Statistics
(noun)
the degree of closeness of measurements of a quantity to that quantity's actual (true) value
Psychology
(noun)
The closeness of a measurement of a quantity to that quantity's true value.
Examples of Accuracy in the following topics:
-
Accuracy, Precision, and Error
- Accuracy is how closely the measured value is to the true value, whereas precision expresses reproducibility.
- Accuracy is how close a measurement is to the correct value for that measurement.
- This is an easy to understand introduction to accuracy and precision.
- On this bullseye, the hits are all close to the center, but none are close to each other; this is an example of accuracy without precision.
- Describe the difference between accuracy and precision, and identify sources of error in measurement
-
Variations in Accuracy
- Accuracy is vital to the success of your speech; make sure your facts are correct.
- Choose reliable sources when researching in order to assure your speech's accuracy
-
The Importance of Accuracy
- The importance of accuracy may be illustrated through the example of the Literary Digest Roosevelt-Landon presidential election poll.
- The Literary Digest lost its reputation for accuracy and the trust of the readers and soon went out of business.
- Relevance of the survey information, quality of the data, and overcoming personal bias are integral to polling accuracy.
- Discuss the importance of maintaining accuracy when conducting measuring public opinion
-
Realism
- Realism was an artistic movement that began in France in the 1850s which rejected Romanticism, seeking instead to portray contemporary subjects and situations with truth and accuracy.
- Instead, Realists sought to portray "real", contemporary people and situations with truth and accuracy, including all the unpleasant or sordid aspects of life.

Considerations for Eyewitness Testimony
- However, the accuracy of this initial information acquisition can be influenced by a number of factors.
- The accuracy of eyewitness memory degrades swiftly after initial encoding.
- One classic study was conducted in 1974 by Elizabeth Loftus, a notable researcher on the accuracy of memory.
- Age has been shown to impact the accuracy of memory as well.
- There are also a number of biases that can alter the accuracy of memory.
-
Accuracy vs. Precision
- "Accuracy" is the closeness of a measurement quantity to that quantity's true value.
- When researchers collect data, they strive for both accuracy and precision so that their data are valid and they can reduce variance in their results due to error.
-
Quality of Sound
- Sound quality is an assessment of accuracy or enjoyability of how a sound is perceived.
- Sound quality is an assessment of accuracy or enjoyability of how a sound is perceived.
- Objective measurement is taken when tools are used to gauge accuracy.
-
Setting Transparency Norms
- Accuracy means that available information has integrity, is truthful, and faithfully represents organizational decisions, policies, and practices.
- Organizations that value honesty, trust, and ethical practices encourage accuracy and thereby increase their transparency.

Chance Error
- This target shows an example of low accuracy (points are not close to center target) but high precision (points are close together).
- This target shows an example of high accuracy (points are all close to center target) but low precision (points are not close together).
-
Bias
- Accuracy (or validity) is a measure of the systematic error.
- Accuracy is a measure of how well an experiment measures what it was trying to measure.
- This target shows an example of high accuracy (points are all close to center target) but low precision (points are not close together).
- This target shows an example of low accuracy (points are not close to center target) but high precision (points are close together).
