Measurement of sizes of geometrical structure can have small units based on the metric system. Profilometry was an important aspect of research study (National Measurement Institute 2022). Inaccurate data collection can impact the results. These processes can change from vernier-caliper and micrometer to microscopy. The former was regarded as quantitative methods and the other qualitative for data collection. The research showed the external factors contributing to inaccuracy can be reduced using qualitative methods.
