Anthropometric investigators should be concerned about any significant measurement error of their metric data in order to safeguard the integrity of their scientific investigation. This study aimed to demonstrate the application as well as to evaluate the process of Technical Error of Measurements (TEM), relative Technical Error of Measurements (rTEM) and Coefficient of Reliability (R) for precision estimates in terms of intra-observer error using some hand and foot measurements along with the body height of 349 male young adults (college-going students) who were selected from six different randomly chosen co-educational general degree colleges that belonged to five different subdivisions of North 24 Parganas, West Bengal, India.( Incomplete sentence)

All these colleges were chosen from their respective subdivision-wise list of co-educational general degree colleges following a simple random sampling technique.

Along with the demonstration, the output of the application showed that height was found to have the second lowest TEM (0.06 cm), the lowest rTEM (0.04%), and the highest reliability in terms of R- value (1.00). Besides height, all other measurements showed a minimal margin of technical errors in terms of TEM (0.05–0.07 cm) and rTEM (0.20%–0.70%) as well as higher reliability for their accuracy (R ranges from 0.989–0.999). Overall, it concluded that TEM and other estimates might be some reliable tools for better determining the precision and reliability of the anthropometrist for taking anthropometric measurements.
