Definitions

the degree of relationship that is shown to exist between one thing and another. Positive correlation is the increase or decrease occurring simultaneously between two random statistics. When both statistics simultaneously go up or down there is a possibility that they are both being affected by a common cause. Once the correlation between statistics has been noted, statistical management can isolate the factors affecting the statistical change. Negative correlation is when one stat goes up and another goes down simultaneously. In this situation there is also a possible common cause.
