|coefficient of deviation;[數]變異系數；變動系數；變更系數
變異系數（Coefficient of Variation, CV）是統計學中用于衡量數據離散程度相對于其平均值大小的标準化指标。其核心價值在于能夠比較不同單位或量級數據集的相對變異性。以下是詳細解釋：
定義與計算
變異系數定義為标準差（σ）與算術平均數（μ）的比值，通常以百分比形式表示。計算公式為：
$$ CV = frac{sigma}{mu} times 100% $$
例如，若某數據集标準差為5，平均值為50，則CV=10%，表明數據波動幅度約為平均水平的10%。
核心特性：無量綱性
CV的最大優勢是消除了數據單位和量級的影響。這使得比較不同量級的數據集成為可能，例如：
應用場景

變異系數（Coefficient of Variation，簡稱CV）是統計學中用于衡量數據離散程度的相對指标。以下是詳細解釋：
變異系數表示标準差與均值的比率，通常以百分比形式呈現。它反映數據波動性相對于其平均水平的比例，適用于比較不同單位或量級數據集的離散程度。
$$ CV = left( frac{sigma}{mu} right) times 100% $$
總結來說，變異系數通過“标準化”标準差，提供了一種無單位的相對離散度度量，特别適合多維度數據對比分析。
