The Canadian Forces carried out an anthropometric survey for which the results were published in 1998. In order to evaluate the precision and accuracy of the measurements performed in the survey, an error analysis study was performed in parallel with the main survey. Precision, which is the difference between repeated measurements during the survey, was first analysed. For this portion of the analysis, each of the last seven participants of the day were assigned to a particular station in order to be reassessed for a given set of variables after the whole session at the end of each day. Each subject had the same landmarks. Accuracy, which is the difference between the measurements during the survey and the true value, was also monitored throughout the survey to avoid the emergence of systematic bias. To this end, 4 individuals from the survey's team of observers (the landmarkers) were selected. The "true value" was obtained through averaging the values obtained by a group of trained measurers for each of the anthropometric variables. Each of the 4 individuals was re-landmarked and re-measured at regular intervals throughout the survey, i.e. over a period of 2 months. This enabled the survey team to control the quality of the measurements by addressing landmarking and measurement biases. TRUNCATED
