Question

A student repeatedly measures the time taken by an object to cover a certain distance and obtains the following data:

t₁ = 2.432 s, t₂ = 2.391 s, t₃ = 2.402 s, t₄ = 2.412 s, t₅ = 2.424 s

The instrument uncertainty is 0.001 s
What should the student report as the absolute uncertainty in the measurement? HINT: The absolute uncertainty can be given by either the instrument uncertainty or the standard error (approximated by R/N) in the measurements

Report your answer to two decimal places.
