Grades are normalized on a gaussian curve.

What's the difference between mean and median in a Gaussian distribution?

Looking forward to your contributions to mathematics.

Are we talking about grades? Honestly when I see "50% of doctors are below average" I intuitively think of some other metric, such as the correct/incorrect diagnosis ratio, or the number of people that died because of their errors. Maybe it's just me but their uni (?) grades never comes to my mind.

It alludes to the joke: "what do you call the last student from the worst medical school? A doctor"

Median is a type of average.
