The variance analysis showed that differences of each drought resistance index among the 13 varieties were extremely significant , then the single factor multiple comparisons between two varieties were calculated 方差分析结果显示, 13个树莓和黑莓品种在每个抗旱性指标上均差均极显著。
In statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values. Errors in inference, including confidence intervals that fail to include their corresponding population parameters or hypothesis tests that incorrectly reject the null hypothesis are more likely to occur when one considers the set as a whole.
