- Homework Statement
- I measured 20 periods of a pendulum and did it 10 times, so from that I calculated a statistical error ##\sigma_A##. Let's say that my reaction time is 0,3 s. What is the total error of the measured period ##T##?
- Relevant Equations
- ##\sigma_T=\frac{1}{20}\sqrt{\sigma^2_A+\sigma^2_B}##
So let's say that my reaction time is 0,3 s, so is then a systematic error ##\sigma_B## for 20 periods 0,6 s? Beacause first I had to start a stopwatch and then stop it. So then ##\sigma_T=\frac{1}{20}\sqrt{\sigma^2_A+\sigma^2_B}##?
