Definition

A measure of the disagreement between the pollutant concentrations reported by the sensor and the reference instrument. One way to measure error is by calculating the root mean square error (RMSE). Additional ways include calculating the mean bias error (MBE), mean absolute error (MAE), among others.

Definition and Description

Error refers to the difference between an observed or measured value and the true or expected value of a parameter or quantity. It quantifies the degree of inaccuracy or deviation in data or measurements from the actual values they are intended to represent. Errors in statistics can result from various sources, including sampling variability, measurement imprecision, or systematic biases in data collection methods. Reducing and understanding these errors is crucial for obtaining accurate and reliable statistical results.
