Challenge Problems

Push your limits with challenges.

Question 1

An experiment produced a measurement of 12.0 with an uncertainty of ±2.0. If you plot this point on a graph with other measurements, how would you draw its error bars?

💡 Hint: Think about the range that uncertainty indicates.

Question 2

A scientist collected data with a maximum gradient of 8 and a minimum of 4 when considering error bars. What is the uncertainty in the gradient?

💡 Hint: Consider the difference between the maximum and minimum values to find the uncertainty.
