This is from a laboratory exercise. I was asked to measure the time it took for a pendulum to cover 3 periods. I repeated this 25 times, to get 25 measurements for as many trials. I also calculated the standard deviation from the measured data (calculated for different question).
The question I am stuck on, is however, the one that concerns finding the uncertainty in the overall average of the pendulum data. Any help is appreciated.
I am given this equation for finding the average uncertainty.
[tex]\sigma[/tex]average = [tex]\sigma[/tex] individual/ square root of n
n being number of trials.
The Attempt at a Solution
So, the equations asks for the uncertainties of individual measurements. Can I somehow calculate the individual uncertainties from the standard deviation or the average?
Thanks a lot.
