Answered by Ms. Sue
Your first answers are right.

What is the outlier for the second one?

Answered by Marko
the outlier is -16 for question 2
Answered by Ms. Sue
Yes.

-10/8 = -1.2

Eliminating -16, the median is ?



Answered by Marko
eliminating -16 would be
12 -6 = 6 for the mean
Answered by Ms. Sue
Nope.
Answered by Marko
eliminating the -16 would be -6
-1
-3
-2
= -6

so 12 - 6 = 6 as mean w/o -16 outlier
Answered by Ms. Sue
6/7

Answered by Marko
,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
