均匀设计在心理实验中的应用探讨

Uniform Design: Exploring Application in Psychological Experiment

均匀设计是一种由中国数学家王元、方开泰在1979年提出的一种新实验设计方法,保留并提高了正交设计的均匀分散性。实验次数等于处理水平数。均匀设计包括选择均匀设计表和安排实验等步骤。适合于探索性实验,特别适合于侦测多个因素（2-18个）的交互作用。不但能处理连续变量,还能处理离散变量。可以在心理实验中应用。

Uniform design was a new experimental design developed by Chinese statisticians, which developed from orthogonal experimental design. The characteristic Repetition of orthogonal experimental design was removed, but the characteristic Uniformity was remained and emphasized. The number of experiments equaled the number of treatments combinations. After the step of choosing right table of uniform design, it was the step arranging the selected treatment combinations. Uniform design was capable of dealing with number of experimental treatments in psychology, ranging from 2 to 18, especially in exploring experiments. Uniform design could deal with not only the continuous variables, but also the discrete variables.
