The answer is most likely going to be c

OpenStudy (hellokitty17):

thanks

OpenStudy (anonymous):

I agree

OpenStudy (anonymous):

Example: Let's say there was an outlier-20, and the smallest number 1

OpenStudy (anonymous):

20-1 would be 19

OpenStudy (anonymous):

which is bigger than it was before the outlier

OpenStudy (anonymous):

before the outlier it was 8-1

OpenStudy (anonymous):

which is 7, which is smaller than 19

OpenStudy (anonymous):

so C would be correct

OpenStudy (welshfella):

yes

OpenStudy (welshfella):

the median will stay the same
