Difficulties with propagation of error.
Post Body
I have found four values for t, a measurement of 25 oscillations of a pendulum, [39.02, 38.93, 38.99, 38.84], all with a random measuremental error of 0.01, i.e the error on the stopwatch. Through propagation of uncertainty I've found the error of average-t to be 0.005.
The period T=t/25. Does this mean the error on T is 0.0002? This seems really precise considering the original data. If that is the error, should I quote my value for T to three decimal places? Thank you very much.
