NettetThe reference range would be the central 95% of the data, which falls between the 3rd and 117th values. Outliers can have a substantial effect on the calculation of reference ranges by this method and should be removed. Outliers are data points that lie outside the bulk of the population.

In electronics, the linear operating region of a device, for example a transistor, is where an output dependent variable (such as the transistor collector current) is directly proportional to an input dependent variable (such as the base current). This ensures that an analog output is an accurate representation of an input, typically with higher amplitude (amplified). A typical example of linear equipment is a high fidelity audio amplifier, which must amplify a signal without changing its wav… NettetBias and linearity assess the accuracy of a gage. Bias Bias examines the difference between the observed average measurement and a reference value. Bias indicates how accurate the gage is when compared to a reference value. Linearity Linearity examines how accurate your measurements are through the expected range of the measurements.
