Question

For the set {-12,-12,-4,8,16,20}, would each measure be affected if the value of 4 were included.

A mode • yes • no
B median • yes • no
C mean • yes • no
D range •yes •no

Answer 1

The mode would not be affected because there is no other value of 4, so -12 is still the mode.

The median would be affected because the median will be 4, rather then 2.

The mean would change from 8/3 to 20/7

The range would not be affected because 4 would not be the greatest or the least number
