Abstract: A method of analyzing a correlation among four variables in a two dimensions configuration and a computer accessible medium for storing a program thereof are provided. The method comprises providing a plurality of data comprising a first variable, a second variable, a third variable and a fourth variable. The first to the fourth variables have correlations. Then the data are marked in the two-dimension configuration according to the first and the second variables. The group correlation is marked according to the third variable. The character of the fourth variable is shown by a predetermined method in the two-dimension configuration according to the fourth variable.
