Precision is the repeatability, or reproducibility of the measurement Precision指的是测量结果的一致性。 Accuracy is the proximity of measurement results to the true value. Accuracy指的是测量结果和真实结果的接近程度。 在心理学度量中,precision类似于reliability(即信度);accuracy类似于validity(即效度)。
The deviation of a measurement from its value is referred by accuracy. These deviations have two components including, a systematic and a random. The systematic error is constant, while random errors vary. The instrument which is accurate is valid and precise and an inaccurate measurement is ...
In some publications, the terms "precision" and "accuracy" are used as if they were synonyms for "reliability" and "validity." This article shows that these terms are neither precise nor accurate when used in this way. Scales can demonstrate high test–retest or interrater reliability (i.e...
it evaluates the “correct on average” aspect. You can have data that are correct on average but fall relatively far from the proper value. That still counts as accuracy!

The terms accuracy and precision are consistently differentiated in the literature of engineering and the “hard” sciences. Precision shares a common core of meaning with reliability as used by behavioral scientists. Accuracy and validity have a similar semantic overlap. A review of the ...

subluxation/translation (score 4) and kyphosis/scoliosis (score 2). This was likely due to the presence of only 2 of 1222 patients with a score of 4. Therefore, eliminating the subluxation/translation level because of the scarcity of cases may improve the accuracy and reliability of the SINS...
The article provides information on the concept of precision and accuracy in medical field. It states that accuracy is similar to validity and refers to how close the measured value comes to the true or actual value. In terms of accuracy of equipment, it is supported by ensuring the appropriat...
accuracy and precision. Accuracy refers to how close the assessed age of a sample is to the true age. Precision refers to the statistical uncertainty associated with an age estimate—the greater the precision, the less uncertainty there is in the assessed age. However, a precise estimate of th...
