一、前言应用各种随机排列設計所进行的試驗,其所取得的数据,一般都可以用方差(变量)分析法来加以分析。分析結果,如果处理間方差比F值显著,无效假說被拒絕,为求将判断落实到各个处理上,还可以进一步对各处理进行成对的比較,并作显著性测驗,以便对试瞼作出具体的結論。对供試处理作成对比較的显著性测驗法,过去习慣上采用t测驗法,也即所謂最低显 I. INTRODUCTION Using various tests of random alignment, the data obtained can generally be analyzed using variance (variability) analysis. As a result of the analysis, if the inter-process variance is significantly greater than the F value, the null hypothesis is rejected, and further comparisons may be made between the treatments for the purpose of applying the judgment to each treatment, and the saliency test may be made to make the test eyelid Specific conclusion. The test for the treatment of comparison made significant test, used to use t test, the so-called lowest significant
