Least square method is extremely useful in practice. In order to reduce the influence of error on the least square question, by making use of orthogonal array, this paper constructs a method for least square question to obtain it's stable approximate solution with the experimental design. And using some examples to jllustrate the result is better than that of the ordinary least square solution.
