Measurement error

The type of error that occurs naturally in all series and measurements is...

• Random error

• Systematic error

• Gross error

Select the correct type of measurement error when the error is caused by noise or a change in the environment.

• Random error

• Systematic error

• Gross error

Choose the correct statement.

• There can be more than one type of error in a single measurement.

• The types of errors are mutually exclusive.

• The more accurate the measurements, the less the measurement error matters.

• Inevitably, there is no error in every measurement.

Select the correct option: ________ indicates how close the measurements are to each other.

• Accuracy

• Precision

Choose the right option

• Poor accuracy, good precision

• Poor precision, good accuracy

Choose the right option

• Poor precision, good accuracy

• Poor accuracy, good precision

Which type of measurement error calculation is involved when the error is calculated from the sum of the partial derivatives of the measurement equation.

• Single measurement error or type B uncertainty

• Repeat test or type A uncertainty

• Indirect measurement error

Calculating the type B uncertainty: the Fluke 175 meter reads 12.75 V when measuring DC voltage. Calculate the measurement result.

• (12,75 ± 0,04) V

• 12,75 ± 0,04 V

• (12,75 ± 0,03) V

• 12,75 ± 0,03 V

Calculating the type A uncertainty: the measurement results are: 1.113 V, 1.114 V, 1.125 V, 1.113 V, 1.117 V. Calculate the measurement result.

• 1,1164 ± 0,0023 V

• (1,1164 ± 0,0023) V

• 1,116 ± 0,003 V

• (1,116 ± 0,003) V

Choose the right presentation to report a measurement error

• 10,010 g ± 0,10 g

• 10,01 ± 0,10 g

• (10,010 ± 0,100) g

• 10,01 ± 0,10
