WebNov 23, 2024 · I don't see any special value to averaging coefficients of variation (CVs). Ideally your CV is consistent across datasets or groups or variables in which case you can underline that fact by citing a narrow range. Conversely, if your CV is not at all consistent an average is not informative and how to get it a secondary issue. WebJun 27, 2024 · where γ is the common coefficient of variation and γ 0 is the hypothesized value.. This statistic is compared to a chi-square with \( \sum_{i}^{k}{n_{i} - 1} \) degrees of freedom. The most common usage is the case for a single group (i.e., k = 1). The two sample coefficient of variation tests whether two distinct samples have equal, but …
