详情----------Details----------
These data have been introduced by Yates (1935) as an example of a split-plot design. The treatment structure used in the experiment was a 3 x 4 full factorial, with three varieties of oats and four concentrations of nitrogen. The experimental units were arranged into six blocks, each with three whole-plots subdivided into four subplots. The varieties of oats were assigned randomly to the whole-plots and the concentrations of nitrogen to the subplots. All four concentrations of nitrogen were used on each whole-plot.
这些数据已经出台耶茨(1935年),为分裂图设计的一个例子。实验中所用的治疗结构是一个3 x 4三个品种的燕麦和四个氮浓度,全因子。试点单位安排到6块,分为四个次要图的三个细分整个图。燕麦品种被随机分配到整个图和氮浓度的次要图。每个全图上使用所有四个氮浓度。
