I hope very much that you'll look up "box plot" and learn how to identify the  the lower quartile, the median, and the upper quartile of a set of data points.  I know this material thoroughly, but think you'd benefit more from researching this problem and trying a solution yourself first than from simply accepting my explanations and answers.
