The concepts of direct and inverse proportion lead to the location of points in the Cartesian plane by hyperbolic coordinates; the two coordinates correspond to the constant of direct proportionality that specifies a point as being on a particular ray and the constant of inverse proportionality that specifies a point as being on a particular hyperbola. Webdirect correlation: 1 n a correlation in which large values of one variable are associated with large values of the other and small with small; the correlation coefficient is between 0 and +1 Synonyms: positive correlation Type of: correlation , correlational statistics a statistical relation between two or more variables such that systematic ...
