• ### Uncertainty Budget Example

Need to estimate uncertainty? Then, you will need a calculator to create uncertainty budgets. In this guide, you a see an uncertainty budget example from our Simple Uncertainty Calculator. This guide will cover all of the elements that are part of an uncertainty budget and why you need them. Plus, you will see plenty […]

• ### How to Perform a Repeatability Test 3:

Collecting Data Before you can analyze and evaluate the measurement system and process, you must collect some data. However, before diving in head first, there are some things that should be considered. Review the Plan First, review your plan. If you do not, you may find yourself repeating the experiment. It is more time efficient […]

• ### 6 Influences on Uncertainty in Measurement Results

When performing uncertainty analysis, it is important to consider what influences uncertainty, not errors, in measurement results. Here is a list of six common influences that will bring awareness and enlightenment to all who perform measurements.   01 | Equipment The equipment selected to perform tests and calibrations is important. It can severely impact […]

• ### Rounding Uncertainty in Measurement

Rounding uncertainty in measurement has recently become a topic of great debate. For several years, many Accreditation Bodies (AB) and assessors have asserted the implementation of the ’round up’ method, which forced Certified Accredited Bodies (CAB) to round up their estimated Calibration and Measurement Capability (CMC) values. Although this method of rounding is acceptable, it […]

• ### Confidence Intervals and Risk in Measurement

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 […]

• ### Introduction to Measurement Uncertainty

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. […]
