Am. Malina & Buschang, in Malina, 1995; 29. It might be expected that error between two or moreobservers should be greater than that obtained for within-observer error, since systematic between-observer biaswould contribute to between-observer measurement differ-ences. This is due to variation insome biological characteristic of the individual being mea-sured, which results in variation in the measurement; even ifthe technique used is exactly replicated each time. http://www.scielo.br/scielo.php?pid=S1517-86922005000100009&script=sci_arttext&tlng=en
It has a widespread and important place in nutritional assessment, and while the literature on anthropometric measurement and its interpretation is enormous, the extent to which measurement error can influence both Metab. Similar observations were made about R.
R and %TEM are related through the coefficient of variability (CV). Possible errors are of two sorts; those that are associated with: (1)repeated measures giving the same value (unreliability, imprecision, undependability); and (2)measurements departing from true values (inaccuracy, bias). For the recruitment of these children we selected three schools (one of medium-high socioeconomic status, one of medium socioeconomic status and one of medium-low socioeconomic status); this represents the childhood population Technical Error Of Measurement In R Kinanthropometry in Aquatic Sports: A Study of World Class Athletes.
Ulijaszek and D. How To Calculate Technical Error Of Measurement In Excel To assess the intra- and inter-observer variability of the measurements taken in the course of the study, two sub-studies were carried out: one at the beginning and one at the end Clin. In cross-sectional studies a proportion of the totalvariance for any group measure of nutritional anthropo-metry observed is due to measurement error.
In Figures 1 and 2 we show the Bland-Altman plots for different anthropometric measurements and indices, in males (Figure 1) and females (Figure 2); mean differences were close to 0, except Define Technical Error Of Measurement Table 2(a) shows correlations of anthropometricmeasurement means against TEM, for girths, lengths, andskinfolds, respectively, from data collected by Ross et al.(1994) on elite athletes. This is of potential diagnostic value,since most child survival, health and development pro-grammes involve regular growth monitoring (Tomkins,1994) and/or monitoring of nutritional status using anthro-pometry (World Health Organization, 1995).

However, the type of balance, stadiometer and measuring tape used in our study were standard and required little or no calibration.

Tables Table 1Anthropometric measurements in both sides of the body in prepubertal children Table 2Body composition assessed by anthropometric measurements in both sides of the body in prepubertal children Table 3Agreement Subjects and method Subjects One-hundred and sixty-four children (97 boys and 67 girls) aged 7-9 y were studied. In the case of a measurement with an R of 0⋅95,95% of the variance is due to factors other than measure-ment error.
Finally, comparisons of anthropometric characteristics between participants in our reliability and cohort studies indicated that the former had slightly, but significantly, higher weight, arm and hip circumferences compared to our cohort The choice between alternative anthro-pometric measures cannot rest purely on the basis ofmeasurement error, since different measures give differentinformation. Abstract Objective: To analyze the impact of choosing the left or the right side of the body on the anthropometric measurements and derived nutritional indices, in prepubertal children.Design: Cross-sectional pilot nutrition Both circumferences were calculated to the closest 1 mm using a non stretchable, flexible vinyl Gulick measuring tape.
