Question

Quizplus · Accepted Answer

This type of error is known as random error, which results in inconsistent readings each time the measurement is taken. It is caused by various sources of variability, such as changes in ambient conditions, fluctuations in instrument sensitivity, or human error. As a result, random errors tend to cancel each other out when measuring a large number of samples and can be minimized through repeated measurements and statistical analyses.
