中文摘要:昆虫学定量分析资料常有2类不同性质的百分率,即组成的百分率和独立的百分率。在进行差异显著性检验时,如果样本数n较大,则组成百分率可用标准正态变量μ检验。作者给出一个简便的计算公式:μ=n0.5|P1-P2
英文摘要:There are two different kinds of percentages in entomological research which are proportions and independent percentages. For statistical test of a difference between two constituent ratios, if the number of samples is large enough, one can use the standa
