The statistical mean can also be used to interpret statistical data. Some important properties make statistical mean very useful for measuring central tendency. Since Xi - X is the distance from a given number to the average. The numbers to the left of the mean are balanced by the numbers to the right of the mean.
In review, vertical angles are angles formed by the intersection of two lines while alternate interior angles, alternate exterior angles, corresponding angles and consecutive interior angles are formed by the intersection of two lines and a transversal.
Coordinate Geometry. In another branch of mathematics called coordinate geometry, the points that define a line are located on the plane using their coordinates-two numbers that show where the point is positioned. For more on this, see Definition of a Line Segment (Coordinate Geometry) . If we know the coordinates of the two endpoints of a line segment, we can calculate the distance between them, and so find the length of the line segment. See Distance between two points (coordinate geometry).
