When an experiment is repeated many times, the random errors and uncertanity are sometimes positive and sometimes negative.

Thus, the average of a large number of the result of repeated experiments is close to the true value and reduces the error and uncertanity.

So, in order to reduce error and uncertanity in measurement of time period of a pendulum, the time for ten oscillations is measured, then simply take the average of the ten oscillations to obtain the time period for one oscillation.
