LANE STEPS

The midpoint. If eighty-one patients were treated with drug XYZ, and the time for white blood cell counts to recover following this treatment ranged from two to sixty days, after you rank the patients by the number of days required for their white blood cells to recover, the median is the number of days that it took patient number forty-one's white blood cells to recover.

Strip of land that separates the lanes of opposing traffic. Alternately, the midpoint in a range of numbers.

In geometry, a median of a triangle is a line joining a vertex to the midpoint of the opposite side. It divides the triangle into two parts of equal area. The three medians intersect in the triangle's centroid or center of mass, and two-thirds of the length of each median is between the vertex and the centroid, while one-third is between the centroid and the midpoint of the opposite side.
