变异系数(Coefficient of Variation,简称CV)是一个用于比较不同数据集或不同单位指标之间离散程度的统计学概念,它通
变异系数(Coefficient of Variation,简称CV)是在统计学中常用的一种度量指标,用于衡量数据相对于其均值的离散程度。它可以帮助研究人员比较不同数据集之间的相对变化情况,而不受其单位或尺度的影响。 在实际应用中,变异系数经常被用来比较两个或多个总体样本之间的离散程度大小。当样本均值存在差异时,如果仅仅依靠数据的...
coefficient of variation 变异系数(Coefficient of Variation):当需要比较两组数据离散程度大小的时候,如果两组数据的测量尺度相差太大,或者数据量纲的不同,直接使用标准差来进行比较不合适,此时就应当消除测量尺度和量纲的影响,而变异系数可以做到这一点,它是原始数据标准差与原始数据平均数的比。 CV没有量纲,这样就...
