Accuracy

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).
