QA Plans consist of primarily two functions: (1) the QA function which is the assessment of the quality of the data (accuracy and precision) and, (2) the QC functions which are the activities that maintain or improve data quality. These two functions combined form a control loop.

Accuracy vs. Precision: Most people use these two terms almost interchangeably, and few people actually use them correctly. In science, they mean very different things, both important to assessing data quality. Accurate means “capable of providing a correct reading or measurement." In physical science, a measurement is accurate if it ...

If the true value is not known, then the accuracy of measurement can only be estimated (typically, this must be done with extreme care). Measurement Precision: an indication of the reliability and/or repeatability of a measurement, as reflected by the number of significant figures used to represent the measured value.
What Is the Difference Between Accuracy and Precision?
Precision: ACCURACY. HIGH LOW. Place 4 dots on each target with the appropriate level of accuracy and precision. HIGH. PRECISION. LOW. Block 3. Name: Date: Pd: Mark each set of numbers as having a high or low accuracy and precision. Ex: Object measured is 1.0 meter long. 1.15 1.10 1.12 1.30 Object measured is 50 cm length ...

Rotten Rulers: Accuracy and Precision In this interactive lesson, students learn the difference between accuracy and precision. Students measure the area of an index card using miscalibrated rulers and compile a class set of data. Students analyze the data and determine which ruler is the best tool.

accuracy. of data depends on how close a measurement comes to the actual or “true value.” The accuracy refers to being “correct.” The . precision. of the data depends on how close several measurements are to each other. The precision of the data refers to data being “reproducible.”
