Measurement Errors Quiz Form
Test your understanding of measurement errors with this focused quiz. Please answer all questions to the best of your ability.
Which of the following best defines a systematic error?
*
An error that consistently occurs in the same direction
An error caused by unpredictable fluctuations
An error due to random chance
An error that can be ignored
Which of these is an example of a random error?
*
Fluctuations in temperature affecting measurements
A miscalibrated instrument
Consistent zero offset in a scale
Incorrectly reading the same value every time
Which statement about precision and accuracy is correct?
*
Precision measures repeatability; accuracy measures closeness to true value
Accuracy and precision are the same
Precision means the measurement is correct
Accuracy is not important in measurements
