WebMay 4, 2024 · Accuracy and precision are both forms of measurement that define how close you are to hitting a target or achieving a goal. Accuracy evaluates how close you are to the true value of the measurement, while precision shows how close the measured values are to one another. Accuracy vs. precision: the bullseye example
WebAccuracy and Precision: Accuracy refers to the closeness of a measured value to a standard or known value. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. In this case, your measurement is not close to the known value. WebPrecision is the amount of information whose conveyance takes place by a number in terms of its digits.
