Gross errors are caused by experimenter carelessness or equipment failure. These "outliers" are so far above or below the true value that they are usually discarded when assessing data. The "Q-Test" (discussed later) is a systematic way to determine if a data point should be discarded.
Instrument error refers to the combined accuracy and precision of a measuring instrument, or the difference between the actual value and the value indicated by theinstrument (error). Measuring instruments are usually calibrated on some regular frequency against a standard.
