Fig. 2 Coefficient of variation (CV) values: (A) logCV for raw tracings and photographic tracings; (B) untransformed CV for raw tracing and photographic tracings. The box-ends show data quartiles; the bar between them is the median; outliers are plotted as stars if they are more than 3 interquartile ranges outside the quartiles, and as circles if between 1.5 and 3 interquartile ranges outside the quartiles; the “whiskers” go out to the most extreme observations that are not plotted separately as outliers. Abbreviations: p, planimetry; d, digitizing; raw, raw tracing; photo, photographic tracing; 1, Session 1; 2, Session 2.

Fig. 3 Mean values: (A) log means for raw tracings and photographic tracings; (B) untransformed means for raw tracing and photographic tracings. The box-ends show data quartiles; the bar between them is the median; outliers are plotted as stars if they are more than 3 interquartile ranges outside the quartiles, and as circles if between 1.5 and 3 interquartile ranges outside the quartiles; the “whiskers” go out to the most extreme observations that are not plotted separately as outliers.
