Accuracy, Precision, and Error | Introduction to Chemistry
Accuracy is how close a measurement is to the correct value for that measurement. The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions). Measurements can be both accurate and precise, accurate but not precise, precise but not accurate, or neither.

Improving measurement accuracy
Improving measurement accuracy What is it? Variation is inherent to any system, and the data collection process is no exception. However, excessive variation in the data collection process will appear as variation on the control chart and can have a negative effect on process analysis. In addition to using operational definitions to ensure measurement consistency, you should periodically ...
Precision Measurement | Analog Devices
High accuracy is maintained for input waveforms with crest factors of 1 to 3 and crest factors at % or less with respect to fullscale input level. The AD737 has no output buffer amplifier, thereby significantly reducing dc offset errors occurring at the output, which makes the device highly compatible with high input impedance ADCs. Requiring only 160 μA of power supply current, the AD737 ...
