The data set below has an outlier 2,10,10,11,11.12,12,12,13,14,14

Which value is changed the most by removing the outlier

Answer 1

Mean

Explanation:

The mean with the outlier is

(2+10+10+11+11+12+12+12+13+14+14)/11 = 11

The mean without the outlier is

(10+10+11+11+12+12+12+13+14+14)/10 = 11.9

The median is the middle number

With the 2 it is 12

Without the 2 it is 12

Mode is most often

With the 2 it is 12

Without the 2 it is 12
