• CORRELATION
  
  The degree of relationship between two sets of data. A correlation near plus 1, called a positive correlation, indicates that changes in one set of data are closely related to changes in the other set and that the data sets change in the same direction. A correlation near minus 1, called negative correlation, indicates that changes in one set of data are closely related to changes in the other set and that the data sets change in the opposite direction. A correlation near zero indicates little or no relationship between the changes in the two sets of data.
