《安徽农业科学学》1964年第3期发表了白湖农场试验站写的《农业科学试验研究数据的统计处理方法》一文。这篇文章涉及的范围很广,在两套资料结果的显著性检验一节中,谈到如果需要研究的是所得一套资料结果的平均数与另一套资料结果的平均数比较,这有两种情况:(1)对于无成对关系的样本;(2)对于有配偶成对关系的样本。但对这两种情况究竟如何区别,说的很不明确,文中说:“例五中的两肥料试验如分别在几个不同试验地区(土壤肥力等彼此差别大)进行,则有配偶成对关系。”那么,在同一试验地区,或不同试验地区而土壤肥力等差别不大的,是否就不可能有配偶成对关系的样本呢?这种说法,不但不明确,而且有同题。一度风行的对比法设计(即每品种或处理与对照紧靠,相邻种植)的几次重复,是在同一块试验地,而且土壤肥力差别不大,听得资料正是配偶成对关系的样本。如以“几个不同试验地区”及“土壤肥力等彼此差别大”作为配偶成对关系的条件,恐怕是没有根据的。此外,也有人认为,同一试验中的资料就有配偶成对关系,也值得商讨。根据“百家争鸣”的方针,作者针对这个问题提出自己的看法,说的不一定对,请广大读者与白湖农埸试验站讨论和指正。
“Anhui Agricultural Sciences” in 1964, No. 3 published White Lake Farm Experimental Station written “agricultural science experimental research data processing method” article. This article covers a wide range of subjects. In the section on the significance test of two data results, it is mentioned that if one needs to study the comparison between the average of the results of one set of data and the average of the other, Two cases: (1) for unpaired samples; (2) for paired couples. However, it is unclear exactly how the two situations differ from each other. In the article, they said: “The two fertilizer tests in Example 5 were carried out in several different test areas (soil fertility and the like differed greatly from each other) Relation. ”Then, in the same test area, or different test areas and soil fertility is not much difference, whether it is impossible to have a sample of spouses paired? This not only is not clear, but also the same title. The once-popular comparative design (that is, each repetition of each cultivar or treatment in close proximity to the control, adjacent plantings) was on the same site of experimentation and there was little difference in soil fertility, and the data were spuriously paired sample. It is unfounded that the conditions of the paired relationship between spouses, such as “several different test areas” and “great differences in soil fertility, etc.” may not be justified. In addition, some people also think that the data in the same trial have a spouse’s pairing relationship, which is also worth discussing. According to “a hundred schools of thought” approach, the author put forward his own views on this issue, that is not necessarily right, please readers and white lake farmer test station discussion and correction.
