This would be: 0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6
Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.
If you are left with one number, that is your median!
If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)
In this case, you are left with one number, 2, so 2 is your median. I hope this helped!
I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
