What are the likely maximum and minimum values for this measurement 20.4+_0.1cm
The more precise your instruments of measurement are, the less percentage of error you will have.
A variable is a measurement that can take different "values". I put values in quotation marks because a variable can take qualitative values (for example, colour of eye) as well as quantitative (numerical) ones.
Accuracy. How close you are to your expected value. Precision. How close together you values are.
For a set of measurements, the mean valueis the sum of all the measurement values divided by the number of measurements in the set.
Joint measurement refers to the simultaneous measurement of multiple properties or variables of a system. It involves determining the values of these properties together in a single measurement process. In quantum mechanics, joint measurements can reveal correlations between different physical quantities of a system.
The two types of system measurement are qualitative, which involves descriptions or subjective evaluations, and quantitative, which involves numerical values or measurements.
The International System of Units (abbreviated SIfrom the French Système international d'unités) is the modern form of the metric system and is generally a system of units of measurement devised around seven base units and the convenience of the number ten. It is the world's most widely used system of measurement, both in everyday commerce and in science.The official SI unit of mass measurement is the kilogram (kg). In the laboratory, grams (g) are often used for convenience. Once measured, these values may be easily converted to other metric units of measurement, such as micrograms or picograms.In the United States, the (avoirdupois) pound is used as a unit of mass. It has been officially defined to be 2.20462 pounds per kilogram.

The components of a work measurement system typically include defining the task to be measured, collecting data on the time taken to complete the task, analyzing the data to determine standard times, and establishing performance benchmarks for future reference. Work measurement systems may also involve training employees on proper methods and techniques to optimize efficiency and productivity.
The type of error that reduces the precision of a measurement system due to factors like noise is called random error. Random errors are unpredictable fluctuations in measurements that can lead to variations in the measured values.
The USA have always been the land of the free. So they felt free to invent their own system of measures. The US have their own Gallon and other fluid measures that are different from the standard commonwealth measures. You have decimal inches but still 12 to a foot. Imperial nuts and bolts are so old and dated. In Australia we went metric in the 1970s and haven't looked back since. If it wasn't so French, the Brits would be on it too. It's so much more simple and easy to use.
No. The metric system, since it is based on powers of ten, is better used with decimal representations of values.
Another term for measurement in physics is "quantification", which refers to the process of assigning numerical values to physical properties or phenomena in order to describe and analyze them quantitatively.
