Understanding Precision and Accuracy: Demystifying Uncertainty in Measurements

Click For Summary
Uncertainty in measurements refers to the doubt that exists about the result of a measurement, often quantified as a range of values. It is commonly defined as half of the smallest division of the measuring instrument. Examples include the uncertainty in a ruler measurement, where a reading of 5.0 cm might have an uncertainty of ±0.05 cm. Understanding uncertainty is crucial for accurate data interpretation, as it affects the reliability of results in scientific experiments. Comprehensive resources, including textbooks, provide in-depth explanations and examples of measurement uncertainty.

Please explain uncertainty and give examples

like i know it is 'half the smallest degree'

just not suree.

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
