变异系数（Coefficient of Variation, CV）是统计学中用于衡量数据离散程度相对于其平均值大小的标准化指标。其核心价值在于能够比较不同单位或量级数据集的相对变异性。以下是详细解释：
定义与计算
变异系数定义为标准差（σ）与算术平均数（μ）的比值，通常以百分比形式表示。计算公式为：
$$ CV = frac{sigma}{mu} times 100% $$
例如，若某数据集标准差为5，平均值为50，则CV=10%，表明数据波动幅度约为平均水平的10%。
核心特性：无量纲性
CV的最大优势是消除了数据单位和量级的影响。这使得比较不同量级的数据集成为可能，例如：

变异系数（Coefficient of Variation，简称CV）是统计学中用于衡量数据离散程度的相对指标。以下是详细解释：
变异系数表示标准差与均值的比率，通常以百分比形式呈现。它反映数据波动性相对于其平均水平的比例，适用于比较不同单位或量级数据集的离散程度。
$$ CV = left( frac{sigma}{mu} right) times 100% $$
总结来说，变异系数通过“标准化”标准差，提供了一种无单位的相对离散度度量，特别适合多维度数据对比分析。
