Fig. 4

Between-method mean absolute differences in linear distances. Using the same data sets as described in Fig. 3, absolute differences in mm between replicates of the same individuals measured with different methods were calculated and averaged across individuals. Circles represent means and vertical lines are the s.d. Dashed lines indicate the mean within-method absolute differences. Numbers 1–24 correspond to the distances as described in Table 2. a) MED + HIGH; b) DIG + MED; c) DIG + HIGH; d) S2 + S3; e) S2 + S2/D2; f) S2 + S3/D2; g) S3 + S2/D2; h) S3 + S3/D2 and i) AL0.5 + AL1.0
