Answer:
Find the number in the middle
First list the number from smallest to greatest
6,8,10,10,12,14,14,16,16,18,18,20,20,22
Find which one is in the middle
16 and 16 are the two middle numbers. There is two middle numbers because there is an even amount of numbers
If there are two middle numbers find the average
Do (X+Y) / 2
16+16 = 32
32 / 2 = 16
16 is the median for your score
Do the same to your friend's score
2,8,8,10,10,10,12,12,12,12,14,14,14,16,16
12 is the middle because there is 7 numbers to the left and right so 12 is the median.
Your score is greater by 4 because 16 - 12 = 4.
Hope this helps
