Final answer:
Acceptable accuracy of monitor readings is best assured by calibrating the monitors regularly to ensure that their readings are close to the standard or true values.
Step-by-step explanation:
Acceptable accuracy of monitor readings is assured by calibrating regularly. Calibration is the process of adjusting the readings of a measuring instrument to match or be linearly related to the values of a known standard. Regular calibration is essential to ensure the accuracy of measurement devices, similar to making accurate measurements of an object's length with a ruler. Throughout various industries and scientific applications, accuracy is critical as it ensures that measurements are close to the true value. For example, the measurement of standard computer paper, which is supposed to be 11.0 inches long, would be considered accurate if it is measured within a very close range to this value, such as 11.1 in., 11.2 in., or 10.9 in. In contrast, a measurement of 12 inches would not be accurate. While using multiple monitors or replacing them regularly may have an impact, these options do not directly ensure the accuracy of the readings as calibration does.
