#* Add the left and right numbers together then divide by two
 
#* Add the left and right numbers together then divide by two
#* Example: In a data set 1,2,3,4,5,11,11,12,14,20 the number is in the 2.75th position which is between the 2nd and 3rd numbers meaning we take (2+3) then divide by 2 which equals 2.5
