Define systematic error and provide an example.

A systematic error is an error that only occurs once in a measurement.

A systematic error is a consistent, repeatable error in measurement, such as a miscalibrated scale that always reads 2 kg heavier.

A systematic error is a random error that varies with each measurement.

A systematic error is a type of error that cannot be corrected or identified.

What is random error and how does it affect measurements?

Random error is the predictable fluctuation in measurements that ensures precision.

Random error is the unpredictable variation in measurements that affects their accuracy and consistency.

Random error is a systematic bias that improves measurement accuracy.

Random error is the consistent deviation in measurements that enhances reliability.

MULTIPLE CHOICE QUESTION

Explain the concept of uncertainty in measurements.

Uncertainty in measurements is the doubt about the accuracy of a measurement, expressed as a range or margin of error.

Uncertainty refers to the total number of measurements taken.

Uncertainty is the confidence level of a measurement without any error margin.

Uncertainty in measurements is the exact value of a measurement.

MULTIPLE CHOICE QUESTION

How do you calculate the uncertainty of a measurement?

Use the average of all measurements as the uncertainty.

Multiply the measurement by a constant factor to find uncertainty.

Combine individual uncertainties using root sum of squares to find total uncertainty.

Add the measurement error to the value directly.

6.

MULTIPLE CHOICE QUESTION

What is the difference between absolute uncertainty and relative uncertainty?

Absolute uncertainty is always larger than relative uncertainty.

Relative uncertainty is a fixed quantity; absolute uncertainty varies with measurement.

Absolute uncertainty is expressed as a percentage, while relative uncertainty is a fixed number.

Absolute uncertainty is a fixed quantity; relative uncertainty is the absolute uncertainty as a fraction of the measurement.

7.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Define accuracy in the context of measurements.

Accuracy is the consistency of repeated measurements.

Accuracy refers to the precision of a measurement.

Accuracy is the degree to which a measurement reflects the true value.

Accuracy is the average of all measurements taken.
