This page will provide an introduction to understanding and using library call numbers. Each book in the library has a unique call number. A call number is like an address: it tells us where the book is located in the library.
Definition of Correlation: Correlation is a statistical technique that is used to measure and describe the STRENGTH and DIRECTION of the relationship between two variables. Correlation requires two scores from the SAME individuals.
The coefficient of restitution (COR) is a measure of the restitution of a collision between two objects: how much of the kinetic energy remains for the objects to rebound from one another vs. how much is lost as heat, or work done deforming the objects. The mathematics were developed by Sir Isaac Newton in 1687.
