This is ordinal scale, which means you can rearrange it by 
Bad, average and good.

Because there are even number of variable the median will be n/2 and (n+1)/2.
That is the 5th and the 6th which are both average hence answer is average.

(Bad, bad, bad, avg, avg, avg, good, good, good, good)

For nominal scale we have only mode.
Ordinal scale means there is some order like good bad average or sizes, small large medium etc so median and mode can exist but not mean.
