Is it true significant digits are the number of digits that reflect the precision of a measurement or number?
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
What is the difference between accuracy and presicion?
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
What is a prescribed decimal place called?
It is a specified degree of accuracy or precision.
How are accuracy and precision used when communicating deisgn ideas?
