The normality of data from 50 CVs was tested through the Shapiro-Wilk test, and the mean (m), median, standard deviation (SD), maximum and minimum values, asymmetry and kurtosis were all determined using the momentum method. The CVs were ranked as low [CV < (m - 1 SD)], moderate [(m - 1 SD) < CV < (m + 1 SD)], high [(m + 1 SD) < CV < (m + 2 SD)] and very high [CV > (m + 2 SD)]. In summary, these data were close to the normality because the slight and flattened curve was skewed to the right. The CV’s mean was 11.08, the median was 11.94 and the standard deviation was 5.13%. Accordingly, values of CV ≤ 5.95% are low, 5.95 < CV ≤ 15.21% are moderate, 15.21 < CV ≤ 20.34% are high, and CV > 20.34% are very high. 2011 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303026597021 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
