what does median mean...?

median is the middle number when u put them in order from least 2 greatest

Or...
a median is a line drawn from a vertex of a triangle to the midpoint of its opposite side.

Another name for the median in statistics is the 50th percentile, indicating that 50% of the scores have a value above the median, and 50% have a value below.

I hope this helps a litle more. Thanks for asking.
