平均数往往是试验资料的代表值,这在第二讲中已经阐明,但是一般试验所得到的平均数,常是样本计算的结果,如产量、新梢生长量或其他某一性状的指标.因此这就有一个问题,即所算得的样本平均数是否能代表其总体的产量或新梢生长量呢?就必须用统计方法进行分析,其分析过程就称为显著性检(测)验. The average is often the representative of the experimental data. This is clarified in the second lecture. However, the average of the average test is usually the result of the sample calculation, such as yield, shoot growth or other indicators of a certain trait. Therefore, there is a question as to whether the calculated average of the samples can represent the overall yield or the growth of shoots. Therefore, the statistical analysis must be conducted. The analysis process is called the saliency check.
