Does anyone know how to calculate absolute uncertainty??
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 = 2.393 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
This is what I've done:
so since the instrument uncertainty is 0.001 s then.
t1 = (2.432 ± 0.001)s
t2 = (2.393 ± 0.001)s
t3 = (2.402 ± 0.001)s
t4 = (2.412 ± 0.001)s
t5 = (2.424 ± 0.001)s
help! what do i do? do i add the uncertainties together like 0.001 + 0.001...?
