Question

Look at this set of 10 numbers:

3 3 5 3 8 7 9 8 9 1
By how much would the median decrease if the number 3 replaced the number 7 in the set?

Answer 1

It would decrease by 2 going from 6 to 4

Answer 2

the median of the 10 numbers would be
(8+7)/2 so 7.5
if 7 was replaced by 3 it would be
(8+3)/2 = 5.5
so it would decrease by 2
