In anthropometric measurements, we often hear the accuracy and precision of the terms. What exactly are accuracy and precision? Is it important in measurement? Let’s look at the following explanation.
Accuracy and Precision
Accuracy is the ability to measure repeatedly with minimal errors. Meanwhile, accuracy is the ability to get results that are as close to the actual results as possible.
Accuracy can be determined by a single measurement or experiment, but to determine accuracy requires measurement to assess precision. Accuracy measurements can be accurate but not necessarily precise. Accurate values inaccuracy is affected by the degree of conformity.
Meanwhile, precision measurements can be done once, but the results are not necessarily precise. Because it is necessary to determine the measurement of the server. Precision may be able to experience random errors, so the right values can or may not be accurate, as well as be influenced by the degree of reproducibility.
In taking measurements, accuracy and precision are very important. Because precision and accuracy will affect the appropriate size and bring up the right size results. In addition, a measuring device must have high accuracy and precision to reduce the occurrence of measurement errors.
The Importance of Accuracy and Precision in Anthropometry
In anthropometry, accuracy and precision are important indicators in determining the exact size. Anthropometry itself is a field of science about measuring the dimensions of the human body that reaches bones, muscles, adipose tissue, or fat.
Anthropometry is also used in determining the nutritional status of infants to find out the problem of stunting. Detection of stunting in infants is done by measurements of height, weight, arm circumference, and head circumference. If the anthropometric measuring instrument used is not accurate and precise, it will cause misdiagnosis or examination. That way, precision, and accuracy as indicators in knowing the appropriate size.
In addition to knowing to stunt in children, anthropometry is also often applied in the design of occupational ergonomics. This design requires data on the appropriate size between the human body and the design of the designed tool. To find out the size data, accuracy and precision are needed in anthropometric measuring instruments. If there is no accuracy and precision, then the design of the tools used does not make comfort and excitement in the working system.
To find out the accuracy and precision of anthropometric measuring instruments can be done with calibration. Calibration is the process of testing verification on a measuring instrument to match accuracy with the measuring instrument that has been designed. Calibration is done by comparing a standard that is connected to national and international standards with certified reference materials. The purpose of calibration on a measuring instrument is to achieve measurement dilution.
This, anthropometric measuring instruments before use in measurements must already pass calibration tests. The goal is to know accuracy and precision to get accuracy in measurements.
