The midpoint (also known as class mark in relation to histogram) is the middle point of a line segment. It is equidistant from both endpoints. The formula for determining the midpoint of a segment in the plane, with endpoints (x_1, y_1) and (x_2, y_2) is

left(tfrac{x_1 + x_2}{2}, tfrac{y_1 + y_2}{2}right).

In three-dimensional Cartesian space, the midpoint formula is

M=left(tfrac{x_1 + x_2}{2}, tfrac{y_1 + y_2}{2}, tfrac{z_1 + z_2}{2}right).
