No it's not the same. Consider these numbers: {50,1,2,3,4}. The average
(50th percentile I believe is the same as average) = (50+1+2+3+4)/5 = 12.The median however is the element in the middle which is 2. You can see the clearly differ alot. The median is usually preferred above the average when you expect to have extreme values (like the 50) and you don't want to weigh them as much. When you have an even amount of numbers the median is the average of the 2 middle numbers.
