Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You take three measurements of a metal rod’s length: 20.01cm, 20.00cm, and 20.02cm. Calculate the average length and discuss its precision and accuracy if the actual length is known to be 20.05cm.

💡 Hint: Consider how close the average is to the true length for accuracy.

Challenge 2 Hard

A chemical experiment results in three temperature readings: 100.3°C, 100.1°C, and 100.4°C. Assess the precision and any potential errors if the true boiling point is 100.0°C.

💡 Hint: Analyze both precision and accuracy separately.
