The power of univariable chi-square test will be lower, and explained test outcome will be affected by moving beginning and end point of cells. After then, some scholars have proposed various methods to raise power , and they does not affect by moving beginning and end point of cells. In this paper , we will consider the problem that a testing for two dimension’s uniform distribution ,and the outcome how to affect by moving cells. We will also propose new test statistic to compare with chi square ,and use analog data to prove and see that the new test statistic will be more accurate than chi-square.
