Answer 1

put the numbers in order
12,14,14,14,15,16,16,18,18,19,21,22
Now find the middle number (the median). However, if there is an even number of numbers, there will be 2 middle numbers. So you just add the 2 middle numbers and divide by 2 to find the median.
add the 2 middle numbers....then divide by 2 ...(16 + 16)/2 = 32/2 = 16 (answer B)
