Coefficient of Variation - Definition, Formula, and Example
WebCV is the ratio of within-person standard deviation and mean. ICC is the ratio of the true-score variance to total observed variance. We can rewrite ICC as a squashed version of the ratio of between-person variance and within-person variance. Let s ( x) = 1 1 + 1 x be a squashing function, let σ B 2 be the between-person variance and σ W 2 ... WebMay 27, 2024 · In statistical analysis, ... (CV) is a measure of the ...
