Please explain uncertainty and give examples
like i know it is 'half the smallest degree'
just not suree.

Precision refers to how close a set of measurements are to each other, while accuracy refers to how close a measurement is to the true or accepted value. In other words, precision is a measure of consistency, while accuracy is a measure of correctness.
Precision and accuracy are crucial for ensuring the validity and reliability of scientific results. Without a clear understanding of these concepts, it is difficult to determine the true value of a measurement and the degree of uncertainty associated with it.
Uncertainty is typically expressed as a range of values within which the true value of a measurement is likely to fall. This range is often represented by a plus or minus symbol, indicating the margin of error.
There are several factors that can impact the precision and accuracy of measurements, including human error, instrument limitations, and environmental factors. It is important to carefully consider and control these factors in order to obtain reliable and accurate results.
To improve precision, one can increase the number of measurements taken and minimize any sources of error. To improve accuracy, one can calibrate instruments regularly and use appropriate techniques to reduce systematic errors. Additionally, having a clear understanding of the concepts of precision and accuracy can also help in making more precise and accurate measurements.
