You measure the oscillations of a pendulum four times, and findthat it makes 15 complete swings in times of 8.29 s, 8.40 s, 8.30s, and 8.41 s.
What is the mean of these measurements?
What is the mean deviation of these measurements?
What is the standard deviation of these measurements?
Your lab instructor asks you to find the period (time for onefull swing) of the pendulum. You should write
Hint: It is conventional to use the standard deviation asthe measure of uncertainty.
