Question 1

What is a systematic error?

  • An error that varies unpredictably
  • An error that consistently skews results
  • An error that is always positive
  • An error that is always negative

💡 Hint: Think about errors that do not change and always influence measurements the same way.

Question 2

True or False: Systematic errors can always be completely eliminated.

  • True
  • False

💡 Hint: Consider how instruments can drift over time even with calibration.

Challenge Problems

Push your limits with challenges.

Question 1

A scale consistently reads 3 grams heavier than the true value. A user measures a sample that weighs 10 grams according to the scale. Calculate the actual weight.

💡 Hint: Subtract the amount by which the scale is off from the measured weight.

Question 2

In a series of experiments, a thermometer consistently reads 2°C higher than the actual temperature. If an experiment is conducted at a recorded 25°C, what is the actual temperature?

💡 Hint: Adjust the recorded temperature down by the known systematic error.
