t值测定法适用于两处理均数间差异显著性的比较。然而,农业试验中常常需要进行多个处理均数间的相互比较。为了适应这种需要,统计学家根据不同情况提出了一些设计分析方法。本讲座只介绍三种常用方法,即(1)一向变量分析法,(2)随机区组试验的设计与分析,(3)裂区试验的设计与分析。前两种属于单因子试验,后一种属于复因子试验。
The t-value method is suitable for the comparison of the significant differences between the two treatments. However, agricultural experimentation often requires a comparison of the mean of multiple treatments. In order to meet this need, statisticians put forward some design analysis methods according to different situations. This lecture introduces only three commonly used methods, namely (1) the method of always-variable analysis, (2) the design and analysis of randomized block experiments, and (3) the design and analysis of split-zone tests. The first two belong to the single factor test, the latter belongs to the complex factor test.
