在行-列设计中，实验单元按两个方向分组，即使用两个区组因子，一个因子代表设计的行，另一个因子代表列。例如，在农业实验中，设计的行和列可能代表不同的施肥时间和方法。在偏好测试实验中，列可能代表不同的受试者，行可能代表向受试者呈现不同产品的顺序。在胰岛素反应实验中，行、列和治疗可以分别代表个体动物、注射日期和胰岛素水平。在所有这些实验中，希望通过消除行和列因素的影响来提高估计治疗比较的准确性。
In row—column designs the experimental units are grouped in two directions, i.e. two blocking factors are used with one factor representing the rows of the design and the other factor representing columns. For instance, in an agricultural experiment the rows and columns of a design might represent different times and method of application of fertilizers. In a preference testing experiment, the columns might represent different subjects and the rows the order in which different products are presented to the subjects. In an insulin-response experiment, the rows, columns and treatments may represent respectively individual animals, date of injection and levels of insulin. In all these experiments it is hoped that there will be a gain in the accuracy of estimating treatment comparisons resulting from eliminating the effects of the row and column factors.
