

.857 is the mean without outlier -16
