Precision as a measure of variation, must be accounted for in your calculations and results. Accurately hitting the target means you are close to the center of the target, even if all the marks are on different sides of the center. An example is how close a second arrow is to the first one (regardless of whether either is near the mark). If the player always makes a basket, even though he strikes different portions of the rim, he has a high degree of accuracy. If the measured values are accurate, they may not be precise as they can be larger or smaller than the target value on a wide range. Three students have made multiple measurements of the solubility of sodium chloride (in g … Accuracy vs. Accuracy refers to how close measurements are to the "true" value, while precision refers to how close measurements are to each other. Precision is indicating the reproducibility degree of any measured quantity. We then discussed precision and accuracy. Precision is a measure of how close a series of measurements are to one another. In contrast, precision is a measure of reproducibility. For this example, consider results from a round of target practice. Accuracy is providing a measure of in what way the measured value comes close to the true value. Scientists use percent error as one method of describing how accurate and precise a value is. But these are shooting skills to keep honing. 52 60 48 41 Object measured is 27 mL volume. If you take measurements of the mass of a 50.0-gram standard sample and get values of 47.5, 47.6, 47.5, and 47.7 grams, your scale is precise, but not very accurate.
