Is a higher coefficient of variation better?
The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage. The lower the value of the coefficient of variation, the more precise the estimate.
What is the purpose of calibration?
Calibration is important because it helps assure accurate measurements and accurate measurements are required for most research, development, and innovation as well as safe and profitable production across virtually all industries of most products and services we use every day.
What is calibration and its need?
Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument. Typically, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. In practice, calibration also includes repair of the device if it is out of calibration.
