Recently, I encountered several individuals (technical experts) who believed that a manufacturer’s published accuracy specification is characterized by a uniform or rectangular probability distribution. For several years, I have observed the opinions of others who seem to share the same consensus. However, I have never accepted this assumption; so, I thought I would share my […]
When performing experiments, we expect to achieve an approximation of confidence in the results of our observations. When our confidence is high, we typically expect our risk of failure to be low. Therefore, it is important to understand the importance of confidence and risk when estimating the uncertainty in our measurement results. What is a […]
Whenever a measurement is performed, the result is never exact. No matter how careful or scientific, every measurement is susceptible to error and uncertainty. A measurement is the best quantitative estimate of an observation constrained by one or more limiting factors. These constraints establish doubt in the observed result and introduce the concept of uncertainty. […]
