FALSE. This question tests a deeper understanding of accuracy. Let's analyze: Student A: Absolute error = |15.2 - 15.0| = 0.2 cm. Relative error = 0.2/15.0 = 0.0133... Student B: Absolute error = |30.4 - 30.0| = 0.4 cm. Relative error = 0.4/30.0 = 0.0133... While both students have the same RELATIVE error (0.0133 or 1.33%), they do NOT have the same absolute error (0.2 cm vs 0.4 cm). However, the question states they have the same absolute error, which is incorrect based on the data. Even if they did, having the same absolute error doesn't mean equal accuracy—relative error is a better measure of accuracy. A 2 cm error when measuring 100 cm (2% error) is much more accurate than a 2 cm error when measuring 10 cm (20% error). ECZ exams test this concept to ensure students understand that relative error, not absolute error, is the true measure of measurement quality. This is why scientists prefer percentage error when comparing measurements of different magnitudes.
