标准差

In two-rowed barley, the lowest standard deviation of main spike length was 1.02, and the highest of the single plant spikes was 39.75.

在13个供试的二棱野生大麦中，主穗长标准差最小为1.02；单株小穗数的标准差最大为39.75。

By preliminary experiment, we analyzed the credibility, validity, difficulty, discriminate validity and so on, and statistically analyzed the testing score by average value, standard deviation, test of normality.

进行预试验，分析护理标准化病例试卷的信度、效度、难度、区分度等，并对学生考试成绩进行平均分、标准差、正态性检验等统计学分析。

However, under the default model the standard deviation of the loss of the loan is a bit more than the one which deviates from the average value of the loan under the Credit Metrics model;

不过，违约模型下贷款损失的标准差要比Credit Metrics模型下的贷款价值偏离其均值的标准差要大些；
