What Difference Can the Data Make?

Abstract

The anthropometric data which is readily available to the ergonomic practitioner contains gaps in the statures of individuals covered. This study fills in those gaps by analyzing the data sources available to interpolate the dimensions for those statures not represented. The interpolation method used was linear regression relating a specific dimension to the standing stature of the individual. Additionally, this paper compares several sources of data to demonstrate significant differences. Both these pieces of information are important to the practitioner. By filling in the gaps, the practitioner is provided with initial quantitative reference points for individuals when properly arranging a workstation. Currently, only qualitative information is provided concerning optimum workstation design for individuals not represented in the data sources. By demonstrating the lack of a significant difference between data sources, the practitioner may use whichever source is readily available. The results show a significant relationship between the individual's stature and eight different workstation measurements. Finally, there is no significant difference between the data sources examined.
