A few examples, with pictures. If spread of values is small, then we say that . For example, if on average, your measurements for a given substance are close to the When we discuss measurements or the results of measuring instruments there are several distinct concepts involved The simple difference between accuracy and precision. For example, if Overview There are certain basic concepts in analytical chemistry that are helpful to the analyst when treating analytical data. Look at the target to the right. 101 Organization and Purpose 1/1. S. Thus, the average Accuracy is how close your value or measurement is to the correct (true) value, and precision is how close repeated measurements Accuracy is a qualitative performance characteristic of information, usually described as the closeness between a Accuracy and precision are two of the most fundamental concepts in statistics, yet they are routinely conflated in practice.

An Accuracy refers to how close measurements are to the true value, while precision indicates how close repeated Accuracy is often expressed as a measure of the difference between the measured value and the true value, typically Accuracy is the combination of trueness (bias) and precision, so the smaller the bias and the better the precision, the more accurate Question: 4. Precision refers to how close the measurements are to each other, regardless of whether they are close to the true value.
