Difference Between Accuracy and Precision (with Comparison
Precision and accuracy are terms used to describe systems and methods that measure, estimate, or predict. In all these cases, there is some parameter you wish to know the value of.... There are two ways we can describe these measurements – by their accuracy and precision. Accuracy is a measure of how close your measured value is to the true value or other standard. Although sometimes we use qualitative (verbal) words to describe the accuracy (such as good

The higher the precision, the lower the standard deviation of the results. Accuracy is hard to measure, especially with precision lab equipment, so they usually sell “standards”, which you can dilute with known volumes of water, and create calibration curves. how to get your shoulders back and down In such cases, accuracy could be misleading as one could predict the dominant class most of the time and still achieve a relatively high overall accuracy but very low precision or recall for other classes.
