For a thermometer with a mark at every 1.0°C, the uncertainty is ± 0.5°C. This means that if a student reads a value from this thermometer as 24.0°C, they could give the result as 24.0°C ± 0.5°C. What is the formula for uncertainty?

WebbThis paper has discussed two very simple examples of how uncertainty budgeting can be used as a tool to improve measurement processes. The first example showed how we can use the uncertainty budget to reduce the cost of measurements, while suffering only a minimal increase in uncertainty, by targeting the areas of high cost and low influence on … WebbVi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta.
