Measurement and Uncertainty

Uncertainty in measurement

​

Multiple Choice

Which type of error will give a more accurate result when taking more measurement:

• Systematic

• Random

Multiple Choice

Which type of error would be the result of a poorly calibrated scale?

• Systematic

• Random

Multiple Select

The temperature of boiling distilled water was measured 5 times, The results were 103.7 C, 102.6 C, 102.3 C, 104.1 C, and 103.4 C. What type(s) of error are present?

• Systematic

• Random

Multiple Choice

A measurement was taken three times. The correct measurement was 68.1 mL. The measeurements taken were 75.2 mL, 74.6 mL, 74.9 ml. Choose how you would describe the measurements:

• Accurate

• Precise

• Both

• Neither

Multiple Choice

A measurement was taken three times. The correct measurement was 68.1 mL. The measeurements taken were 75.2 mL, 74.6 mL, 74.9 ml. Choose how you would describe the measurements:

• High in random and systematic error

• High in random error, low in systematic error

• Low in random error, high in systematic error

• Low in both random and systematic error
