What do you mean by the the median has two equal parts? How do I find the answer to the problem below...

*The median hieght is 5ft 2in. How many students are 5ft 2in taller? How many are shorter?
**I already know the sum of the heights of the students in a class is 1,472.
***The mean is 5ft 4in. How many students are in the class? I got 21.4 for the answer. I think that this problem has something to do with the one above.

Median is Middle. There are just as many on each side, by definition. How many are above? Half? How amny are below? The other half.

How many students? 21.4?????!!!!! Who is the 0.4 Student? If you did not get a Natural Number, something went very wrong.
